..........My outside batteries are trickle charged once a month, the rest are stored in the garage and trickle charged a couple of times every winter. Seen to many battery fires to leave a trickle charger on all the time.
I use a receptacle timer like those used for engine block heaters. Trickle charger timers are given just a couple hours per day to charge. Works like a charm.
