Well it was about -30F in my garage yesterday and there are 3 batteries on trickle chargers. It is not unusual to have a battery charger hooked to a battery at these temperatures and lower. If I have a dead battery in winter I usually bring it inside but not always and unless the fluid is frozen or it is otherwise unserviceable they will accept a charge at very cold temperatures. My charger has low and high amp settings and an auto shutoff when the battery reaches full charge I usually start to charge at a low 2-4 amps and then increase the amps to 10 as the battery becomes charged.
The old fashioned way and the best way to test a battery is with a hydometer as O_D suggested IMHO.
