Nickel zinc (NiZn) battery is a new type of battery that can replace nickel metal hydride battery.

Usually used of. Compared with nickel-metal hydride and nickel-cadmium batteries, it has the characteristics of high voltage and strong discharge current. It has unparalleled advantages in digital cameras, flash bulbs and electric toys.

Nickel zinc batteries have high voltage. Compared with the previous AA battery, its voltage reaches 1.6V. It is much higher than the 1.2V nickel metal hydride battery and is more suitable for traditional appliances using 1.5V batteries. It makes the flash return faster. Make the digital camera run out of juice. Many nickel-metal hydride batteries used in digital cameras use only 30 percent of their power before powering down. Although the current (December 2010) AA model nickel-zinc battery capacity is only about 1300mAh, but its discharge energy has reached more than 8300 joules. It's not that different from eneloop, the best nickel metal hydride battery available today, which emits about 9, 000 joules.
