What’s a Gel Cell?
The Gel Cell battery is similar to the AGM (Absorbed Glass Mat) battery in that its contents are sealed, but different because technically the AGM battery is still considered to be a wet cell. The guts of a Gel Cell contain a silica additive that causes it to set up or stiffen, first like Jell-O, then after subsequent discharge/charge cycles more like peanut brittle. Micro-cracks form in this gelled electrolyte that provide paths for the oxygen recombination reactions between the positive and negative plates. The recharge voltages on this type of cell are lower than the other styles of lead acid battery making it probably the most sensitive cell in terms of adverse reactions to over-voltage charging, and thus needing special care.

Safe, 4-step Battery Charging for True Gel-Cell Batteries
Powered by BTP microprocessor technology and utilizing a 4-step charging program (initialization, bulk charge, absorption mode and float mode), the Battery Tender Plus 12-volt/1.25-amp Battery Charger 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 which eliminates the need to worry about the damaging effects of overcharging, and the resulting need to check on the condition of the battery. This is taken even further with the Gel Cell model, which possess a higher store rate and lower charge rate, minimizing the chance of mistaken overcharging. The unit also features sparkproof connectors, short circuit and reverse polarity protection, an easy to understand charging status LED indicator, a quick connect harness for use in hard to reach areas and almost no current draw from batteries connected to.

Key Features:

• Unique Gel Cell battery adjusted software.
• 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.
• Temperature compensated to ensure optimum charge voltage according to ambient temperature.
• Solid state two color LED indicates stage of charger.
• Spark proof and reverse polarity protected.
• Includes quick connect harness for use in hard to reach areas.
• 10 year warranty.
