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 be opened. • is completely maintenance-free.* • uses thixotropic gelled electrolyte. • uses a recombination reaction to prevent the escape of hydrogen and oxygen gases normally lost in a flooded
