What the hell good is a sump pump battery charger that you have to
plug in and unplug? It's not as if there's never been an automatic
charger invented, either.
Though I don't see the point of a backup battery; it won't have enough
lasting power if you need it (there's a very narrow range of flood
sizes that it will help you with, most being either too small - so
you don't need the pump - or too large - so the pump buys you five
minutes and then the basement floods anyway. It's conceivable that
there's a perfect-sized flood on the way, not too small and not too
large, and you will look like a genius, but I doubt it).
