Deka Solar Sealed Gel & AGM Battery Review
Gel electrolyte and Absorbed Glass Mat batteries are valve regulated lead-acid.
In a gel battery, the electrolyte does not flow like a normal liquid. The electrolyte has the consistency and appearance of petroleum jelly.
In an AGM battery, highly porous microfiber separators completely absorb and trap the electrolyte. Oxygen formed from the positive plates during charging passes horizontally through the separator pores to the negative plates, where it reacts with hydrogen and changes back to water to replenish the electrolyte.
After many reviews, we have found both Gel and AGM perform well in cold and hot climates. In cold climates AGM capacity loss is minimal and will have a slightly higher voltage at lower temperatures. In hot weather climates, gel batteries tend to outlast AGM batteries due to the nature of the Deka gel electrolyte formula. Both are considered "non-spillable". The "acid-starved" condition of Gel and AGM batteries protects the plates during heavy deep-discharges, giving more protection to the plate. Because of this inherent protection, AGM and Gel batteries are better suited for super-deep discharge applications than traditional lead-acid batteries. Deka Solar Batteries fit these conditions.
