Replacing battery

[OzJavelin]

My '03 SV8 is starting to struggle starting .. not too bad, but I don't want my wife stuck somewhere @ night with a dead battery. If I replace the battery myself, what electronic "stuff" will be lost when the battery is disconnected? The car is running fine at the moment and I don't really want it to change it's behaviours because it's re-learning everything ...

Is it just easier to get auto-elec or dealer to change it?

all you will have to do is put the pin code in the stereo to unlock it

Not certain, but perhaps reset the clock also? :)
Your PCM does not matter and your trip computer does not matter.

Two ways to do it remove Battery retainer & swap Battery over with the new one as quickly as you can.
Or use secondary Battery eg a 12V gell cell with a pair of small alligator clips attached to your existing battery leads whilst changing the Battery's over ensuring not to ground out or shorting the terminals. This way there will be no memory loss from radio & PCM etc.

And reset the time!!! =)

Don't bother with an Auto Elec, It will be a waste of money.

Mate I changed my battery exactly as VY Tonne suggested and lost absolutely nothing. Very easy to do yourself otherwise the battery people sometimes charge.
Have fun and make sure you change you battery straight away it is common for them to die all of a sudden,

Many's the time that's been the frustration of a young woman on her own...:nyuk:

Mate, I just went through the same thing, change your battery ASAP and do it yourself, all I had to do was reset the time/date. Didn't need any PIN codes or anything.

Replaced battery in my maloo today and every thing worked and turned on when i turned the key. Didn't need codes for the radio or need to reset the clock.

Replacing it is simple and does not need an auto electrician. Make sure you buy a genuine ac delco battery or one that is designed for your car as some of the larger capacity batteries of around 560 CCA (cold cranking amps) are too tall to fit under the bonnet without a little arc welding taking place :bawl:
It really does not matter how long the battery is out before it is replaced but try to minimise the down time. Once the new battery is installed, start the engine and let it idle for about 10 minutes WITHOUT touching anything eg, ac, steering etc.. This will give the ECU a chance to relearn the base settings and it will learn the rest as you drive. As mentioned replace it NOW if it is showing signs of dying as they can fail quickly and usually do so at the worst possible time especially now it's getting colder. Allow about $100 give or take for a new one but shop around. Keep the invoice for any future warranty claims within the 3 year period from new (ac delco warranty). Last but not least, apply a terminal spray on the terminals to prevent any unwanted corrosion forming. As a general rule, whenever a battery has been allowed to go flat and is recharged, it takes a good chunk of life out of it.
Good luck ;)

My 1000 CCA battery fitted fine. battery models differ from size, not CCA alone.

vz models hold the codes in memory

Very true 6L.club, I merely mentioned it as some suppliers don't take in to account what it's going in and sell a battery physically too tall. How much did the 1000 CCA set ya back and what brand is it ?

[6.2L.Club]

From memory it was about $350, and the labels fell off of first time l hit it with a pressure cleaner so l can't remember the model/brand. I had issues with that car with the battery draining from an electrical fault in the door locking mechanism but every time it recharged fine and was still going strong for the 2 years it was in the car til l sold it.
Got it for my car stereo install ($20K worth) and only ran a single battery with a 25 farrad capacitor. Worked a treat, Even though the stereo was capable of drawing up to 250 amps flat nakka in comps.
Got the battery from Alberts Car stereo (www.carstereo.com.au) in WA.
