Melasta is a well-known brand to provide consumer product batteries. These are the features of the Ni-Zn battery.
1. Energy density of Nickel-Zinc batteries is 33% higher than that of standard (NiMH/Ni Cd) rechargeable batteries.
2. Melasta Nickel-Zinc batteries can offer up to 800 cycles
3. Melasta has multiple standard models such as AA, AAA,SC,C and D.
4. Environmental-friendly
5. Wide range of consumer applications including cameras, toys, watch, and remote control.
6. Low Self-Discharge
7. Melasta rechargeable NiZn aa batteries have passed UL and CE certification
Nickel–zinc cells have an open circuit voltage of 1.85 volts when fully charged, and a nominal voltage of 1.65 V. This makes Ni-Zn an excellent replacement for electronic products designed to use 1.5 V alkaline primary cells. MELASTA Nickel-Zinc batteries can offer up to 800 cycles, two times cycle life of NiMH batteries, so it can be an alternative to NiMH batteries for electric products. Due to their increased power rate and energy density features, users can expect a long time between charges and longer running time.
Melasta’s technology offers higher energy density than lead-acid batteries. The energy density of nickel-zinc batteries is 33% higher than that of standard (NiMH) rechargeable batteries.
Ni-Zn batteries are one of the most cost effective batteries as compared to Li-ion batteries. Melasta Ni-Zn AA battery can be recharged up to 500 times If we compare the life cycles with cost, then Ni-Zn batteries are 500 times cost effective than alkaline batteries.
In terms of environmental protection and health, Ni-Zn battery is the most environmentally friendly material in the market. Unlike the other hazard chemical raw materials, both Nickle and Zinc are recyclable while keeping their same chemical and physical properties. These batteries do not contain lead, cadmium, and mercury, so these are environment friendly. To overcome the global environmental issues these batteries can be replaced by NiMH Primary & Dry Batteries.
NI-Zn battery is more safe battery solution than Lithium-ion and lead-acid. These batteries do not have any explosive risk, that makes them recommended in applications such as transport and mobility, where physical safety is necessary.
Ni-Zn batteries can support fast charging technology. These batteries are recommended where higher charging and discharging rate is required for the application. These batteries retain thermal stability while charging and discharging at high rate.
