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

I like it a lot. I only have one complaint. The multiple lights that come on don't really add any value. The labeling on them requires a magnifying glass to read, and then it's a "So what?" The power cord is shorter than would be convenient.I give them major kudos for a tip in the manual. It advises that if the battery you are connecting to is depleted way down, you should connect a jumper battery to the problem one for a while so that at least some charge (>2 volts) can be detected by this charger. It worked, and I was able to resurrect a battery for my generator. I now have a spare and am thrilled!
