Battery Tender Jr 12V is rated 4.8 out of 5 by 21.
Rated 4 out of 5 by from Works as advertised - a long term investment. These units differentiate themselves from units half the price in the quality of the case, leads, and the permanent leads with the connector. Other cheaper units have the same logic, cheaper cases, no connector to move between permanent and clip on leads. More expensive products claim to "desulpher" the plates, but given the limited life span of a lead acid battery, why spend the extra money? This is a well packaged product that I can expect to last a long time. It can survive being stepped on (oops) and will outlast the less expensive units I referenced.

Rated 4 out of 5 by from Works as expected Purchased this for my Corvette when it's put away for the winter. I like that it came with clamps and ring terminals. I put the terminals on the tractor and use the clamps on the car. The quick disconnect makes it easy to use on two batteries without having to remove the car cover and open the hood to remove.

Rated 5 out of 5 by from battery tender JR 2nd one of these I've purchsed( this was was a gift to my nephew while his bike is stored when he goes over seas). As good as the next expensive model, maintians charge, is convenient and reliable. Cheaper than a new battery, well worth the price.

The clips on the charger are rusting? Why? And what can I do to stop the rust?

Asked by: Nanc
We have never seen these rust. They may have been subjected to moisture at some point. Try lightly sanding the rust off and keeping out of a high moisture environment.

Asked by: Dana
Hello, Unfortunately this will only be good on lead and acid batteries.
