Solar battery charger/ tender
 

Thinking about picking one up. Anybody use them? Can any body tell me if they are any good or a particular one to buy?

I have a solar charger on a 10ft fiberglass skiff connected to a lawn mower battery.
That battery runs a small bilge pump I recessed into the floor.
Going on 4 years, the battery is always fully charged.
