AGM Batteries

Absorbed Glass Mat (AGM) batteries are the latest step in the evolution of lead-acid batteries. Instead of using a gel, an AGM uses a fiberglass like separator to hold the electrolyte in place. The physical bond between the separator fibers, the lead plates, and the container make AGMs spill-proof and the most vibration and impact resistant lead-acid batteries available today. Even better, AGMs use almost the same voltage set-points as flooded cells and thus can be used as drop-in replacements for flooded cell batteries.

The higher charge efficiency of AGM batteries can contribute to significant savings when it comes to the use of renewable energy sources (wind generators, solar panels, etc.) as your charging system can be 15% smaller (or just charge faster). The construction of AGMs allows them to be used in environments where other batteries would literally fall to pieces. This is another reason why AGMs see broad use in the aviation, RV, marine and golf car industry.

Here you can find a big selection of low priced AGM solar batteries from all the top brands including MK Battery, Deka Solar, Hawker, Trojan, Rolls and Concorde.

What is the difference between AGM and Gel batteries?

Both AGM and Gel batteries utilize oxygen recombination and pressure relief valves to minimize water loss and allow maintenance-free operation. That is where the similarities end. AGM batteries have the advantage of being mountable in any orientation without capacity loss, have lower internal impedance to support high load currents, and have better capacity at low temperatures. Gel batteries must be mounted upright to prevent air pockets from forming that will burn out the plates. They have inferior performance at high discharge rates and low temperatures.
