AutoSport Battery Charger/Maintainer

Storing you car for the winter? Keep the 12-volt battery charged and ready for spring with the AutoSport Battery Charger/Maintainer. An advanced microprocessor controls a 3-stage progressive program: it begins charging at up to 1.25 amps, and when the battery is fully charged, the unit switches to a "storage" mode that can dramatically extend battery life. Use the included alligator clips, or permanently attach the quick-disconnect harness to your battery terminals. Won't damage your car (or itself) if you accidentally reverse polarity. It's also great for motorcycles, lawnmowers or boats. Durable aluminum case is 3-1/2" x 3-1/2" x 4".
