My car sometimes doesn’t get driven for a week at a time, between that and winter cold I am having constant issues with it dying and needing to be trickle charged. My engine also seems to want a lot of juice for it to turnover.
Would an AGM battery last longer between charges? Would it perform better in the cold? Is there any better solution than just making sure some regularly drives it a few times a week?
Edit: It seems Costco lists an AGM for my car cheaper than a lot of regular batteries, so it seems like I will find out either way… But I am still curious if people think this will solve my charging problems.
Don’t waste your money on an AGM battery. Unless you have a premium luxury vehicle (i.e. Audi) and the extra cash to burn, just find a decent brand battery with as much CCA as you can fit under the hood.
Get yourself a 12V trickle charger. Most quality units will fully charge your battery and keep it in a “floating” mode to top it off, letting you keep it connected to the car for several days at a time.
Why does the car being permium matter?
It seems an AGM battery does have the highest CCA that the websites list.
Its a 40-$50 difference between the highest CCA regular vs AGM.
