Battery Tender 021-0156 Battery Tender Plus 12V Battery Charger True Gel Cell Model Review
Battery Tender 021-0156 Battery Tender Plus 12V Battery Charger True Gel Cell Model Feature
- Temperature-compensated to ensure optimum charge voltage according to ambient temperature
- Unique Gel Cell battery adjusted software allows for a slightly lower charge voltage and higher store voltage to protect sensitive true Gel Cell batteries
- Charges 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) allows for optimal constant battery levels without overcharging
- Automatically switches to float/maintenance voltage mode after fully charging the battery
The Battery Tender Plus 12-volt/1.25-amp Battery Charger True Gel Cell model is the best way to deal with the challenge of keeping 12-volt vehicle batteries optimally powered when not in use, especially for users who own true Gel Cell batteries. It is not only able to charge any 12-volt lead-acid battery, its specially adjusted internal software allows for a slightly lowered voltage level that protects sensitive Gel Cell batteries from the dangers of overcharging. It is also designed to be easy to use in difficult spaces, to utilize a 4-step charging program and safely function in a fully automatic mode. Taken together this makes the special Gel Cell version of the Battery Tender Plus 12-volt/1.25-amp Battery Charger an excellent means of ensuring that all your batteries are fully charged and ready to go when you are.
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.
