 Float charge：
Float voltage of FM and GM model is 2.40V/cell and 2.35V/cell respectively.
F10 Charge with 0.1C20 to 2.3V then with constant woltage at 50% C20 DOD and 100% C20 DOD.
F11 Charge with 0.1C20 to 2.3V then with constant woltage at 50% C20 DOD and 100% C20 DOD.
Float voltage of FM and GM model is 2.40V/cell and 2.23V/cell respectively at 25℃ The float voltage should be corrected with –3mV/℃/cell coefficient when the temperature is not equal to 25℃.
F12 Relationship between float woltage and temperature of GM model battery.

Charge voltage during cycle use：
The battery should charge with constant voltage and limited current range of 0.1-0.2CA (C:FM model C20 , GM model C10)during cycle use .The charge voltage of FM and GM model is 2.4V/cell and 2.35V/cell respectively at 25℃ . The charge voltage should be corrected with –4m V/cell coefficient when the temperature is not equal to 25℃ .Timing/automatic limited current charge equipment could be used to prevent overcharge.

Equalizing eharge：
This method could charge with constant current ,then 2.40V/cell FM model ,2.35V/cell GM model,Charge time is dependent on DOD .see the following table:
