Battery Tender Plus

A small portable battery tender for power on the go.

I’ve been told - and you probably have too - that exercise gives you energy. Long periods of inactivity make us tired and sluggish. Car batteries work the same way. If you don’t use them, you lose them!

Letting your vehicle run for a few minutes periodically will restore power to your battery, but vehicles that are stored over a prolonged period may not get any exercise. The battery slowly fades because it never has the opportunity to recharge. Plug your vehicle’s battery into a Battery Tender Plus and you don’t have to worry that your vehicle won’t start. The battery will be as fresh as it was during your last Sunday drive, no matter how many Sundays ago that was. (If only Deltran made battery chargers for people!)

The Battery Tender Plus weighs only 2.7 pounds, making it ideal for the trunk, the boat, or even your motorcycle. It is waterproof, shock resistant, and vibration resistant so it can withstand rough waters or off-roading. Take it with you so you can charge your battery anywhere there is an AC outlet. The Battery Tender Plus charges any size, flooded or sealed maintenance-free lead acid batteries. The float mode maintains the proper voltage of a battery at all times, without the damaging effects of trickled chargers. The reverse polarity protection keeps you from damaging the charger by incorrectly attaching the alligator clamps.

The BatteryTender Plus is compact, easy to use, and incredibly durable. Keep all your batteries alive and well with the Battery Tender Plus.

  • NEW DIAGNOSTICS! Red & Green Lights Alternately Flash for Reverse Polarity or when the battery is sulfated or if the battery terminals are corroded.
  • Temperature compensated to ensure optimum charge voltage according to ambient temperature.
  • Automatically switches from full charge to float charging mode.
  • Battery Tender at 1.25 amps will charge as fast or faster than any 3 amp charger available.
  • Reverse Polarity Protection to ensure user safety.
  • Complete 3-step charging program (Bulk Charge, Absorption Mode, Float Mode).
  • 10 year Warranty!

    Durable, works great
    Got this as a gift in 2001. Its still working great, I use it on my boat right now. It's been dropped numerous times, had rain sprinkle on it, and been carried all over the country, and still works like a champ. The small size is great. Highly recommend

    Works just as it should
    An excellent product so far. Well built, intelligently designed, and simple to understand legen directly on the back of the unit to tell you what the light displays mean.

    My car has side post terminals and the ring terminals are too small to fit. I use the aligator terminals but the heads of the bolts in the batteries cables are very small and not a very good fit using the aligator clips either. They should mention that this will not fit some cars/batteries. My car is a 2001 Pontiac Firebird.

    Great little chargers
    These really work great. Have had one now for a couple years that we use on the RV battery and am getting another one for our car. Just plug in and forget them.

    attery Tender Plus
    Excellent. I only put about 100 miles a month on my92 legend with multiple aftermarket amps. Keeps everything fresh; battery doesn't burn out in 6 months as prior to using it.
