Product Features ：  
Plate alloy design:   Adopted with   lead-calcium-chalcopyrite multi-alloy, small self-discharge rate . no need to add water.  
1. Plate: Positive plate with tube structure, active material is not easy to fall off, long battery life, reliable performance. The negative plate is coated with a paste structure.  
2. Separator : PVC-SIO2 separator , effectively avoid the occurrence of short-circuit phenomenon.  
3. Battery slot, cover: made from resistive ABS shell, a unique slot cover sealing technology, with handsome in appearance, solid structure, reliable sealing and so on.  
4. Sealing structure: slot, cover the use of adhesive seal, pole parts with rubber ring seal and epoxy resin double seal structure, to ensure no leakage.  
5. Battery performance: small size, light weight , high capacity, the first discharge rate up to 95% or more, with high reliability in the harsh use of environmental  
6. Battery connection: Between the batteries using copper cable connection, cable cross-sectional area, the pressure drop is small, the surface of the use of insulation plastic, engage in good corrosion, in the installation and use to prevent the occurrence of short-circuit phenomenon.  

Application : Telecommunications, mobile, network, railway, airport and other communications, signal system backup power supply. Power system, nuclear power plant standby power supply. Solar energy, wind power generation energy storage. UPS, medical equipment, emergency lighting and other backup power supply.  

Service Life :  
OPZV fixed tube colloidal battery series is developed in accordance with the German DIN standard a high-performance, long life new products, 20. C under the conditions of operation to ensure that the float to achieve more than 20 years, 80% DOD cycle "life can reach more than 2000 times."  

Compliant Standards:
