The usual LA looses 1/2% (new) to 3% (almost shot) of its charge per day.
A fully charged batt will seldom freeze , but a dead one will.
The fact that AGM loose slower than LA makes them better for winter storage with no power for 5 or 6 months.
We have wintered with old LA with an 85W solar panel , that charges each time the snow melts , with no hassles.
Lots cheaper than an AGM , and with only a 135A truck alt faster charging doesnt come up.
