To make an informed decision on the correct battery for your needs, it is essential to understand the different types of sealed, valve-regulated battery options that are available.

In this blog post, we will delve into the similarities and differences between GEL and AGM batteries, providing you with the necessary knowledge to choose the most suitable option.

Similarities 

It’s a common misconception that GEL and AGM batteries are fully interchangeable due to their many similarities. There are some critical differences between the two, but first, let’s take a closer look at some of the similarities:

Both GEL and AGM

  • Sealed and Maintenance Free 
  • Non-Spillable 
  • Deep Cycle Design
  • Longer Shelf Life  
  • One-Way Pressure Valves 
  • Air Travel Approved (MK) 

GEL Batteries

Genuine GEL batteries utilize gelled electrolytes to reduce the risk of spillage. GEL batteries are generally lighter than others, and the gelled electrolyte solution gives them a longer battery life. The cycle life of a Genuine GEL battery can be at least double that of an AGM product, if properly maintained. Genuine GEL batteries are commonly used in complex rehab power wheelchairs, scooters, and marine equipment. 

AGM Batteries 

Unlike GEL batteries, AGM batteries use a starved electrolyte absorbent glass mat material, which absorbs the electrolyte mixture via the fiberglass mat separator. AGM batteries can perform in lower temperatures, may have faster charging times, and have lower internal resistance. You will most commonly find AGM batteries being utilized in cars, motorcycles, military vehicles, lighter duty scooters, and more! 

Differences

The main difference in construction between these two battery options is that Genuine GEL batteries incorporate a suspended gelled electrolyte while AGM batteries utilize a glass mat containing thin glass fibers to absorb the liquid electrolyte. Both batteries can be excellent options depending on their intended use; choosing one depends on the specific application and preferred battery life.
