Zinc batteries are a reliable source of energy for low-energy appliances. In equipment such as remote controls for television, clocks, smoke detectors, and torches, Zinc batteries should be used due to low energy consumption. However, charging these batteries could surely be a headache. But, we will make it easy for you. Read till the end of this article, to find out how should one charge Zinc Batteries.
How To Charge Zinc Batteries?
Zinc batteries can be charged using the Constant Current (CC) and Constant Voltage (CV) methods. The rated capacity in Amp Hours (Ah) is dependent on the charge rate of C/4 and the discharge rate.
Steps To Charge:
- Charge the Zinc battery at a minimum constant current rate of C/4 Amps until the battery voltage is 1.9 volts per cell. But, remember the volts per cell shall not increase 1.9.
- Continue charging the Zinc battery until the charge current declines to C/40 amps.
- The Charging process stands completed now.
- After the charging is finished, disconnect the charger.
The battery must stop charging at 1.9V/cell. However, we found a surprising fact from the world of google. You can charge two NiZn cells in series using the LiFePo4 system, which will cut around 3.8V/cell.
Some points must be kept in mind:
- Zinc batteries are rated at C/4 to 10C discharge rates.
- The discharging capacity of the battery is 1.25 volts per cell.
- Recharge the Zinc battery only when the open-circuit voltage drops to 1.77V/cell.
So, there you have it folks, everything you were curious to know about the ZInc Batteries and how to charge them.
