    The Battery Tender Junior Charger is much more than a trickle charger. It is lightweight, compact, fully automatic and very easy to use especially in small spaces. The car trickle charger chargers offers ideal solution for keeping your vehicle batteries optimally powered when they are not in use. Whether it is a lead-acid battery, including standard and sealed AGM and GEL Cell battery types or any other kind, the 12v Automatic Battery Charger can be used to charge them all. 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. The 12-volt battery charger is eco friendly and an excellent mean of ensuring that your battery is fully charged throughout.

    Battery Tender Is The Best

    Customer review by Leprachan

    5.0 stars by Leprachan

    I have been using a Battery Tender many tears for my Harley-Davidson to keep the battery fully charged year around. I bought this Battery Tender Jr. for my John Deere tractor to keep the battery fully charged on a year around basis. Batteries last so much longer when they do not have a major swing in there charge. Great thing to have if you want to make sure you always have a full charge. Great for even storing your vehicle over the winter and not have to worry about a frozen battery or loosing all your electrical settings.

    I own three of the Battery Tender line of products. This one, to keep a back-up battery for my whole house generator ready for duty & two other units (a waterproof 800 & a Power Tender). The other two keep my RV chassis & coach batteries fresh when the RV is not in use. All the Battery tender units work great & keep the batteries in "like new" condition.

    • I had an old Jeep that was parked outside all the time and run infrequently. I was jumping the battery every time and tried the battery tender jr. on it. It took a couple of days but charged the battery up and refreshed it. Still would drain after a few days without running it but kept me going for another year.

    • No, the BT Jr is NOT a charger, it maintains peak levels. Batteries have a small drain due to things like clocks, stereos etc. if the car/motorcycle sit for a long period of time the BT jr keeps the battery fully charged. Whether in the vehicle or out of the vehicle. Works great. My car sits for several months due to the cold weather so I keep it plugged in for several months at a time.

    • Not sure what you mean. If you have a bad battery you must get a new one. This will not fix it. Google, what does the lights mean on a battery tender jr. I believe it will indicate a bad battery by the way the green and red indicator lights do, flash etc.

    • If the battery has failed the indicator lamp will reflect this and the battery will not charge

    • Doubtful. Try it to see if you can get any charge into the battery with the tender Jr. It might put enough of a charge (if the battery is totally dead) into it to get your full size charger to charge it. This may take a couple of days on the Jr.
