Battery Charger

The World's Most Advanced Battery Charging System Designed For Today's Batteries

Battery Tender

The "Original" Battery Tender

  • Fully charges battery automatically
  • Maintains full charge indefinitely
  • Outperforms any standard charger
  • Cannot overheat or overcharge
  • Five Year Warranty
  • Designed and assembled in the USA

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 voltage of the Battery Tender decrease. The current drops to 10 ma. (virtually no current) and the voltage is 13.2. The gassing point of a battery is 13.8 volts; therefore applying any voltage greater than 13.8 for an extended period of time will damage the battery.

Trickle chargers decrease current but will increase voltage to upward of 20 volts and continue the excessive gassing action that is most detrimental to the life of batteries.

Available in 6, 8, 12 and 18 volt models. Comes complete with quick connect cables, alligator clips and ring terminals.
