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.

    I concur. Get the alternator checked. The diode might be giving up the ghost and causing reverse-current, draining the battery even while off.
