MK Battery is one of the largest sealed lead acid battery distributors in North America due to our total commitment to the following principles:

Products

Whether your application requires extended cycle life, long duration at low rates of discharge, minimal recharge time, maximum high-rate performance or even a specialty flooded product, MK Battery manufactures and distributes only the highest quality batteries available anywhere. Not only do we continually test our own batteries; we carefully evaluate other manufacturers products as well. Moreover, we assess their overall capabilities as potential suppliers to assure that we are delivering to you the most effective technology for your unique requirements. "A battery is just a battery" does not apply here.

Service

"Ship fresh inventory within 24 hours from the nearest point to our customer while providing worry-free spent battery disposal." This is the MK Battery service axiom. Consequently, we ship our products from more than 50 locations in North America, have MK Regional Offices in ten states and ship MK products through MK distributors worldwide. Concerning recycling, MK Battery assures our customers that all of their spent batteries are delivered to E.P.A. - permitted smelters exclusively. That is critical for you because hazardous waste disposal laws place heavy penalties on offenders. In summary, MK Battery listens to our customers and delivers what you want, when you need it.

Commitment

MK Battery is growing rapidly because we specialize in sealed battery markets that are also expanding. Moreover, because of our narrow focus on sealed batteries and these niche markets, we can offer you expertise in these areas that very few of our competitors will match. Finally, you can expect our total commitment to keep you safely at the forefront of high-quality battery technology with the most responsive service.

Deka/MK Battery 8G22NF-DEKA Sealed Gel Battery, 12 volt 51 AH

Terminal Type: T881
Battery Group: 24

Note: Deka Solar Batteries and MK Sealed Valve Regulated Gelled Electrolyte Lead-Acid Batteries are the exact same battery, just different labels. (Stud terminals standard, other terminals available)

Benefits

Completely maintenance free.
Sealed construction eliminates periodic watering, corrosive acid fumes and spills.
Electrolyte will not stratify, no equalization charging required.
Allows faster recharge.
Increases durability and deep cycle ability for heavy demand applications.
Less than 2% per month stand loss means little deterioration during transport and storage.
Tank formation ensures voltage matching between cells.
Batteries under 70 lbs can be easily shipped by UPS, and don't require special freight truck shipping like with flooded lead acid batteries.

Applications

Solar and Wind energy system
Water Pumping
Residential
Communications
Cathodic Protection
Remote Monitoring
Refrigeration
Lighting Aids to Navigation
Wheelchairs
RVs
Golf Carts

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 battery recombines with the hydrogen given off by the negative plate. The "recombination" of hydrogen and oxygen produces water (H2O), 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 irreparably damaged.

It's important to note that gel cell must never be opened. If opened, the cell loses its pressure, and the outside air will "poison" the plates and cause an imbalance that destroys the recombination chemistry.

How do gel cells recharge? Are there any special precautions?
While our gel cell will accept a charge extremely well due to its low internal resistance, any battery will be damaged by continual under- or overcharging. Capacity is reduced and life is shortened.

Overcharging is especially harmful to gel cells because of their sealed design. Overcharging dries out the electrolyte by driving the oxygen and hydrogen out of the battery through the safety valves. Performance and life are reduced.

If a battery is continually undercharged, a power-robbing layer of sulfate will build up on the positive plate, which acts a s a barrier to electron flow. Premature plate shedding can also occur. Performance is reduced and life is shortened.

Therefore, it is critical that a charge be used that limits voltage to no more than 14.1 volts and no less than 13.8 volts at 68°F. Batteries used in float service should be charged at 13.8 volts. For deep cycle service, a maximum voltage of 14.1 volts should be used. Most of the charge controllers that we offer are compatible with gel cell type of batteries.

The charger must be temperature corrected prevent under- or overcharging due to ambient temperature changes. Most charge controllers that Affordable Solar also offer an optional temperature sensor which is placed right on one of the batteries in your battery array. Here are the ones we offer for Trace, Outback, Morningstar and SolarBoost charge controllers:

Can gel cells be installed in sealed battery boxes?
NO! Never install any type of battery in a completely sealed container. Although the normal gasses (oxygen and hydrogen) produced in a gel cell battery will be recombined as described above, and not escape, oxygen and hydrogen will escape from the battery in overcharge condition (as is typical of any type of battery).

For safety's sake, these potentially explosive gasses must be allowed to vent to the atmosphere and must never be trapped in a hermetically sealed battery box or tightly enclosed space!
