Battery Extender

The Battery Extender is designed to maximize the life of a serviceable 12 Volt lead acid battery. The Battery Extender keeps your battery at full charge on a continuous basis. Batteries not kept at a full charge become sulfated, which is the main reason for premature battery failure. Battery Extender should be used to charge and maintain all starting and deep cycle batteries in storage or that do not receive daily use. The Battery Extender is also fully compatible with gelled electrolyte (gel-cell) batteries (sometimes used in place of liquid electrolyte batteries in many heavy duty applications). The Extender is equipped with two different plug in lead sets. A set with ring terminals that installs permanently in your vehicle makes it easy to quickly plug the Extender in at any time. Also included is a lead set with battery clips. These are ideal for use on batteries not currently in use or that are in storage.
