Review on Efficient Charging With LST 7 Stages 5A Battery Charger - 3.3A 12V For Ultimate Performance by Carlos Whitfield

I bought it to charge an rv (marine) battery. My rv is in storage and will eventually need a new battery, because it can't hold a charge. Right now, I am renovating it, so I occasionally go down and need to use the battery to extend and retract the slides. I keep the battery at home and charge it up before going down to the rv, then bring the battery back with me.
