1. 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.
   
   
2. 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).
   
   
3. 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.
   
   
4. Compact, Lightweight Construction:  At any given power level, Battery Tender battery chargers offer some of the highest charging power density in the industry.
   
   
5. Visual Indication of Charge State:  Every Battery Tender battery charger has some combination of colored lights to indicate the progress of charging.

Battery Tender battery chargers offer a variety of power levels: 7.5, 15, 70, 300 & 600 watts, maximum charge currents: 0.75, 1.25, 2, 3, 4, 6, 10, 15 & 20 amps, and nominal battery voltages: 6, 12, 24, 36 & 48 volts. Various charging algorithms are available to accommodate the wide range of lead acid battery styles: Flooded, Sealed, VRLA, GEL & AGM. Check with the factory for the combination of power, current, voltage and battery style that best meets your needs. Battery Tender battery chargers are equipped with a variety of safety and interconnect options, not available on all models. Safety options include: spark free operation, reverse polarity protection and continuous short circuit protection. Interconnection options include: alligator clips, fused ring terminals and quick disconnect DC output cable harness. A variety of AC input power options are available.
