Originally popular for winter motorcycle storage, the Battery Tender was soon discovered by tens of thousands of car, boat, snowmobile and lawn tractor owners who needed to keep a 12-volt battery charged and ready while stored.
The genius of the Battery Tender Plus is a microprocessor that precisely controls charging and storage voltage and amperage (up to 1.25 amps). Though it can recharge a dead battery in 1-2 days, its primary function is to keep the battery at optimum charge and extend battery life. Use its alligator clips or the wiring harness that can be attached to your vehicle. Reverse-polarity safety guard protects you from injury if it's connected backward. Available in 12-volt and 6-volt versions.
