Safe, 4-step Battery Charging
The Battery Tender Junior 12-volt charger is much more than a trickle charger. It has a "brain". Utilizing a 4-step charging program (initialization, bulk charge, absorption mode and float mode), it allows you to simply connect the charger to a battery, either in or out of a vehicle, and forget about it until you are ready to put the battery to work. Like all Battery Tender chargers, at the end of the regular charger cycle it automatically switches its output voltage to a safe, storage or float level that eliminates the need to worry about the damaging effects of overcharging, and the resulting need to check on the condition of the battery. If/when the battery voltage drops too far under load, output power resumes and the charging cycle begins again. The unit also features sparkproof connectors, short circuit and reverse polarity protection, an easy to understand charging status indicator consisting of a single LED, and almost no current draw from batteries connected to it.

*Note: All Deltran battery chargers will charge all types of lead acid batteries: either flooded (standard STD), sealed maintenance free Absorbed Glass Mat (AGM), or sealed maintenance free gelled electrolyte (GEL) batteries. However, for optimum battery performance in deep cycle applications (for example, running a trolling motor), it is best to chose the Deltran charger that has the charging software specifically designed for the battery type. Fortunately, since the technical staff at Deltran has developed charging software that works equally well for both STD & AGM batteries, the only choice to be made is between 2 models: either STD & AGM or GEL software.

Very nice product, 2010-03-08; By: A. Swierski(Phoenix, AZ)
This product has done everything it claims to do. My battery had gone dead over the colder winter months. This tender brought the battery back to charged level and is maintaining it until I can purchase a new battery.

Own Seven, 2010-02-26; By: David Paul(New Hampshire)
I personally own seven and very satisfied. They are easy to use on any battery, snowmobile, 4 wheeler, car ect. and the best part is they do not over charge the battery.

THE BEST CHARGER/TENDER EVER!, 2010-02-22; By: Linda C. Palmer(Birmingham, AL USA)
I purchased a tender for my bike and liked it so well I bought two more. One for my brother-in-law and one for my sweetheart. The easy connect to the battery was wonderful, plus the quick clip for disconnecting from the charger is even better. It's a quality built item and I'm sure I'll have years of great service from it.
I'm really looking forward to giving the Tenders and watching the faces when they see how easy it is to install. My brother-in-law's battery is located under his seat, so he has to take the seat off and the battery out to recharge. So he'll really appreciate the easy connect and quick clip. I would definately recommend this item to anyone.

Keeps my motorcycle alive and well!, 2010-02-22; By: Skai(SF Bay Area)
LOVE this thing! I no longer have to worry if my motorcycle will start or not.

I permanently attached the leads on my battery so the small connector is tucked in my front grill. When I park my bike, I just plug the connector to the Battery Tender and it's all set. Takes me about 5 seconds. No problema!

Totally worth it.

LOVE IT, 2010-02-19; By: Michael Adler(Las Vegas, NV)
This is a great product. I bought two, one for my brothers 2009 BMW R1200RT and one for my 2009 Harley Davidson Ultra Classic. I installed the harness on both bikes in just a few moments; it tucks neatly away under the frame. The quick connect is easy to close off with the include cap and easy to open back up. The leads are long enough and it charges well. I like the lights on the front that give me an instant view of the battery condition. Price is right too at about $24. I highly recommend this unit for anyone with a motorcycle.
