1.Brief introduction
This kind of cell is used as DC power sources for highvoltage breakers and protecting relays in the substationwith working voltage below 220Kv,and also as emergencypower sources for planes,ships and vehicles.

2.Specific properties
Totally sintered,high quality performance.
Maintenance-free,no need to add electrolytic liquid in use.
Long recylce life:ten years of life in the state of low current charge.

3.Technical parameters
Charge retention

After charging,the cell shall be stored on open circuit for 28 days.The average ambient temperature shall be 20??5??.The cell shall be discharged to 1.0V at a rate of 0.2C(A).The duration of discharge after storage shall be not less 3h15min.
