|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.

Like it. I store my car a lot and only occasionally drive it on the weekends. My battery used to become discharged, but using this charger keeps it fully charged and I don't... Read morePublished 11 days ago by JD
The thing is advertised as a charger for a "gel cell" type battery. However the info that comes with the unit states "use only on a lead acid type" battery. Read morePublished 12 days ago by Steve C.
Used many of these over the years. Never failed me, just one more for another toy to save buying batteries every year.Published 13 days ago by T. Smith
