| The Battery Tender 12-volt/1.25-amp 4-Bank Battery Management System is designed to fully charge up to four 12-volt batteries simultaneously and maintain each at its proper storage voltage without the damaging effects caused by some trickle chargers. Compatible with all AGM (absorbed glass mat), sealed maintenance free and flooded batteries commonly found in some automotive/farm equipment, motorcycles, ATV’s, and personal watercraft, this lightweight, microprocessor controlled unit provides safe, constant, four-step charging current for every vehicle stored in your garage, shop, barn or boathouse. |
Safe, Smart, 4-step Battery Charging
| Simultaneous charging of four separate lead acid battery batteries, including AGM and gel cell. |
| The 4-step charge cycle detailed. |
The Battery Tender 12-volt/1.25-amp 4-Bank Battery Management System is much more than a trickle charger. Utilizing a 4-step charging program (initialization, bulk charge, absorption mode and float mode), it allows users to simply connect the charger to up to four batteries, either in or out of a vehicle and forget about it until you are ready to use it, with the confidence that the batteries in all four vehicles are being maintained at optimal performance levels. This makes it perfect for seasonal and recreational vehicles like motorcycles, jet skis, ATV's, snowmobiles and more,. It is also safe for your battery because it utilizes advanced microprocessor technology that automatically switches its output voltage to a storage or float level. This feature eliminates the need to worry about the damaging effects of overcharging, and the resulting need to check on the condition of a charging battery. If or when the battery voltage drops too far under load, this same smart technology resumes output power and the charging cycle begins again. The unit also features spark-proof connectors, short circuit and reverse polarity protection, an easy to understand charging status LED indicator for each charging bank, durable yet lightweight construction and almost no current draw from batteries connected to it. Key Features:
- Four independent charging stations.
- 12 volts/1.25 amps per charging bank.
- Extremely lightweight at less than 3 lbs.
- Operates anywhere in the world. 100-240 VAC, 50/60 Hz.
- Microprocessor controlled constant current charging.
- Spark-proof and reverse polarity/short circuit protected.
- Temperature compensated to ensure optimum charge voltage according to ambient temperature.
- Perfect for all AGM (absorbed glass mat), sealed maintenance free and flooded batteries.
- Designed to meet U.S. and International product safety standards (UL/CE).
- 2-year warranty.

|*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. |
