Review on Luoges Automatic Battery Charger and Maintainer: 12V 6A / 24V 3A - Smart 7-Stage Automotive Trickle Charger for Car Battery, Motorcycle, Lawn Mower, Truck, Lithium, Lead-Acid, LiFePO4 - Yellow by Daniel Jackson

Bought this to charge my son's electric jeep, worked great until last week. It shows that it's charging and that it's reaching 100%, but it's not. I tried it with a different battery to be sure it gives the same result. The return period is over so I guess I'm stuck buying another charger or using the Sears car monster.
