What is an AGM battery?
An AGM battery is a lead-acid electric storage battery that:
- Uses various plate thicknesses relative to application and user cost requirements.
- Is sealed using special pressure valves and should never be opened.
- Typically uses Calcium/Calcium metal alloys.
- With proper maintenance, is completely maintenance-free.
- Has its entire electrolyte absorbed in separators consisting of a sponge-like mass of matted glass fibers.
- (***) Electrolyte volume and S.G to active material ratios may very according to application and market conditions.
- Uses a recombination reaction to prevent the escape of hydrogen and oxygen gases normally lost in a flooded lead acid battery (particularly in any cycling application).
- Is non spill-able.
*** Available amounts of usable amp hours CAN BE ADJUSTEDBY AS MUCH AS 30% by adjusting the acid and active material densities.Buyers should be aware that increasing acid specific gravities and acid to active material ratios will severely reduce the batteries life cycle expectancyas well as increase the available usable power per discharge cycle. Otherwise a75 amp hour battery can be made to deliver 100 amp hours by increasing the acidto active material ratio and the specific gravity of the acid. Both of these adjustments will severely reduce the life of the battery. Therefore, if you are quoted an unbelievable price on a 100AH battery given the current market pricing, you may now know why! Adjusting acid specific gravities and acid toactive material ratios may make sense to a particular user who wishes to increase cold weather performance but the user should again beware that life will be negatively affected.
