CTEK Battery Chargers

[Invasionss]

Hi Peoples,

I came across these chargers a little while ago, but just recently looked into them alot more.
They are said to be the bees knees, the ducks nuts, etc, well you get what i'm trying to say. They say that they can be connected up to your battery without disconnecting from the terminals.

Has anyone on here got one & how do you rate it?
They aren't badly priced either, depending on where you look.

Thankyou.

[dandaman]

I've got one, they're a very good charger, and yes they can be switched on while the battery is still attached to the car.

Was obviously more expensive, but it's a good charger which I'll prob have for life, Made in Sweden, and are factory installed by some top end European car manufacturers which aren't driven daily, so the battery is always in peak condition.

There's my plug for them

[Yoda]

I have a CTEK charger. Great piece of kit.
Can charge the battery while connected - Zero spark. Has a proper float mode, so you can leave it connected indefinitely and they have a special higher voltage setting to charge the Sealed AGMS/ odyssey battery's etc.
Mine is also waterproof so you can use it outside.
cheers

I have had one for about a year. I think its a very good charger. It charged a battery for my boat that had been discharged for a while, which my $50 charger wouldn't charge. So basically saved me buying a new battery.

[vessloveit]

These are excellent chargers, we use them in standby diesel fire pump starting/charing circuits to keep batteries charged.

[VSSTATO5.0]

Is the charger just for general use, or is it for a car that does not get driven much?

[heavyduty1340]

Ive had one for a year now and I rotate it between the harley and the monaro
That way they are always fully charged if I want to take either for a run

They seem to be really good quality too

[Invasionss]

Thankyou all.

Looking at the 7000 model as it has the RECOND function to help fix the acid stratification process. I really don't have a problem with paying the big money for a great charger.

Ok, question for Dandaman. The high priced European cars have them factory installed.
Does this mean that they are never taken off the cars at all?
How does the charger actually charge the battery if fully fitted under the bonnet?

If anyone else can add, please do.

[VSSTATO5.0]

That's why i asked what you were using it for.. I have a Projecta battery charge n' maintain unit myself.. It is on the g/f's little race car atm.. They come with good mounts, and all the cabling you need to mount them in the bay, and bolt directly to the battery.. Drive in, park, plug it in and forget it.. Keeps your battery in tip top condition, and ready to fire whenever you like..

They come in all different sizes and rates to suit whatever you want.. I have the 1600mA (ac250b is the model num) myself, and this was on my fo...f..for.. ( you know that other brand of car) for a long time and never let me down...

I believe when you shell out for a Ferrari that they have a CTek charger fitted from factory. Don't quote me but I think they are fitted behind the glovebox out of view. Not sure on how they are wired into the system but they are designed to maintain and charge the battery while your pride and joy (Ferrari) is put away in the garage for any lengthy period of time.

[Invasionss]

Sorry VSStato5.0,

The ute is driven daily, but looking at extending the level of performance from the battery as it's still the original one from the holden factory. It's coming up to 6 years of service.

Stuff it, I just bought a brand new CTEK Multi XS 7000 model on Ebay saving myself $95.00. Probably can't get better than that.

[fastrc]

Timely thread, been researching these units for use on a Hotrod with limited road use.
Is the MULTI XS 7000 adequate for most car applications, or is it better to spend slightly more for the MULTI XS 15000 ?.

[HSV590]

The XS7000 would be perfect fpr what you want it for, the nice bonus thing with the XS7000 is it has a power supply mode built in..

[Invasionss]

Fastrc,

I would think anything up to the 7000 model will suit your needs, but don't quote me! But going off what they say on the number of websites offering CTEK chargers for sale, all will keep yout battery charged with limited use so you can go for your happy drive. I only choose the 7000 as it was the first in the line up with the "recond" function which I needed.

The 15000 I think goes into bigger battery sizes for heavier vehicles.

[Invasionss]

And today being the day, it's drain the old oil & add mainlubes flushing oil for a squeaky clean cleanout of the engines inner maze :dancenana:, my battery dies on me!!! :flamin::flamin::flamin:

I guess it's better for your battery to die at home, than anywhere else...

[BECAUZ]

Ok so from this thread I've worked out which charger to buy, the CTEK XS7000. I'm away for work a fair bit and just want to keep the battery charged.

Is this what i need?

Also does anyone know where the best place to get them from is?

I found them here but if i can save a few bucks may as well. Thanks in advance

Mate,

I bought the Ctek XS4003 on Ebay, I see the same company has the XS7000 for $205 and postage is free. I got mind in three days, no problems.

[Benton]

I have had one connected up to my car for two years now and never had a problem. Highly recommend you pay the bit extra for the CTEK as opposing to other brands such as Projecta - especially if your planning on hooking it up to your battery whilst still in the car.

My boss has a 599 Ferrari and they do indeed come with a small ctek charger. They are not mounted in the car but are pluged into a 12 volt socket in the boot when needed.

Having purchased a few items from them (C-Tek marine charger and Optima batteries), I can recommend the Batteries Direct mob - excellent service and good prices.

cheers

[OVZ-346]

i have a c tek charger wired up to some of my "investment cars" that sit in the shed and never go anywhere ,theyre great for this situation

i love the thing and even better if my ute is dead flat plug in the old c tek and 15 mins later it will start.... amazing bit of gear

[BECAUZ]

How long is the lead for the ctek charger? I sometimes park my car outside the garage and was wondering if i could mount the charger in the engine bay and just have the lead come out and under the garage door.

[Wonky]

I bought my PROJECTA AC250B through them , good hassle free service :goodjob:

I actually contacted Projecta by email and they didn't recommend the AC250B for my Optima D34, saying it was too small for it, though probably fine for OEM battery. Ended up with a CTEK XS4003 from Optima themselves for about $120 which is a bit more expensive. 8 step charging process, can be left connected on car and used when you like, won't overcharge.

[vessloveit]

I have a CTEK XS7000 have not needed to use on my VE yet. Loaned it to workmate for his VE and has not had any trouble with battery again.

Also the recondition mode can sometimes gain you some life out of what most people would think is a buggered battery.

[XUV]

though probably fine for OEM battery. .

exactly , it's only designed to maintain the battery , to keep from dropping below a certain voltage .

Working well so far this winter .

[Plenty]

WOW, just rang a number of places here in WA regarding the Ctek 7000,
Prices ranged from a decent $248.99 through to a wallet lightening $351.00.

Cheapest i could find online was e-bay or smarterlife.com.au for $205.00 shipped.
Interesting to note from one of the Battery experts i spoke to is that if you use a sealed maintenance free acid battery and it has run dead flat, the acid actually perishes and the only way to charge it would be on a "manual charger" whatever that is.

Might get one from e-bay i think.

[XUV]

the equivalent projecta is only 160 posted , and it's Aussie designed .

for 215 you could get a 15amp one

answer all 3 of my questions on brake boosters and on the AC250 I asked :goodjob:

[OVZ-346]

I have maintenance free acid based batteries in all of my cars and I have run my gts dead flat several times to the point where it won't even unlock

Throw the c tek on and 15-20 mins later it will start no worries

[mummbles]

You can get the CTek XS4003 from RACQ for $110 if you are a member.
Ordered mine today.

[Wonky]

Saw that last night when I was doing a search for someone else - great price - best I've seen yet by close to $10. Wonder if they count other RAC members as members eg. I'm a member of RACV?

[Blakrok]

Can someone explain the difference between the XS4003 and XS7000 in basic terms?

Im currently using a $15 trickle charger from JayCar for my race car which keeps the charge up at home but when I get to the track I have trouble starting it.

From reading the limited info on the CTEK website these have some sort of battery reconditioning feature.

[CharlieDontSurf]

I just bought a xs 15000 on ebay. $285 shipped. Got it 48hrs later.It just charged my camper trailers 100ah battery fully that wouldnt hold a charge with another friends battery charger. As someone else mentioned saved me the cost of a new battery.

It also has a suppply mode that you can run 12v stuff without even having a battery connected. This function is obviously not as good for a car as a camper or caravan.... unless you have a really long lead:rofl:

Everyone on myswag.org swears by them. And even though they are designed in sweden, they are now made in China (like everything else)

[huggies]

i have the Ctek XS2500 for a while now it does the job...
wish i could find somewhere to buy the optional wall mount though :(

The Multi XS4003 bridges the gap between the XS3600 and XS7000 by providing all the features of the XS7000 such as the full 8 step charging process (not present in the XS3600), but at a more competitive price.

The difference between the 4003 and 7000 is that the 4003 delivers less power and hence will take longer to charge a battery than the larger XS7000. By example, the 4003 will take 12 hours to charge a 60Ah battery to 80% charge, whereas the XS7000 will charge the same battery in 8 hours.

Not sure Wonky. I know other auto clubs get roadside assist up here, but not sure on the online shop and discounts though.

[VXSS346]

Looking at getting one of these too, just to keep the battery charged up when not in use.

One technical question though. :D What is so different about this charger that allows them to charge even when the accessories are connected, as well as not having to undo the water caps?

[HSV590]

They are just that smart, hence their marketing slogan, "Smartest battery charger on the world"..being a smart arse now, I think it's all to do with the electronic wizardry they are able to build into these units..The beauty of these things is their plug and play nature. Hook one up to your battery, turn it on and go on holidays for a month, battery still fully charged when you return.

[R8HSVHRT]

Just purchased a ctek on saturday to charge the optima great unit plug in and forget goes into palse mode when fully charged just disconnet when your ready to drive the car

[VXSS346]

Whats the best price people can get on the XS 4003?

[mummbles]

$110 from RACQ for members. Check with RACV?

[R8HSVHRT]

The Ctek XS4003 is a 4 amp it has been replaced with a new model MXS5.0 which is a 5 amp cost me 120.00 from Extreme Batteries Montrose

[CALDIR]

Hi

I thought the XS4003 and MS5.0 were 2 different models both in CTEK's current range. Who told you the MS5.0 is to replace the XS4003?

[R8HSVHRT]

I bought the unit from extreme batterys they said both units have the same functions the only difference in the mxs5.0 is a 5 amp and would be a replacement to the XS4003 which is a 4 amp

[HoldenOnn]

I have just bought the new MXS 5.0 battery charger about a month ago. I have charged every battery at my house including 3 cars, a motorcycle, and even charged successfully 2 other batteries that were given up for dead by using the reconditioning function.

I don't do things by halves. I researched like there was no tomorrow in relation to chargers before buying. I searched on the internet regarding recommendations. I emailed a dozen members on here which owned and used Ctek Chargers, and I spoke to my best mate who is an Auto Electrician. Nothing but fantastic reports on Ctek Chargers.

I went with the 5.0 amp charger as opposed to the 7.0 amp one, due to it having the capability of charging smaller capacity batteries such as my motorcycle.

Thanks guys.

[sik66]

I've got 2 mxs5.0!(come across the 2nd one in a Cash Converters and couldn't leave it there for the price they wanted!!!..$30!!)....they are by far the best battery chargers/conditioners I've ever had!!....Youl like!...

[heavyduty1340]

I have a small ctek for my motorbike which has been great for the last 5 yrs

I also have a $700.00 HUGE MOFO at work that can start a car etc, but I am sick of the size and weight of it, so I recently bought a Ctek 15000 to try out

Well the MOFO is now relegated to the cupboard, and the Ctek 15000 has well and truely replaced it. This machine is the ducks guts.

I had several deep cycle batterys ($300.00 ea) that would only hold charge for 2 days, so I charged and recond them on the Ctek, and 1 week later they were still fully charged, so I put them out to work in a machine, and they havent stopped holding a charge yet - money well spent:bow:

I picked it up on evilbay for $228.00

[I Wish]

I have just recently purchased a nice VE SSv MY08.

On my previous cars I have used a Ctek XS 4003 to occassionally top up the battery every once in a while to keep them in top condition.

Since the battery is mounted in the boot now with the Jumper posts in the engine bay. Can I just connect the charger to these posts to charge the battery?

If I connect it directly to the battery in the boot. I will have to leave the boot open with the boot light on etc.

Thoughts?

[decoupe]

I have the same set up in our BMW , I simply connect to the posts under the bonnet and all is fine ....

[AllWheelSlide]

For your VE with some care not to short on car body you can use a socket to remove the positive post; then you can slip positive electrical eyelet lug connector on and put the jump post back. Similarly for the negative, then you can just use the ctek connector plug for your charging. No issues or dramas.

[Toddler78]

I only bought one of these last night on ebay for $65.00

almost bought one from the US for about $30aus delivered until I checked the specs of the units they are only 110 volts over there just for everyones info

this was only the small one (800) but only using it for my bike, plan on wiring ing the eyelets on the battery so I only haveto plug it in to the side of the fairing. if Im happy with it Ill buy another one for the Monaro

[Spoolin]

I have just bought one also after reading and talking to people and a mate from Century Batteries recommended the CTek. I've got the new XS 0.8 which I have the leads permanately mounted onto my 1098's battery.
As i'm riding it a fair bit at the moment, I've got it plugged into a wall timer which is on for about 1 hour a day, maybe make it longer during the winter months.

[I Wish]

Thanks. At last a decent forum.

just received my package :dancenana: I was reading the instruction manual and it was saying that whilst on maintence charge the charger will only send a pulse of current when the battery drops below the perscribed charge. Might be better to leave the charger plugged in and powered 24/7?

Correct, I have an MXS 5 and have it connected to my jetski battery 24/7. After 10 days of being connected charging at 0.8A it then sends pulse current to maintain the charge at 100%

[GTS PAUL]

I have had mine for over a year. Works well. Compact and like the recondition function

[Blakrok]

I drive my ve ute on sat+sun only, sits under a cover every other day, but engine starts first go every time like new (its 1.5yrs old) would i need 1 of these chargers?

[Evman]

I've had one for a while now and it's terrific except for the fact that it plays havoc on my aftermarket alarm which senses battery voltage as one of the triggers. If there's a voltage spike whilst the car is locked the alarm goes off, thinking that someone's tinkering with the car trying to get in.

Random alarm activations at all hours doesn't do well with the neighbours.

[Toddler78]

I drive my ve ute on sat+sun only, sits under a cover every other day, but engine starts first go every time like new (its 1.5yrs old) would i need 1 of these chargers?

look it probably wouldnt hurt, I bought mine for my bike as the battery (4months old) is now completely flat, my monaro I might not drive for a few weeks so I intend on buying another one for that If your driving it for a few hours each weekend that will help keep the battery charged but what I like about these is they will also condition the battery so that it will have a longer life

[QldKev]

My commodore has been sitting around more than usual lately, and I've noticed it was getting slower to crank. I used my 100 year old taper charger to get a bulk charge out the way. After reading this thread I got myself a CTEK MXS 5.0 from ebay ($95 delivered), and it arrive today. I'm reading the manual about the RECON function. It mentions "Recond your battery once per year and after deep discharge to maximise lifetime and capacity."

Do I need to disconnect the battery from the car before using the RECOND function (as it is 15.8v/1.5a)?
After the old charger finished (a few days back) the car seems to be starting good, is it still advisable to do a RECOND as it is a 2 year old battery?

I found the answer to the first question.

Q. Does the battery have to be disconnected from the vehicle when charging with a CTEK charger?
A. No, CTEK chargers cannot damage sensitive electronics so you do not need to disconnect the battery from the vehicle. However, particular attention must be paid when Boost/Recond mode is used as the voltage is 16V. If the voltage is below 16V, most manufacturers consider that everything is in order and CTEK chargers are well under this level, with the exception of Boost/Recond modes. Bear in mind, however, that high voltage shortens the service life of some components. A rule of thumb says that if you raise the voltage by 5 %, a light bulb will lose half of its service life, but normally the problem is not that great. If you have sensitive electronics where the manufacturer advises against higher voltages: Disconnect it!


I assume since my battery is over a year, that the yearly maintenance is recommended.

[R8HSVHRT]

I have the ctek mxs 5.0 as well it stays plugged in and powered 24/7 starts every time

[GR346]

I really need to get around to getting one of these given the amount of time Im away with work and the R8 just sits in the garage
Theres some good info in here - cheers guys :)

just bought 1 today from repco $119, charging my car this very minute..looks like a great product

[heavyduty1340]

Ive got 3 of the suckers and they get shared between the boat. bike and cars for reliable starting

I havent tried other brands for this, but the C-Tek are so good, why try others??

MXS5.0 would be sutable , the one i bought will be used on my bike as well as my ute and a mate's ute that is equiped with a blue top optimia.

[XUV]

I just got one , an MXS 5.0 @ $95.00 delivered , I couldn't say no .


Which model is best for my application? I will be using it for my VE, mower and bike.
The MXS 5.0 is a 5 amp and you can use it as a normal battery charger and better for your modern AGM and Calcium batteries .

I see Projecta's AC250B's on ebay for 50 bucks - good price - it'll do ya mower and bike easily ,
my AC250B is on my HQ tonner fire fighting rig , full time , keeps it's battery nice and fresh .

[2010blackve]

Thanks for the responses A^K^T and XUV.

I am going to order the MXS 5.0.

Cheers

[BLACK 346]

I am about the purchase the MXS 5.0. Am I correct in assuming that this can be left permanently connected to the battery and can charge whilst the battery is still connected to the vehicle with the cell caps on? Basically just want it to maintain the battery when the car sits for long periods.

[XUV]

yep , you are correct , it'll show what stage it's at , ie if it's just sitting at charging ,float or gone to pulse

I recently got one, and checked this out. Yep sure enough they can be left connected, and no need to remove the caps. UNLESS you are running the recond mode, in which it is recommended to disconnect the battery to protect any volt sensitive gear in the car.

If the voltage is below 16V, most manufacturers consider that everything is in order and CTEK chargers are well under this level, with the exception of Boost/Recond modes. Bear in mind, however, that high voltage shortens the service life of some components. A rule of thumb says that if you raise the voltage by 5 %, a light bulb will lose half of its service life, but normally the problem is not that great. If you have sensitive electronics where the manufacturer advises against higher voltages: Disconnect it!

Thanks guys, sounds perfect :)

[RAWKUS]

I have radio control gear and thought it may be relevant to throw this in the mix.
I have an array of Lithium Polymer batteries, Nicad, Lead Acid and NIMH for various items. As I needed a charger with different characteristics, I opted for a balance charger (to take care of multi Cell Lithium batteries that need to be monitored individually whilst being charged). The unit is programmable for Temperature, Voltage and Time cutout, Adjustable Output Amps and voltage, different chemistries, storage modes if batteries are not going to be used for a while (Important for lithium as keeping them fully charged in storage reduces life (apparently). A big benefit is the monitoring. The display tells you how many mA have gone in, it can cycle discharge/charge multiple times batteries to get them back up to condition (Memory re-train) and is USB connectable with software to view on your PC to keep track of battery performance. I use it for Car batteries no problem and mine is 8amp output. Higher versions are available. Look in the RC categories on ebay and check them out. Not too expensive and since it's been a while that I bought mine, I'm sure there are maintenance versions that would be available nowadays comparable to CTEK and the like.

[bush_basha]

I finally bought myself one of these ctek. charge the battery. but I won't be driving the car for awhile so can I just leave the ctek plugged in all the time and it'll do it's own thing and not damage the battery or car?

also can the car be started with the ctek plugged in and still on charge or does it need to be disconnect prior to starting.

thanks

[CALDIR]

Hi

Yes you can leave the CTEK plugged in for years and let it do its own thing.
Not sure if you should start the engine with it connected though, I wouldn't.

They are fine to leave plugged in and turned on. And yes, you could start the car with it still plugged in, it wouldn't hurt it all. Inbuilt protection guards it from any potential spikes/feedback... I'm assuming you've only bought the smaller 5 or 7 amp unit, I'd be wary about leaving the bigger 10, 15 or 25 amp ones plugged in for an extended period of time..

[Big_Valven]

If referring to Ctek chargers it doesn't matter whether they're 5 or 25 amps, they're automatic so they can be left connected and running indefinitely - that's the point of an automatic charger. The amp rating just alludes to the charger's peak capacity charging a severely drained battery.

Starting the engine with most smart chargers is fine as they all have overload protection although I don't really see the point of starting a car with a charger connected if the battery is fully charged.

[bush_basha]

thanks for the replies guys, mine is the 10 amp one.
the reason I would start it with the ctek connected is only just to fire it up, idle it and shut it back down again just to flow around the oil and rotate it around and what not and then continue with keeping the battery charged

Whist what you say is essentially true, I take it you haven't seen what a 25amp charger can do to a battery that's been left on for an extended period of time. I know from a sales/marketing point of view they say they are a "smart" charger that can be left on constantly, but, using a 25amp charger as a "trickle" charger is overkill...

[mr.kiss]

I've got the CTEK 0.8Amp version I mainly use it for my bike, charged a flat battery overnight. But i've also used on my SS when it been laided up for a while. I found it works fine as a trickel maintance charger for a car battery, but I wouldnt use it to charge a flat car battery unless you want to wait a week to charge it!

[Blown 454 AWD]

Had one of these myself for a couple of years now, cycles the battery to stop it sulphating, best charger.

Got the shits the other day and bought a Lithium Battery for the Advantra,

so much smaller it fits in the battery box sideways.

Has 1750 Crank rating and spins the engine at close to double crank speed.

Had a stupid retail price of $1400 :eeeeek:

They reckon 10 minutes to fully charge and holds full charge for a year no problem (without top up)

Steve which lithium battery did you get. I was researching them a couple of months ago but couldn't find anything direct plug and play

[Blown 454 AWD]

SSB PowerSport Lithium

No special chargers, runs 14.5 volts

This battery is plug and play

They are a big fire hazard (check YouTube, starting a fire with a AAA lithium battery, goes like Magnesium when exposed to air)

Hi Guys

A little help
I recently purchsed a Ctek MXS 5.0 charger and conected it to my VT SS to try and charge the battery. Its been sitting in the shed dead foir about a month, batteriy is about 8 months old. The charger won't even acknowledge it is connected to the battery, after 2 minutes it just goes into power saver mode which it's designed to do if you don't connet the charger to a battery. Any ideas why this might be?

I did try to connect the charger to my wifes Cruze which has a charged battery and worked immediately. Are these chargers designed to charge a dead battery?

thank you in advance

George

[Wonky]

I'm no expert but whilst these will help recover a flat battery I'd assume the results you're having would indicate the battery is not just flat but farked. Given it's only 8 months old I'd be taking it back for a new one.

get a multimeter and check the voltage of the battery, usually if the voltage is too low the charger wont recognise the battery.
simple fix is if you have a spare battery where the voltage is fine you can use some jumper leads to connect the two batteries, then after an hour or two just diconnect the jump battery.

As has been mentioned the battery needs to have at least 6 volts to reconise the battery. The cheat to get around this is to either jump start the car and connect whilst running and then turn off, the charger will then reconise or connect to another battery until it reconises it.

What happens if you manually put it into recondition mode?

[bush_basha]

what happens if you stick it on the supply setting where it's not the smart charger just a normally battery charger until it gets enough charge and then swap it back?
or as others have said trick it into thinking the battery isn't flat to bring it back to life

[QldKev]

The Ctek MXS 5.0 doesn't have that option. I would see if you can start it in recond mode, failing that I would get an old manual charger and give it a run on that for a few hours first, then swap it over. If that's not an option, even jumper cable the battery from a good battery until the charger gets to stage 3, then drop the jumper leads. I would definetly have it in recond mode.

if it's that flat , and you only have a mxs 5.0 charger , put it in motorcycle mode

[Fonz]

Thanks guys
Job done, I removed the battery from the car, gave it a small shake to make sure there was water in it, reconnected the charger and it began the recond process. I have no idea why this is. I did charge the Cruze for a couple of hours before I tried again, maybe there was enough charge left in the ctek to fire up the dead battery. I've left it on overnight and it's currently at stage 4.
Go Figure
For future charges if it ever gets that flat again, i'll piggy back it of another battery till it gets to stage 3. Now that i have the Ctek hopefully i'll never need to.

[Fonz]

Thanks XUV
The issue I had was the ctek wouldn't recognise it was connected to a battery regardeless of which mode i tried to charge it on, but all is well and charging as we speak. Thanks Toddler78 for the tip :)

[SICK SS]

Hi Peoples,

I came across these chargers a little while ago, but just recently looked into them alot more.
They are said to be the bees knees, the ducks nuts, etc, well you get what i'm trying to say. They say that they can be connected up to your battery without disconnecting from the terminals.

Has anyone on here got one & how do you rate it?
They aren't badly priced either, depending on where you look.

Thankyou.

i hav the 25amp/h ctek charger never takes more then 1 hour to start a flat battery

[Toddler78]

So time to dig up an old thread....

After my monaro ran flat again (due to only driving it every second weekend) battery had 3 volts in it.

I connected up my motorbike Ctek 0.8 amp for 24hr with no luck. So bought a MXS 5 off ebay for $69.99 delivered to my door.

Received it the next day

here is the link if any one is interested

Highly recommended. and great price

FYI - this model does have recond mode.

[mof]

I am on my third CTEK 15000. Use them to recharge jump start pack, boat battery and / or deep cycle battery for camping fridge. The first two were replaced under warranty, so I can't complain about them backing up their product, but two failures each less than twelve months means I can't give a great reference for the CTEK.

[C4B]

I've had 2 Ctek's die on me too. I've still got one in use but I think I'd probably go a different brand next time.

[GTS LSA]

I used one for 3 years on my GTO then a further 2 years on my EVO track car.... Still going strong

I've got one that is 4 years old that's still working perfectly too. But a failure rate of 2/3 is hardly confidence inspiring.

Looks like you got a good one too.....

[duke5700]

I was recommended a Projecta, 25amp so far so good. 6 months in at this stage. Previously I was using a battery charger I built myself, so its a little step up.

A CTEK MXS5, 2yr old .Which is plugged into my XUV 24/7 via an anderson plug, does what it does , batteries always fresh, no lag.

a Projecta AC250B , 5 yrs old,it works. which is plugged in to a HQ 253 Tonner paddock basher.

and I've got a solar charger screwed on to the side of my gator charging a 27ah gel battery, best 20 buck fix eva, battery always fresh

[Toddler78]

So to add to this thread.
On my motorbike I have used the eyelets and plug which hangs out just inside the fairing so I can easily plug it in. I have used the same for the Monaro but what I want to know is if others have done the same, where did you stick the plug out? Id like to be able to plug the charger in without having to pop the bonnet. Or can I wire it somewhere else like the accessory plug to charge the car?

[BigAnt]

I have a CTEK MXS5, only charger Ive ever owned but seems to be doing the job.
Ive done the same with my bike, and I just use the clips on the car battery with the plug just hanging out of the bonnet.
Not exactly sure what you mean by accessory plug but I think it would need to be hardwired to the battery.
Aren't accessory plugs only active what the key is switched to 'acc' or 'on'?

I too was wondering whether others just use the standard traditional clamps or do you use the special connector that permanently mounts to your battery terminals and just plugs in?

[monaro327]

I have the permanent connector and the end of it neatly sits behind the fuse box out of the way when not in use.

You can buy extra permanent connectors at Repco if you have multiple cars to connect to.

[clubzls2]

I have a trickle charger fitted to my motorcycle, it was fairly cheap< $50 and supplied and fitted by my dealer. I thought these can also be used on Cars, why would you want to pay a lot more for the Ctek any advantage ?

Hi

I have 2 batteries as standard in my AMG and have a CTEK connected to them so it trickle charges both batteries whilst they are still connected to the cars electrics.
In fact the CTEK charger is a an option for some new Maseratis and they also have no issues leaving the battery connected to the cars electrics whilst the battery is charging.

To Pickles: you will have no problem whatsoever doing this.

I also do the same procedure with a pwc and a boat.

hmm, seems your battery charge is dropping from 12.9, according to it's users manual .
check the battery a few times without charging, to see if voltage stays above 12.1, if so battery good.

Or maybe try it's recondition mode.

[decoupe]

The Battery reads 13.1 v without charger on it , but it just won't go past the stage 5 orange light when the charger is on it ?

I have just put the charger on the other car and it has now gone through the stages and is sitting on green at the moment ...

[XUV]

maybe it needed an " off and on " re set.

[Davothegreat]

maybe it needed an " off and on " re set.

I have a CTEK Lithium charger for the lithium battery in my bike and if I've let the battery drain too far (was around 6.5 volts last time) then it sometimes takes a couple of resets (read power cycles) of the CTEK charger to decide that the battery isn't faulty and that it can charge the battery.

Good charger though, takes no more than a couple of hours to bring the bike battery from seriously low up to full charge.
