Everybody is hooking their batteries up to these trickle chargers and leaving them. That is not the same thing as charging the battery once in awhile. If you ride once a week you don't have to charge a battery. If the battery gets a little low a battery charger hooked up for an hour or two will charge it. It doesn't have to be plugged in 365/24 which is what people want the little chargers for.
I think Wirewrkr has 6 years currently on a Toyo battery? Or was it 5?
