So in Frigid Canada , it gets down to about -40. At about -15 i noticed my car would not start unless it was in a heated garage anymore. took it to the dealer, said the battery was low , but they charged it and tested it OK. After the same even happened several times, the battery was replaced , it starts in -32 right now. the manual states using my heated seats may weaken my battery, in these temps i want them on 24/7. So Would a bigger battery help? is the alternator too weak to sustain its own factory electronics? dosent seem to make sense to me. Does anyone know the Alternator amp rating it is a 2007 2.4L EX-L All help is appreciated.

There are batteries in your original equipment size, that have different capacity. Shop around, and find the one with the most CCA (Cold Cranking Amps) and "Reserve Power". I bought a battery from Sam's Club for 45$, which had more power than the original battery on my 03 V6 Accord.
