The Battery Tender 12-volt/2-amp 10-Bank Battery Management System is designed for commercial use in keeping up to 10 12-volt batteries simultaneously charged and maintained, 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 everything from some automotive/farm equipment to motorcycles, ATV’s, and personal watercraft, this lightweight, microprocessor controlled unit provides safe, constant, 4-step charging current for every vehicle stored in your shop. Simultaneous charging of up to 10 separate batteries. View larger. The 4-step charge cycle detailed. View larger. Smart, Commercial Grade 4-step Battery Charging The first fully automatic, constant-current battery charger designed to charge and/or maintain up to 10 12-volt batteries simultaneously at 2 amps, the Battery Tender 12-volt/2-amp 10-Bank Battery Management System utilizes a 4-step charging program (initialization, bulk charge, absorption mode and float mode), that allows users to connect the charger to up to 10 batteries, either in or out of a vehicle, with the confidence that all are being maintained at optimal performance levels. This makes it extremely useful for battery rotation, where a battery is removed from service during repair or in preparing batteries for sale. It is also safe for your batteries, with the built-in ability to automatically switch its output voltage to a 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 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 sparkproof connectors, reverse polarity protection, a 72-hour safety timer that ensures batteries attain float mode status during charging, an easy to understand charging status LED indicator for each charging bank, durable construction and almost no current draw from batteries connected to it. Key Features: Simultaneously charges and/or maintains up to 10 12-volt batteries. 12 volts/2 amps per charging bank. Maintains batteries at full charge without overcharging via its 4-step charging system. Spark-free design via microchip circuitry that will not activate output voltage until clips are correctly connected to battery. Reverse polarity protection and a built-in 72-hour safety timer that ensures batteries attain float mode status. Six foot lead with alligator clamps included. 3-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. Three-year Limited Warranty Deltran provides a limited three-year warranty on its Battery Tender 12-volt/2-amp 10-Bank Battery Management System to the original purchaser based on defective material or workmanship. Warranty is void in cases of product misuse, disassembly or modification. Other details regarding warranty limitations and procedures are contained in the Deltran Battery Tender Charger's general limited warranty information sheet enclosed with this product.

This review is from: Battery Tender 021-0134 10-Bank 12V Battery Management System (Misc.)

Have only owned the product for a month, but am completely satisfied.
Does everything I would have expected. I collect motorcycles and never remove the batteries. I'm too lazy to move a charger from bike to bike. I've plugged in most of the bikes plus a car that I seldom use in the winter and leave them on. No worries.
Only negative I've found is the leads from the charger to the battery are only 6 feet long. If you require more, you need to purchase a 25 foot extension. 31 feet is much more than I need. Wish I could purchase leads of 10 to 15 feet long.

This review is from: Battery Tender 021-0134 10-Bank 12V Battery Management System (Misc.)

I live on a small farm and have many pieces of equipment that have batteries. I was able to remove the batteries and place them on a work bench and charge 10 of them at one time. Plus this unit will keep them at peak level until spring arrives.

Beware buying this charger. They break down easily. Customer service is no help at all. Repair is expensive. I bought 2 and neither worked properly when I received them. If they worked correctly, it would be a wonderful product. I have other chargers from Deltran that work great, this one however...
