MK Battery specializes in VRLA sealed lead acid batteries; with 30 years of design experience and using the latest manufacturing technology, today their batteries are one of the best choices for solar and renewable energy systems. Sealed Gel and AGM batteries are the preferred choice for energy systems in remote locations with difficult access where power reliability is a priority. MK Battery is continuously rotating its inventory, ensuring that all the batteries shipped are fresh. The proper disposal of the returned batteries are facilitated through their multiple EPA permitted distribution centers across the US.
MK DEKA gel batteries are completely maintenance free. Sealed gel batteries do not require periodic watering and they can be installed without active ventilation since they do not produce corrosive acid fumes. The sealed construction prevents spills commonly seen around flooded battery banks, this also facilitates transportation without special containers.
The electrolyte in gel batteries is not in liquid form, eliminating the need for equalization and allowing for a faster recharge. DEKA gel batteries have extreme durability and respond better than flooded batteries in applications with heavy power demands. They have less than 2% stand loss per month allowing for longer periods of time in storage without deterioration.
MK gel batteries are constructed using Individual plate formation (IPF) ensuring voltage matching between the cells; the GEL Monobloc batteries have been tested to IEC-61427 standards.

DEKA Gel Batteries Fundamentals
In a gel battery the oxygen produced by the positive plates recombines with the hydrogen released by the negative plate. This produces the water and moisture required for the next cycle, therefore, never needing additional water. The gel cell maintains a positive pressure generated by the sealing vents; without the pressure difference, it would be impossible for the oxygen to travel through the gel towards the negative plates and recombine with the hydrogen. Without the sealing vents the gel cell would be dry.
The valves also release any excess pressure created when the battery is over charged, preventing permanent damage. The cell should never be opened, any alteration will cause the cell to lose its pressure and ruin the balance required for the right chemistry.
One main advantage of gel batteries is that the cells are sealed and they do not spill corrosive electrolyte when they are tipped or the container is damaged. For that reason, flooded batteries are subject to more transportation regulations than gel batteries. Due to the structure of the gel cells, when they are idle, gel batteries present lower loses than wet batteries. They also have more tolerance to deep and extended cycles that could potentially damage the battery.
Like any other battery, repetitive overcharging or over-discharging cycling shortens the life of the battery; in some instances, it will cause irreparable damage. Overcharging is specially harmful to gel batteries, it drives the oxygen and hydrogen out of the cell, drying the gelled electrolyte. 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.
If a gel battery is continuously over-discharged, a layer of sulfate will cover the positive plate, preventing the flow of electrons and the proper recharging. It is very important to set the charge controller using the proper charging parameters. Please look at the attached technical bulletin.
