View larger. | 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. Key Features: - Perfect for all lead-acid, flooded or sealed maintenance free batteries (AGM and gel cell).
- Complete 4-step charging program (initialization, bulk charge, absorption mode and float mode).
- Automatically switches to float / maintenance voltage after fully charging the battery.
- If the battery voltage drops too far under load, full charger output power resumes.
- Solid state two color LED indicates stage of charger.
- Spark proof and reverse polarity protected.
- 12' output cord.
- 5 year warranty.

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. | Five-year Limited Warranty

Warranty is void in cases of product misuse, disassembly or modification.

 Good Value September 7, 2010
Dewbob
Other than the slow shipping by Amazon, everything is good with the charger. The automatic shut off is a great feature in a small charger. You can leave this charger plugged in and it will keep the battery at maximum charge.
