什么is the Difference Between AGM and GEL Batteries

Thekey difference between AGM and GEL batteriesis that AGM batteries allow discharging up to 50%, whereas GEL batteries allow discharging up to 90%, ensuring a long service life.

AGM and GEL batteries are types oflead-acid batterieshaving a lot in common. But there are some differences between AGM and GEL batteries as well. Both these types of batteries use valve regulated lead acid technology, and both these batteries tend to maintain free and non-spillable nature. However, they have differences in their service life and discharging nature.

什么are AGM Batteries?

AGM batteries areAbsorbed Glass Mat batteriesthat are designed uniquely to trap theelectrolytebetween the plates inside the battery. These batteries are also known asSLA batteries, meaning sealed lead-acid batteries orVRLA batteries, meaning valve-regulated lead-acid batteries. We can characterize this type of battery by a limited amount of electrolyte that is absorbed in a plate separator or formed into a gel that proportionates the negative and positive plates so that the recombination of oxygen can be facilitated within the cell.

These batteries only hold a small amount of acid, unlike traditionalwet batteries. This little amount of lead acid is entirely absorbed by the glass mat. It acts as a major safety feature that prevents the acid from leaking from the battery even if the battery gets broken. Therefore, we can name these batteries non-spillable and maintenance-free batteries. They have a wide range of applications, including use in emergency lights, alarm systems, medical equipment, and UPS.

什么are GEL Batteries?

GEL batteries are a type of lead-acid battery that is built with a gel electrolyte. This gel electrolyte is designed to mix with sulfuric acid and fumed silica, which causes a chemical reaction to occur. This chemical reaction causes the gel electrolytes to be immobile. In addition, it is helpful to make the battery free of maintenance and spill-proof. Therefore, we can install the battery in any direction without worrying about acid leaks.

Moreover, GEL batteries have deep cycling capabilities, which makes them an ideal battery option for many applications. These include applications such as solar and wind energy, electric vehicles, wheelchairs, golf carts, cleaning equipment, etc.

AGM batteries are Absorbed Glass Mat batteries that are designed uniquely to trap the electrolyte between the plates inside the batteries, while GEL batteries are a type of lead-acid batteries that are built with a gel electrolyte. The key difference between AGM and GEL batteries is that AGM batteries allow discharging up to 50%, whereas GEL batteries allow discharging up to 90% ensuring a long service life. In AGM batteries, a little amount of lead acid is entirely absorbed by the glass mat, whereas in GEL batteries, electrolyte is designed to mix with the sulfuric acid and fumed silica which causes a chemical reaction to occur where the reaction causes the gel electrolytes to be immobile.
