Review on Maximize Battery Life: Battery Saver 2365-24 24V 50W Quick Charger with Auto Pulse Maintainer by Bob Vulpes

I have a lift that uses 2-12v batteries for a 24v system. It has an onboard charger but it's all or nothing to charge. Has probably cost me several sets of batteries over the years. It has a maintenance function so we can leave it plugged in all the time and always have a fully charged system without all the liquid boiling off.
