I would highly recommend picking up a Ctek MXS5 or similar trickle charger/battery restorer. They have fantastic technology in them to desulphate the plates and extend the life of the battery. Can bring them back from the dead and keep them in good health if you aren't using your car for a while.

Can get an MSX5 on special for about $120 around black Friday or Boxing day from Repco. Or $150 standard price at PBTech. Could potentially pay for itself quite quickly with the extra life you could get from your battery.

Thanks apocalypso for the info. Had a known this I should have taken the old battery back with me when it got replaced. Maybe this is what AA does to their old batteries that's why they only last for 3 years. Will never ever buy AA batteries ever.

There is nothing wrong with AA batteries. They are definitely brand new. I believe they re-sticker one of the common brands like Exide or Century.

The Ctek is a brilliant charger for battery maintenance, one of the best chargers for leaving hooked up to batteries 24/7. I've owned several. However they don't fix worn out batteries. The desulphating technology simply assists in recovering batteries that have been left too low or flat for too long - that is all.

A worn out battery (ie all those that make it past the warranty period) is un-restore able, short of surgical replacement of internal parts. As a battery wears out, it sheds active material off the plates (Lead, lead dioxide & lead sulfate) which results in loss of capacity. Once too much active material has been shed from the plates the battery is mechanically and chemically kaput. neither a quality charger nor snake oil from the internet is able to take the active material out of battery sump and bond it back onto the plates.
