Bests & Worsts Reviews from Amazon

Stay far, far, far, away from this charger. I walked away from tested, good, low charge battery being charged on the 8amp setting connected to a 750CCA regular car battery and when I came back a couple hours later it was boiling and still trying to charge! I checked the charge voltage and it was at 16 volts (measured with a Fluke meter)! Bad, very bad, charger and not automatic or smart at all.
