Description of 12v2.3ah battery
Application
Maintenance free storage battery 12V2.3ah is used for fire alarm system, automatic door, automatic packing lock and so on.
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.
