It uses a 4-step charging program and is spark proof. The Battery Tender Junior Charger comes with a 12-foot output cord and allows for maximum optimization of battery power, without overcharging.

    Rated 5 out of 5★ by If It Holds Up It's An Incredible Deal! I've owned numerous battery chargers in the past and most, even famous brand named chargers, don't last long anymore.This is my first "maintainer". After reading up on this one all over the internet, I decided to take the plunge and the price at Walmart was the best anywhere.I have a 98 Dodge Grand Caravan with a 3.3 liter engine and it sits for long periods of time between use. It takes some juice to crank that thing and after sitting for weeks or more the battery in cold weather can drop to below crank level. I can always jump it but thought I'd try the Junior Charger. I'm happy to report that since using the Battery Tender Jr. I've not had to jump the van once. The van starts right up on first crank!I went ahead and used the battery clamp mount which has a non-shorting plug that sticks out of the grill at just the right place and length. When I need to use the van, I just unplug. When I drive back into the garage, I plug it back in, all without having to open the hood.So far, the device has worked perfectly and as the title implies, if it will last, it is an awesome deal. I also used the Site-To-Store option which took about a week, which was fine for me. 03/14/2014
    Rated 5 out of 5★ by Plugged it in and it worked great. I'm retired now and don't drive much, so my battery goes dead from one week to the next. This is my second Batter Tender. I like the fact that the light turns green when you have a full charge, my old one didn't. Also this one is better made and more sturdy. 03/16/2014
