  • Battery Tender Battery Chargers are designed to fully charge and maintain a wide range of vehicle batteries in ways that avoid the potential damage caused by other trickle chargers. All Battery Tenders share these five characteristics:

  • Fully Automatic At the end of a regular charging cycle, the charger automatically adjusts output voltage to a safe storage or float level, eliminating the need to always check a battery's status.
  • Full Output Power at Low AC Line Conditions Excluding chargers with 2 amps or less output current, full output power is delivered with input AC line voltages as low as 90 VAC.
  • Zero or Minimal Current Draw from Batteries When AC power is disconnected, most Battery Tenders draw no current from the battery. Some higher power models draw less than 1 milliamp.
  • Compact, Lightweight Construction At any given power level, Battery Tenders offer some of the highest charging power density in the industry.
  • Visual Indicators Chargers have some combination of colored lights to indicate charging progress.

    Rated 5 out of 5 by from Very satisfied far! I bought 4 about 2 months ago. 3 were placed on fully charged batteries and 1 on a semi-discharged battery. The three on the fully charged batteries, immediately went into trickle charge mode and have been that way to date. The other, on the semi-discharged battery, initially went into full charge mode and after about a day and a half, it switched to trickle charge and has been so since. So far I'm very pleased with the chargers and I'm quite impressed with the circuitry, switching from full, to trickle charge, as desired! Hoping to get many, many years out of the batteries due to the Battery Tenders, as well as, many, many years out of the Battery Tenders, too!

    Rated 5 out of 5 by from Works as advertised My wife originally bought me a Battery Tender for my birthday to put on our boat's trolling motor battery, which was occasionally discharged. It worked so well that I bought two more, one for my riding lawnmower and one for my boat's starting battery. Then I bought two more, one for my Suburban, which sets a lot, and one for my sports car, which I don't drive in the winter. All now have fully charged batteries whenever I need them. I am very satisfied with this product.
