Sealed Gel Battery tends to consume more power faster than Sealed AGM Battery, especially at lower temperatures. This is because of the gel thixotropic composition of the battery. The sealed AGM Battery works in extreme weather, making it suitable for power-hungry winter utilities, such as snowmobiles.
In terms of depth of discharge (DoD), Sealed Gel Battery utilizes acid better than Sealed AGM Battery. Acid protects the plate of the gel battery and enhances its deep discharge application. However, the Sealed Gel Battery must be charged correctly, otherwise, it will fail prematurely. The scars on the inside of the jelly material will produce small packets that will corrode the plate.
Sealed AGM Battery is cheaper than Sealed Gel Battery, but they have a longer service life and provide larger current pulses when needed. These batteries work best in high-power applications, such as sports vehicles.
In terms of durability, long life, and charging, the sales of Sealed AGM Battery surpassed the gel type. They are also cheaper and can work in different weather conditions.
Compared with the Sealed AGM Battery, Sealed Gel Battery has a lower leakage percentage due to its gel composition.
