Keep the batteries of all your vehicle fully charged with the Battery Tender Plus 021-0128 12V Battery Charger. Equipped with temperature compensation feature, the charger maximizes charge voltage on the basis of ambient temperature. The Battery Tender Plus Charger is convenient to use and includes a host of features. The item not only charges the batteries but also switches to the float charging mode automatically after the charging cycle is complete. This lets you avoid overcharging and keep your batteries safe. Enhancing the safety of this vehicle battery charger is its reverse polarity detection feature. It indicates if you set up a wrong connection by flashing the red and green lights alternately.
