Standard Charge process :
Charging shall consist of charging at a 0.2C constant current rate until the battery reaches 29.2V.
The battery shall then be charged at constant voltage of 29.2V volts while tapering the charge current.
Charging shall be terminated when the charging current has tapered to 0.05 C5A.
Charge time: Approx 7.0h,
The battery shall demonstrate no permanent degradation when charged between 5 ºC and 45 ºC.
standard Discharge :
Battery shall be discharged at a constant current of 0.2C to 20.0V @ 20º ± 5C
The batteries should be stored at room temperature, charged to about 30% to 50% of capacity.
We recommend that batteries be charged about once per three months to prevent over-discharge.
Because batteries utilize a chemical reaction, battery performance will deteriorate over time even if stored for a long period of time without being used. In addition, if the various usage conditions such as charge, discharge, ambient temperature, etc. are not maintained within the specified ranges the life expectancy of the battery may be shortened or the device in which the battery is used may be damaged by electrolyte leakage. If the batteries cannot maintain a charge for long periods of time, even when they are charged correctly, this may indicate it is time to change the battery.
