I've had my Schumacher SE-1-12S / 1.5 amp battery charger for several years now with no issues or complaints what-so-ever. In fact, I have several for all my vehicles, including my Motorcycle. First off, they are one of the best chargers out there. Durable and resistant to all weather conditions. Hook up is easy and with this model, you can permanantly mount it to battery, fender,or firewall. Keeps battery charged at around 13 volts. Automatic float charge when battery is full. Schumacher has several models of this type charger. I have used them all w/ the same results: Best product for the money. Recommend this model and all Schumacher battery chargers and products. 5-Stars!!!
