Product Details of 12V 12Ah Lead Acid Battery

1. Free of Maintenance: It’s no request to re-fill electrolyte during service life with the introduction of advanced sealing valve regulated technologies and using AGM separator.

2. No Memory Effect: Some batteries, like Ni-Cd batteries have the characteristics of lasting short time discharge after running for a while or after discharging. This is called Memory Effect. It would not features so for lead acid batteries.

3. Lower Self-Discharge Rate: GMP series are made of special lead-calcium alloy grid that promises the minimum self-discharging and secures long time storage.

4. Long Service Life: Grid is from well fine special lead-calcium alloy and is protected from erosion which leads to longer float charging life. Gas can be absorbed very well when the gas raised under normal conditions. Capacity will not be decreased because of reduction of electrolyte for as much as that special separator can keep well the electrolyte and press tightly positive activated substance to prevent from falling off. Consequently, long service life is promised.

5. High-Rate Discharging: Specially developed PMH series batteries match UPS market requirements. It’s outstanding beyond other similar products for its high-rate discharging performance.

6. Application Temperature: -15°C~50°C

7. Security: Sound safety is well set under normal operation by the explosion proof value special structure.

8. None Position Limitation: Battery can be installed on the right and inclined side or lying on the side.


Compliant Standards
1. GB/T19639-2005/ JIS C8702-2006/ IEC 61056-2002 
2. Passed ISO9001, ISO14001, OHSAS18001, UL, CE and TLC certificate.
