E150 Electric storage

[jwax]

New-to-me Craftsman E150 Riding Mower is getting stowed for winter. Any advice on battery maintenance over winter? It's a Li-Ion battery, so is it best to leave it on the charger, or just periodically charge it during freezing temperatures?

Li batteries don't like being continuously charged. I would say top it off if you are done mowing for the season. Take it inside your crib for the winter. Top it off in the spring. Mow as normal.
