The Dynacell Difference

Sealed Valve Regulated (SVR)
Gas Recombinant Battery

Dynacell uses the "recombination" technique to replace oxygen and hydrogen normally lost in a wet cell (particularly in deep cycle applications).

The Dynacell battery is non-spillable, and therefore can be operated in virtually any position. However, installation upside-down is not recommended.


How does it work?

A "recombinant" battery means that the oxygen that is normally produced on the positive plate in all lead-acid batteries recombines with the hydrogen given off by the negative plate. The "recombination" of hydrogen and oxygen produces water, which replaces the moisture in the battery. Therefore, the battery is maintenance free, as it never needs watering.

The oxygen is trapped in the cell by special pressurized sealing vents. It travels to the negative plate through tiny fissures or cracks in the gelled electrolyte.

The sealing vent is critical to the performance of the gel cell. The cell must maintain a positive internal pressure. Otherwise the recombination of the gasses will not take place, and the cell will dry out and not perform.

In addition, the valve must safely release any excess pressure that may be produced during overcharging. Otherwise the cell would be irreparable damaged.


Exclusive Formula

The electrolyte is another critical element in this type of battery. Our gelled electrolyte contains sulfuric acid, fumed silica, pure demineralized and deionized water, and a phosphuric acid additive. The phosphuric acid is a key reason that our batteries deliver 4 to 10 times longer cycle life than leading gel competitors and 3 times longer cycle life than traditional wet cells.


- Tank Formed Plates

DYNACELL distributes batteries from the only manufacturer that uses tank formation to activate the battery plates. This process guarantees a fully formed and voltage matched plate. The extra handling of the plates provides an additional inspection step in the process to verify plate quality.


- Ultrapremium, Glass Mat, Dual Insulation Separators

An ultrapremium grade separator is used in our gel cells. We believe that this expense (which is 5 to 6 times higher then other types) is worth the benefits of extended life and performance:

  • The fiberglass mats imbed themselves into the surface of the plates, acting like reinforced rods in concrete. This extra reinforcement locks the active material onto the plate for longer life and extended performance.
  • The ultra-clean separators have no oil contamination or other impurities. Therefore, resistance is low and battery performance is high.
  • Excellent porosity allows maximum electron flow, which means more power-per-pound.
  • Superior resistance to oxidation dramatically reduces separator failure, which extends life.


Charging Information

It is critical that a charge be used that limits the voltage to more more then 14.1 volts and no less then 13.8 volts at 68oF. Batteries used in float service should be charged at 13.8 volts. For deep cycle service, a maximum voltage of 14.1 should be used. The charger must be temperature corrected to prevent under or overcharging due to ambient temperature changes.
