I have heard that the battery in VE Commodores cannot be charged without a special charger? Is this true? I have just spent a month away with work and now it appears that the battery is dead. It was driven once by my wife whilst away, and I took it out this morning with no issues, but this afternoon whilst I was in the shed doing some stuff and had the radio going it just died (whole car went black). Is the battery stuffed? I have CTEK on it at the moment, and have got it started again, but thinking I might need new battery?
