Battery Charger, 12V Auto

Keeps your 12-volt battery fully charged without over charging

This float charger is designed to prevent the normal discharging of a battery that is not used for weeks, months or years. By keeping the charge up, the tender extends the life of batteries rated for 5-125 amp-hours. The tender can do this by providing a constant, minimum current, regulated output, which is great for long-term use. The float charger works on all 12-volt batteries for cars, trucks, motorcycles and boats. It comes with a 1-year limited warranty.
