Rated 5 out of 5 by Good product Like it good product August 16, 2016
Rated 5 out of 5 by Works great! Great value, works very well, Unit is automatic and requires no learning curve. Great for long-term battery maintenance for my rare, classic, BMW Z-4 which is only occasionally driven (Sunday afternoon country drives). A real necessity, as the 640-cold cranking amp "special" application Z-4's battery costs $260.00. Car / Motorcycle Collectors: A MUST, GET ONE! July 27, 2016
Rated 5 out of 5 by Dependable, works. I've been using these on my motorcycle and boat batteries for many years. Never had a problem and they extend the practical usage of the battery's life expectancy. Although they cost a little more than some brands that I have purchased, they outlasted them all.They pay for themselves in a short amount of time. June 25, 2015

Rated 5 out of 5 by easy to install Works great...easy to install..good value December 26, 2014
Rated 5 out of 5 by Battery Tender works very well I have two of these. Great for keeping the car battery at top charge. Especially good for very cold nights. Your car will start right up if you use this overnight. Also good for lawn mower battery over the winter. December 15, 2014
Rated 5 out of 5 by Works as advertised Great product! November 4, 2014
Rated 2 out of 5 by Not For Me While I'm sure the unit works just fine, I returned it because it needed to be attached to an electrical outlet, and I wanted a gadget which could be charged and brought to the car independently. Item description was unclear about this. February 13, 2014
