Advantage

1. The battery is full of power when it’s out of factory, no need to use liquid charge;

2. no memory, no need to discharge battery use, suitable for circuit design;

3. by high partition, adsorption and strong;

4. there is no flowing liquid (poor liquid), does not leak acid and free Upside down,

5. comply with environmental requirements, ease of use,

6. the use of lead-calcium alloys, battery self-discharge is very low,

7. easy storage, less maintenance;

8. using ABS plastic shell and valve technology for safe use.

Application

Maintenance free storage battery 12v4.5ah is used for building interphone, fire alarm system and so on.
