Re: Winter is coming -Battery Question?
Some people insist that removing batteries and putting them somewhere with a stable temperature, but NOT on concrete, is the only answer. I used to do that. Now I leave the batteries in and top them off by plugging in the charger about once a month.
If I had a solar charger, I'd leave the battery in and the charger on all winter. Just to be sure it's working, I'd check the battery with a float tester a few times.
Always be sure the battery is 100% charged before storing.
