INITIAL CHARGING PROCESS
Battery Voltage (Open
Circuit Voltage, OCV)
Process
<24V
Discharge the battery at the one-hour rate to 20V. Recharge at
constant potential (CP) of 28.2 to 29 volts until the charge rate
drops to 1A. Then charge at constant current (CC) of 1A for 12
hours. Discharge the battery at the one-hour rate to 20V (see
Appendix A). The battery must achieve at least 100% (1 hr) of
this rating.
- If the battery passes, recharge it using CP and CC method
- If not, repeat CP and CC charge followed by one more
discharge. If the battery fails to meet capacity, call Teledyne
Tech Support for further direction.
24V-25.5V
Discharge at one-hour rate to 20V (see Appendix A) – then
recharge at constant potential of 28.2 volts to 29 volts until
charge current drops to 0.5A or less.
> 25.5V
Charge at constant potential of 28.2 volts to 29 volts until
charge rate (current) is equal to or less than 0.5A
