How does a Gel Cell Work?
A Gel cell is a “recombinant” battery. This means that
the oxygen that is normally produced on the positive
plate in all lead-acid batteries recombines with the hydro-
gen given off by the negative plate. The “recombination”
of the hydrogen and oxygen produces water (H
2
0), which
replaces the moisture in the battery. Therefore, the
battery is maintenance-free, as it never needs water.

DEEP CYCLE GELL BATTERIES
DOES THE DEPTH OF THE DISCHARGE AFFECT CYCLE LIFE?
YES! The greater the load on the batteries, the sooner they will have to be replaced.
*Typical Gel Cell Cycling Ability
vs. Depth of Discharge
Capacity Withdrawn Typical Life Cycles
100% ........................................................ 300
*75% ........................................................ 450
50% ......................................................... 650
*75% is the average capacity withdrawn for an active user.
*NOTE: Consumers may experience longer or shorter battery life, depending on charging
habits, temperature, and accessories in the system.
