What’s the different between sub gel batteries and full gel batteries

This article describes the difference between subgel batteries and all-gel batteries. In a nutshell, there are differences between the two types of batteries in terms of structure, working principle and scope of application. By understanding these differences, you can better choose the battery that suits your application scenario.

Both sub-gel batteries (AGM,) and full-gel batteries (GEL) are sealed, maintenance-free lead-acid batteries. They are suitable for a variety of applications, such as common generator backup power and electric vehicles. However, they have different operating principles and performance.

Difference in working principle

1. AGM battery

AGM batteries absorb electrolyte to reduce gassing and leakage in the battery by placing a layer of absorbent glass fiber (AGM) between the battery plates. It is tightly constructed, requires no water addition, and is suitable for high current applications.

2. Full Gel Battery

The electrolyte in GEL batteries is cured into a gel, forming a gel-like substance. By this way, the battery has higher durability and better high and low temperature performance, as well as being more suitable for high cycle applications.GEL batteries are tightly structured and require no maintenance.

1. AGM battery

AGM battery is a high power battery with good starting performance and transient current performance. In cold weather, AGM batteries are able to provide more powerful starting current and it has better leakage protection.The life span of AGM batteries is relatively short, about 3-5 years.

2. GEL battery

GEL batteries, on the other hand, are high-cycle batteries that can withstand deeper discharge depths and are suitable for long standby and cycling applications. Compared with AGM, GEL batteries have lower internal cell resistance and better low temperature performance.

Difference in scope of application:

1. AGM battery

AGM battery is a high power battery with good starting performance and transient current performance. In cold weather, AGM batteries are able to provide more powerful starting current and it has better leakage protection.The life span of AGM batteries is relatively short, about 3-5 years.

2. GEL battery

GEL batteries, on the other hand, are high-cycle batteries that can withstand deeper discharge depths and are suitable for long standby and cycling applications. Compared with AGM, GEL batteries have lower internal cell resistance and better low temperature performance.

Difference in scope of application:

1. AGM battery

AGM batteries are suitable for high transient loads and high power load applications, such as vehicle starting, electrical equipment applications, etc.

2. full gel batteries

GEL batteries are suitable for low temperature, high cycle and long time standby applications, such as solar energy applications, UPS etc.

Frequently Asked Questions

1. Which one of the two batteries is better?

This question needs to be decided based on the specific application. For high power load applications, AGM batteries are recommended; for long standby and cycling applications, Gel batteries may be better.

2. What is the price difference between the two types of batteries?

Generally speaking, GEL batteries are slightly more expensive than AGM batteries. This is due to the fact that GEL batteries have better cycle life and better low temperature performance, among other features.
