AGM Battery Versus Gel Battery: Which Is Better?

Both categorized under Sealed Lead-Acid Batteries, AGM (Absorbent Glass Matt) Battery and Gel Battery are often mistaken to be the same. Both batteries possess similar traits such as having deep-cycle capabilities, non-spillable design and both can be used in different orientations. The two battery types are also known for their low self-discharge, low-maintenance and vibration-resistant characteristics. However, AGM and Gel are two distinctly different types of batteries.

Comparing the Two Battery Types

Gel batteries tend to lose power faster than AGM batteries, especially at lower temperatures. This is because of the gelled Thixotropic composition of the battery. AGM batteries work in extreme weather, making them suitable for power-hungry winter utilities such as snow-mobiles.

When it comes to Depth of Discharge (DoD), Gel batteries make use of acid better than AGM batteries. Acid protects the Gel batteries' plates, enhancing their deep discharge applications. However, a Gel battery must be recharged correctly, or else it will suffer premature failure. A scar inside its jelly material can create packets that will corrode the plates.

AGM batteries are comparably cheaper than Gel batteries, but they present a longer life span and offer bigger bursts of amps when needed. These batteries work best in high-power usage, such as sports vehicles.


AGM Batteries outsell Gel types when it comes to durability, long life and charging. They are also less expensive and work in different weather conditions.

Gel batteries, due to their gelled composition, present less leaking percentage when compared to AGM batteries.
