This charger has a tremendous 200 amp assist start for really dead batteries. You have to be a bit careful because it doesn't shut off like an automatic. However I have used it on batteries that are older and don't respond well to a automatic, and letting it "overcharger" a bit and for certain it kicked new life into the older batteries. It feels like a real tough brute and I love it. I have several vehicles and tractors, Jeeps so it gets a real workout. Sometimes I let this charger do the tough work and then let it finish on an automatic, especially if I don't plan to be around to shut it off. Yeh the handle seems a bit whimpy but hasn't broken and didn't know how life was without it!! Great price on Overstock, especially if you are a member with cash rebate from a previous purchase and then free shipping with a holiday discount!!
