I would remove the battery and bring into garage or inside. Set up with a trickle cell charger ( cost about 20-30 dollars, can buy pretty much anywhere, Walmart, Hardware stores, etc.)

You can also use a low amperage ( cheap) solar cell panel for your battery- as a TRICKLE charge only. Don’t expect this to “charge your battery for you..
