If not for my wife insisting that the dome light (door switch) fuse be pulled on her jeep (it also disables the headlight warning chime), he would probably still be using her OEM battery from 1999. She left the lights on one too many times. The battery didn’t fail, but started cranking the engine a bit slower. I just changed mine in my 02 not too long ago. As others here said, lots of factors. Trip length is what I’d attribute it to with my wife’s and my case. Longer operational minutes per cranking event. Heat is also a factor, more so than cold …at least from temp taken in isolation.
