Another Marineland technology in Dubai and Sharjah, UAE is AGM absorbent glass mat technology. The technology consists of an acidic lead-acid battery. In 12-volt AGM batteries, lead plates are placed between fiberglass-saturated electrolyte mattresses. This increases the efficiency of discharging and recharging. These batteries can be a replacement for traditional lead-acid batteries. By definition, AGM batteries became very popular in the 1980s. They were used to power motorcycles, the military, airplanes and submarines, but can now be found in everyday cars and trucks. AGM batteries are a maintenance-free replacement for traditional lead-acid batteries.
