Not driving enough?

[kymts]

Hey. I am asking about my 2022 Ram hemi with eTorque. Has just over 2,000 miles on it and stays parked inside with a battery maintainer on it.
The 12v battery looses charge quickly. Should I replace the12v battery or just drive this truck more? When I do drive it is just a 7 mile round trip to pick up gardening supplies.
Thoughts about the 48v unit or other suggestions? Autozzome tested and said the battery was good and just needed charging? I drove home and hooked up the charger.
I just checked the battery maintainer/charger 2 amp unit. It was still charging since yesterday and was up to 14.5v but still in the red. I opened the truck door, popped the hood , looked at the charger again and the voltage had jumped down to12v in just seconds. Replace the battery and if so with agm?

Sounds like a few dead cells in the battery. I put an AGM in my 20 but I think they come with an AGM battery

Here is some reading material. Walmart AGM price and warranty is pretty hard to beat.

Robot or human?

Def need to drive more. Cars and trucks don’t like to sit. They do better when used regularly and taken up to operational temperature each and every time. Never short tripped. I have a similar situation as the OP: we have the truck left after selling the RV. Now have little use for a truck. But I do so love driving it. So, I do drive it. Whether I’m going anywhere or not. Take the truck out and put 25 good Highway miles on it. Then park it for a couple days, no more.

The guy who ends up with my 2021 Hemi will love that I never short tripped this truck.

Agree! I had some problems with my father's and father in law's car batteries from lack of use. From what I recall from my research 20 miles of highway driving once a week is needed to keep the battery charged up. Battery tender is good for the battery but does nothing for the brakes rusting, flat spots on the tires and I'm sure other issues.

Thanks for the responses. I went to Autozome and had them install the Platinum AGM battery as many on this site suggested. Thinking this will be the solution for short term and driving the truck more for the long term. I think BowDown was spot on with the dead cell theory as my pulse charger finally got the original battery back to the good but it still acted weak by loosing amperage quickly.
