What is the Difference Between AGM and GEL Batteries?
🆚 Go to Comparative Table 🆚AGM (Absorbed Glass Mat) and GEL batteries are both sealed lead-acid batteries with similar attributes, but they have some key differences:
- Electrolyte: AGM batteries use an absorbed glass mat material to hold their electrolyte, while GEL batteries use a gel paste in which the electrolyte is suspended.
- Temperature sensitivity: GEL batteries are less sensitive to temperature and perform better in extreme temperatures than AGM batteries.
- Leakage: GEL batteries are less likely to leak than AGM batteries due to the better sealing of the electrolyte.
- Weight: GEL batteries are typically heavier than AGM batteries, making them more challenging to transport and install.
- Performance: AGM batteries generally offer better performance, faster charging, and better performance in colder operating conditions.
- Cost: AGM batteries are usually less expensive than GEL batteries.
- Charging: GEL batteries have very narrow charging profiles and can be damaged easily by charging them with settings not suitable for GEL batteries.
When choosing between AGM and GEL batteries, it's essential to consider the specific needs of your application, such as temperature, leakage, weight, cost, and performance. In most cases, AGM batteries are a better choice due to their lower cost, better performance, and wider operating range. However, GEL batteries may be the better option for applications with a long lifespan or in extreme temperature conditions.
Comparative Table: AGM vs GEL Batteries
AGM and GEL batteries are both types of valve-regulated lead-acid (VRLA) batteries, but they have some differences in terms of electrolyte, discharge, and temperature sensitivity. Here is a table comparing the differences between AGM and GEL batteries:
Feature | AGM Batteries | GEL Batteries |
---|---|---|
Electrolyte | Absorbed in glass mat like separators | Jelly-like electrolyte |
Discharge | Allow discharging up to 50% | Allow discharging up to 90%, ensuring a long service life |
Temperature Sensitivity | Efficient in cold temperatures | Work in warmer temperatures |
Internal Construction | Fiberglass separator, making them impact resistant and spill-proof | Slightly stronger than flooded batteries, but not as strong as AGMs |
Both AGM and GEL batteries are spill-proof, low-maintenance, and have flat tops for easy mounting. However, their differences make them suitable for different application scenarios. AGM batteries are more efficient in cold temperatures and are impact resistant, making them ideal for high bursts of power and maintenance-free operation. On the other hand, GEL batteries work well in warmer temperatures and can be discharged more deeply, ensuring a longer service life.
