Battery Tender Junior
12V @ .750MA
The Battery Tender Junior battery charger is the small and simple solution to the challenge of keeping batteries optimally powered while not in use.
Ideal for Motorcycles, Lawn Mowers, Jetskis, ATVs, and Vintage Automobiles.
Only Charger brand on the market with ISM Technology ( Infitinite Sequential Monitoring).
Smart Charging Made Easy!
The Battery Tender Junior allows you to connect the charger to a battery (either in or out of the vehicle) and forget about it until you are ready to put the battery to work. Like all Battery Tender chargers, once the battery has reached a 100% charge the Junior automatically switches it's output voltage to a safe, storage/float level that eliminates the need to worry about the damaging effects of overcharging. If/when the battery voltage drops too far under load, output power will begin again bringing you battery back to a fully charged state.

- Spark Proof
- Reverse Polarity Protected
- Short Circuit Protected

But let's first get back to basics: what is a float charger, and why is it needed?
Lead-acid batteries, of the type used in cars and motorcycles, lose a part of their charge over time just sitting when they aren't even connected to something. When left in a bike that has a clock or radio memory circuit in it that constantly draws power even when the bike is off, that loss of charge is even faster.
Lead-acid batteries "like" to remain at full charge at all times. A battery that is kept at full charge will have a much longer service life than a battery that is left sitting with less than a full charge.
I used to go through a lot of batteries - my motorcycle batteries would last between one and two years before they needed replacement. With multiple motorcycles (not to mention other battery powered things like a generator, snow blower, etc.) this gets expensive!
I figured I would put a trickle (float) charger on my main GL1100 battery to help keep it fully charged. I bought a cheap trickle charger from Harbor Freight, for under $10. I hooked it up to the battery and left it sitting overnight. The next day, to my utter surprise, the battery was dead! The cheap trickle charger, with no intelligence in it and no way of turning off when the battery was charged, overcharged the battery, destroying it!Read more ›
Based on my prior experience, on November 4, 2010, I bought another Battery Tender Jr. from Amazon for another infrequently driven car. It is now less than 1 year later, and that Battery Tender Jr. got so hot that the plastic case buckled and separated at the seam. So, planning to return it under warranty, I read their terms. Not only do I have to pay to ship that defective unit back to Deltran (which I expected), they also charge a fee for "Warranty Evaluation, Shipping & Handling"! That is OUTRAGEOUS! Since I have my receipt, my fee would be only $7.95 (if no receipt, fee is $11.95). It would cost me $18.90 ($7.95 plus $10.95 USPS Flat Rate medium box) to return it (or $22.90 if I didn't have a receipt - which is more than the $21.39 cost of a new one from Amazon delivered!) Why bother with a warranty claim? If that was Deltran's plan from the outset - to discourage warranty claims - their so-called "warranty" is a fraudulent misrepresentation.
No doubt that my first, 20-year old Battery Tender Jr. was made in the USA. Not so with the second one - the label says "Made in China". A piece of Junk!
