The battery isn't at its best at cold temperatures but I would say that it's a combination of not addressing poor starting, not monitoring charging and folk not understanding that using electrical loads with the engine off has a surprisingly high drain will kill a battery prematurely.

Small things can make a big difference too like popping the door latches and not having the radio on when hoovering your car.
In my parasitic drain test video, you can see how easy it is is to increase battery drain just by unlocking the car and "waking it up" so the longer it's in that state without the engine running, the faster it will discharge.

I also have a smart charger so maybe twice a year around summer and Christmas, I'll give the battery a full recharge off the car which can take up to 24 hours.

A battery is a bit like a leaking bucket and how you use it determines the size of the hole.
