The greatest characteristic of maintenance free storage battery, just as its name implies is "free maintenance.And the consumption of lead-acid battery electrolyte than it is very small, in the service life of the basic don't need to add distilled water.It also has a shock resistant, high temperature resistant, small volume, the characteristics of uniformity.Relative, of course, it also is more expensive than lead-acid batteries.As for service life, maintenance free storage battery normally suggest replacement cycle for 3 years, and was equal to that of lead-acid batteries.
The difference between the conventional battery and AGM battery:
AGM battery is sealed, the battery cover on the exhaust valve, normal use process, do not need filling water.Conventional batteries are sealed, open the filler cap can see electrolyte, often used to filling water.
Compared with the same specification of battery, the price is higher, but has the following advantages:
1. The loop 3 times higher than calcium lead storage battery charging ability, has a longer service life.
2. In the whole service life cycle has higher capacitance stability.
3. Starting at low temperature is more reliable.
4. Reduce the risk of accidents, reduce environmental pollution risk (due to acid 100% seal).
