Battery Tender
All Battery Tender battery chargers are designed to fully charge and maintain a wide range of styles of lead acid batteries in ways that avoid the potential damaging effects that can be caused by most trickle chargers. All Battery Tender battery chargers have the five following characteristics:
•Fully Automatic: At the end of the regular charger cycle, every Battery Tender battery charger automatically switches its output voltage to a safe, storage or float level that eliminates the need to constantly check on the conditions of the battery.
•Full Output Power at Low AC Line Conditions: Battery Tender battery chargers will deliver full output power with input AC line voltages as low as 90 VAC. (Excluding chargers with output current of 2 amps or less).
•Zero to Minimal Current Draw from Batteries: When the AAC power is disconnected, most Battery Tender battery chargers draw zero current from the battery. A few of the higher power models draw less than 1 milliamp from the battery.
•Compact, Lightweight Construction: At any given power level, Battery Tender battery chargers offer some of the highest charging power density in the industry.
•Visual Indication of Charge State: Every Battery Tender battery charger has some combination of colored lights to indicate the progress of charging.

Charge and maintain your 12 V batteries with the only line of battery chargers equipped with all these features. With Battery Tender, you can’t go wrong.
