Zinc nickel battery (Ni Zn) is a rechargeable battery with a nominal voltage of 1.6V (higher than the 1.2V of nickel hydrogen and nickel cadmium batteries), suitable for devices that require higher voltage or high current. The following are common application scenarios and precautions for it in households.
Applicable scenarios
High drain device
Due to the high voltage of zinc nickel batteries, they can provide stronger power for High drain devices.
Digital camera: Due to high voltage, it can provide faster startup and continuous shooting performance.
Flashlight/Strong Light Flashlight: Strong high-voltage driving ability, suitable for instantaneous high current discharge.
Electric toys: such as remote-controlled toy cars, four-wheel drive racing cars, drones, and other toys that require power support.
Replacing the traditional AA battery
Wireless keyboard and mouse/game controller: The battery life is better than alkaline batteries (especially in high current scenarios), but attention should be paid to voltage adaptability.
Clock/remote control: Low power devices are also available, but their cost-effectiveness may not be as good as alkaline batteries.
Special needs
Emergency equipment: such as disaster prevention radios and alarms, which are rechargeable and have stable discharge.
DIY projects: such as electronic circuit experiments, small robots, and other scenarios that require voltage support.
Advantages
Voltage advantage: 1.6V voltage is closer to alkaline batteries (1.5V) and has better compatibility than nickel metal hydrogen batteries (1.2V).
Environmentally friendly rechargeable: with a cycle life of 500+times, reducing waste battery pollution.
No memory effect: Charge as needed without emptying the battery.
Precautions
Compatibility issues
Some precision equipment (such as medical instruments) may be sensitive to voltage, and it needs to be confirmed whether they support nickel zinc batteries.
Avoid mixing with nickel hydrogen/alkaline batteries as it may result in uneven voltage.
Charger specific
It is necessary to use a matching nickel zinc battery charger (ordinary nickel hydrogen chargers may not charge properly, affecting battery performance).
Lifespan and Maintenance
Maintain 50% battery storage when not in use for a long time.
The nominal voltage of zinc nickel rechargeable batteries is 1.6V, which is closer to the voltage of alkaline batteries. Therefore, devices that can use alkaline batteries can basically use zinc nickel rechargeable batteries.
