These dependable batteries are often used in marine vehicles, RVs, golf carts, wheelchairs and scooters, UPS systems and high end motorcycles where durability is required or battery orientation is an issue. If well maintained, they last longer than SLA batteries.They have a low self-discharge rate, meaning they can be stored for longer before they require a charge.They produce minimal gassing, so they can be used in less well ventilated areas.They can be installed in any orientation.If they are frozen, even though they won’t operate, they are not damaged. They can withstand colder temperatures than a typical wet cell battery.

They were designed to withstand the constant vibration of military airplanes and helicopters. They are safe to transport and are exempt from hazardous materials restrictions. Because the acid is held in the fiberglass mats, they won’t spill, even if they are broken. This construction gives them some advantages over traditional, flooded, Sealed Lead Acid batteries. In an AGM battery, the electrolyte is held next to the plates in thin fiberglass mats, instead of freely flooding the plates. Used in military aircraft, heavy duty vehicles and UPS, among other applications, they are lighter and more reliable, and able to withstand more punishing use. – Combination terminals – For easy hook-upĪll batteries are made in the USA, your assurance of quality.As we learned in Types of Lead Acid Batteries, AGM (Absorbed Glass Mat) batteries, designed originally for the military, came into wide use in the 1980’s. – Safety relief valve system – Safer operation and safer charging – Glass mat separators – Spillproof and leakproof properties – Faster charging rates – Faster turnaround times – Resists vibration damage – Provides longer operation over time – Lower electrical resistance – Provides higher discharge rates, quick starts – Spill Proof, valve-regulated design – Eliminates acid leaks and terminal corrosion – Maintenance-free construction – Eliminates the need to add water Absorbed Glass Mat Dual Purpose Batteries For 12-volt AGM batteries, charge to at least 14.4 volts, but no more than 14.6 volts at 68͒° F (20° C).

** Charging: use a good, constant potential, voltage-regulated charger. Power wheelchairs use these types of batteries. Rated non-spillable by International Commercial Airline Association (ICAO), International Airline Transport Association (IATA) and DOT definitions. *Good to Know – Can I travel on an airplane with these batteries? Yes.

AGM batteries are also completely maintenance-free. The completely sealed, valve-regulated AGM battery eliminates gas emissions and acid leakage for longer and safer battery operation. Lower internal resistance also means that the batteries can be recharged faster than conventional batteries,** allowing the user to put them back into operation sooner. Sealed, Valve-Regulated (SVR) Absorbed Glass Mat batteries (AGM) use special absorbed electrolyte technology that is superior to flooded lead-acid batteries.įine, highly porous microfiber glass separators absorb the electrolyte*, increasing efficiency by lowering internal resistance and boosting capacity. AGMs provide very low internal electrical resistance and combined with faster acid migration, allow them to deliver and accept higher amperage rates during discharging and charging cycles. This technology delivers improved performance, reliability and safety over all existing sealed batteries including the Gel. Originally developed in the early 1980s, AGM batteries became the standard for military aircraft because power, weight, safety and dependability were concerns. What is A.G.M.?
