Why AGM batteries are the future
In March 2023, the energy storage system for factories was inaugurated in Huzhou, China.
This system is one of the largest in the world.
The storage system is made up of AGM batteries only.

But let’s take a step back.
What is an AGM battery?
AGM (absorbent glass mat) batteries are a class of lead-acid batteries in which the electrolyte is absorbed into a matrix of thin glass fibres.
The advantages of AGM batteries are numerous.
1. Compact
They are compact, very resistant to mechanical stress (so resistant that they can be used for military purposes) and can be mounted in any position.
They can be used at high altitudes or at sea, and can cope better with high temperatures.
If the container breaks, the acid leakage is limited.
Thanks to the division of the plates by glass fibers, there is no danger of short circuit from cell to cell.
2. High Cranckin Power
They are suitable for starting motors thanks to their very high inrush currents, they have a low self-discharge and a high amperometric yield during charging.
They also have a lower internal resistance than regular lead-acid batteries and maintain a more constant voltage, and charge faster;
Spiral plate batteries have an even shorter charging time.
3. No maintenance
They do not require maintenance.
