The difference between AGM & GEL battery

27 Aug 2021

It's a rough battle to distinguish which one is better between AGM and GEL. AGM batteries and Gel batteries have a lot in common. Both categorized under Sealed Lead-Acid Batteries. Both batteries possess similar traits such as having deep-cycle capabilities, spill-proof design and both can be used in different orientations. The two battery types are also known for their low self-discharge, maintenance free and vibration-resistant characteristics. However, AGM and Gel are two distinctly different types of batteries.

AGM vs GEL

Definition:
AGM (absorbed glass mat) is a special design with absorbed glass mat technology refers to a fine fiberglass mat that is capable of absorbing sulfuric acid and wick the electrolyte between the battery plates. AGM batteries contain only enough liquid to keep the mat wet with the electrolyte and if the battery is broken no free liquid is available to leak out.
A Gel cell battery is a battery that uses a sulfuric acid that has been mixed with fumed silica to create a gel-like substance that is immobile. Because of the GEL cell, the battery does not have to be kept upright and the electrons can flow between the plates without the threat of spilling.

How to choose which battery is suitable:

EverExceed manufactures both AGM and GEL batteries which adopts latest technology. So when trying to decide which battery to purchase consider a few things.
1. What application are you using the battery for?
2. Will the battery have to function in below freezing temperatures or high temperature?
3. How will you recharge the battery?
4. Do you need a slow discharge rate or will you require bursts of power?

Once you have the answers to these questions EverExceed will help you to determine the best battery for you. Understanding the battery you are purchasing will go a long way in preventing damage to your equipment and preserving the life of the battery
