The Battery Tender Junior battery charger is the small and simple solution to the challenge of keeping batteries optimally powered while not in use.
The Battery Tender Junior allows you to connect the charger to a battery (either in or out of the vehicle) and forget about it until you are ready to put the battery to work. Like all Battery Tender chargers, once the battery has reached a 100% charge the Junior automatically switches it's output voltage to a safe, storage/float level that eliminates the need to worry about the damaging effects of overcharging. If/when the battery voltage drops too far under load, output power will begin again bringing you battery back to a fully charged state.
