What is the difference between AGM batteries and conventional batteries?

The AGM battery refers to a battery made of ultra-fine glass wool material, which has many differences compared with ordinary batteries. The AGM battery is sealed and has a venting valve on the battery cover. During normal use, no hydration is required. Conventional batteries are unsealed. The electrolyte can be seen by opening the liquid injection cover and it is necessary to replenish water frequently during use.


Compared with batteries of the same specification, the price is higher, but has the following advantages:

1. The cycle charging capacity is 3 times higher than that of lead-calcium batteries, and has a longer service life.

2. Higher capacitance stability throughout the life cycle.

3. Low temperature start is more reliable.

4. Reduce the risk of accidents and reduce the risk of environmental pollution (since the acid is 100% sealed).

Compared with other batteries, AGM batteries are safer and suitable for use in some high-power applications in series and parallel.
