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

Great little battery charger so far, except for one thing.I'm using it to charge and maintain my 12 volt emergency sealed battery for my GoZero lights and USB power source.I love the various hook up cords, that gives me a lot of flexibility. I love the various batteries that it will charge up. so it's always ready to go.It gives me piece of mind that I can leave it plugged in full time so it's always ready to go.There's just one problem. if you live where their are lots of trees that touch the powereline's in a windstorm and flicker the lights or take the power out. My unit went into a special Desulphation mode and started draining the battery. I had to completely unplug the unit from the battery and Elec outlet, let sit for 5 min and then plug back in to get it to work.
