Charging Instructions for Nickel-Zinc (NiZn) Batteries
ZincFive NiZn batteries are charged using a Constant Current (CC) and Constant Voltage (CV) method. The rated battery capacity in Amp Hours (Ah) is based on a C/4 charge and discharge rate.
Ambient (25°C) charge:
Charge the NiZn battery at a minimum Constant Current rate of C/4 Amps until the battery voltage reaches 1.9 volts per cell. Do not exceed 1.9 volts per cell.
Continue to charge until the charge current declines to C/40 amps. The NiZn battery charge is now complete. Disconnect the charger.
Do not trickle or float charge NiZn batteries
Battery self-discharge is approximately 3% per month dependent on temperature and battery state of charge
Recharge the NiZn battery when open circuit voltage declines to 1.77 volts per cell.

Discharge instruction for NiZn batteries:
ZincFive NiZn batteries are rated for a C/4 to 10C discharge rates.
Discharge battery cut-off voltage is 1.25 volts per cell.
