AGM batteries

AGM is the abbreviation for Absorbent Glass Mat. In these batteries, the electrolyte is absorbed by capillary action in a fiberglass mat placed between the plates.

AGM batteries, it is often written VRLA (Valve Regulated Lead Acid). Which means the battery is waterproof. Gas will escape through safety valves only in the event of overload or element failure.

AGM batteries are better able to deliver high currents for short periods of time than Gel batteries.

Maintenance free.

Low self-discharge

Through the use of lead-calcium grids and high purity materials, VRLA Ultimatron batteries can be stored for a long time without requiring recharging. The self-discharge rate is less than 2% per month at 20ºC. Self-discharge doubles for every 10ºC increase in temperature. In cold conditions, Ultimatron VRLA batteries can therefore be stored for up to a year without recharging.

Exceptional deep discharge recovery

Ultimatron VRLA batteries have exceptional recovery capacity even after deep or prolonged discharge. However, it should be noted that frequent deep or prolonged discharges have a detrimental influence on the life of any lead acid battery, and Ultimatron batteries are no exception.
