Batteries need 'maintenance'
As alluded if you you fit and forget then they will 'drop off' regardless of price.
Problem is they can sit around for weeks and then the capacity may have dropped down so when you do turn up for a quick whiz about (and have done a walk around that checks every mortal system) 'that requires power on' by the time you go for a start it will struggle and possibly lead to a carb fire.
Depending on your 'parking/hangar' situation a simple solar charger may be an option but the truth is lack of use is not good and that goes for the engine.
Also it is not unusual for pilots not to know about the the need for 'pre heat' when the temp falls below a certain level. The engine/airframe manufacturer usually have a section about that in the handbook and it not surprising when you consider how much effort it requires to 'churn' the oil around in a stone cold donk.
When I had to operate a C180/182 in the winter (parked in the open) I found that 15-20 mins with a fan heater directed from below via the cowling gill (and possibly with temp muffs in the air intakes) made for an instant start and of course in the real cold weather flying world 'oil dilution' may be an option.
Batteries are like your health ' YOU have to look after it' !!!
