Most times this happens because of short drives not allowing the battery enough time to recharge. When was the last time you took it for a long drive with out starting it. Also a batteries life in these new computers on wheels is not as long as it used to be.

Nope. Either put on a maintainer or like take an hour trip or more straight without stopping to get SOC% up closer to 100 %. That trip is like twice a week if your battery has any time on it. My thought is to insure no issues and put on a maintainer sometimes. Even my battery gets to where the alternator is putting out like 14.9% volts to get SOC up, as I am just as guilty, and no, do not have a maintainer on ride. If I did not move truck once in a while, I would be leaning towards buying a NOCO to permanently mount under the hood.

OP U might even have a parasitic draw somewhere that not help.

All IMHO.
