Gel batteries, also known as acid gel batteries, are a type of VRLA battery that is a branch of UPS sealed acid batteries. The technology used to make the gel battery is similar to that of an AGM battery. However, instead of the glass-based adsorbent used in AGM UPS batteries, gel batteries use gel electrolytes. Solid electrolytes reduce the risk of loss and evaporation of UPS battery electrolytes and prevent corrosion problems.

Compared to regular UPS batteries, gel UPS batteries are much lighter. This technology uses only a small amount of solid electrolyte to preserve the acid. Also, UPS acid gel batteries have a longer lifespan than other types of UPS batteries, which is why the electrolyte in the gel state can hold a charge for a longer period of time. The gel batteries are also more durable and can Tolerate more temperature change than a normal UPS battery.

Cases of gel batteries
Gel batteries are commonly used in a variety of motorcycles, marine equipment, race and off-road vehicles, and wind power solar as well as UPSs. This type of battery is also used in high-tech electric vehicles. Due to the non-maintenance feature of these batteries, consumers do not have to regularly add water to the battery to keep the electrolyte level at a normal level. Acid gel car batteries have less acid than deep cycle batteries, and by changing the state of the electrolyte solution from liquid to gel, it is almost impossible for the electrolyte to leak.
