What is a Gel battery?

A gel battery is a lead-acid electric storage battery that:

    * Is sealed using special pressure valves and should never is opened.
    * Typically uses Calcium/Calcium metal alloys.
    * With proper maintenance, is completely maintenance-free.
    * Uses gelled electrolyte.
    * Uses a recombination reaction to prevent the escape of hydrogen and oxygen gases normally lost in a flooded lead-acid battery (particularly in deep cycle applications).
    * Is non-spill able, and therefore can be operated in virtually any position with little capacity lost. However, upside-down installation is not recommended.
