I might plug it up twice a week for a few minutes each time as I walk by the bike. If I forget and leave it plugged up overnight...oh well! I'll just unplug it as I leave for work in the morning.
The bikes are in storage and the batteries are on chargers in the (ventilated) basement. It's a little inconvenient, and I might forget, but I think I may try that.
By the way, I notice that the AGM battery from my Honda CB360 charges much more quickly than the flooded battery from my S40, and they are about the same age with similar output ratings. I wonder if that means anything?
