Gel Cell batteries are Deep Cycle Lead Acid batteries that use an electrolyte containing a gelling agent.
Gel cells will not leak if inverted or pierced and will continue to operate even under water.
Gel cells require no maintenance once the charging system has been set up.
The faster, more efficient bulk charging of Gel-Cells will lead to reduced wear and tear on your charge source (engine, generator, etc.).
Gel-Cells dispense charge at a higher rate than flooded cells.
Deep-cycle gel batteries are highly recommended by the National Renewable Energy Labs.
Deep-Cycle Gel Cell batteries are lead-acid batteries, but differ in construction and chemistry than Wet Cells. They offer unique features such as: No maintenance, low self- discharge rate, and low internal resistance.
Gel Cells use a thickening agent like fumed silica to immobilize the electrolyte. If the battery container cracks, the cell will still continue to function.
The thickening agent prevents stratification by preventing the movement of electrolyte. They will not leak and continue to operate even under water.
Gel cells cannot be re-filled with electrolyte, and controlling the rate of charge is very important.Battery compartments need to be ventilated.
Gel cells use slightly lower charging voltages than flooded cells so the set-points for charging equipment have to be adjusted.
Virtually no gassing under normal operating conditions: Gel cells are hermetically sealed and operate under pressure to recombine oxygen and hydrogen during the charge process into water.
Gel cell advantages include: No equalization charges, no electrolyte to replenish, no specific gravity checks.
The faster, more efficient bulk charging leads to reduced wear and tear on the charge source.
Gel-cells can dispense charge at a higher rate than flooded cells due to their lower Peukerts exponent.
Sealed Gel Cells may be shipped anywhere by air as approved by DOT (Department of Transportation), ICAO (International Commercial Airline Organization), and IATA (International Airline Transport Association).
