BATTERY TENDER PLUS

The Battery Tender is a 1.25 amp battery charger that automatically switches from full charge to a float charging mode, and then monitors the battery. When the battery is accepting only 0.5 amps, the Battery Tender switches into a float charging mode. At this point, both the current and the voltage are held at 13.2. The gassing point of a battery is 13.8 volts, therefore applying voltage greater than 13.8 for an extended period of time will damage the battery. Trickle chargers decrease current, but increase voltage to upwards of 15.5 volts, and continue the excessive gassing action that is most detrimental to the life of batteries.
