Household battery sizes are mainly divided into several common types, each with different sizes, capacities, and application scenarios.

Zinc nickel battery is a rechargeable battery (secondary battery) that utilizes the electrochemical reaction between zinc and nickel to store and release electrical energy.

Currently, many AA and AAA rechargeable lithium batteries on the market have a constant voltage output of 1.5V,

Primary and secondary batteries are commonly used types of batteries in daily life, and the main difference between them lies in their rechargeable nature and usage.

The capacity of zinc nickel batteries has a direct impact on their discharge curve. These impacts are mainly reflected in the duration of platform voltage, the rate of voltage drop at the end, and the total discharge time.

The main reason why zinc nickel batteries (Zn Ni) cannot use nickel hydrogen (NiMH) chargers is due to significant voltage differences and technical requirements between them.

Zinc-nickel batteries (Zn-Ni) have obvious advantages over lithium-ion batteries in some aspects, especially in terms of safety, environmental adaptability and cost-effectiveness.

Zn-Ni battery has a relatively flat discharge curve, which means they can provide a relatively stable output voltage throughout the entire discharge cycle

Zinc-nickel batteries (Zn-Ni) and nickel-metal hydride batteries (NiMH) differ in many aspects, including chemical composition, performance characteristics, application range, and their respective advantages and disadvantages.
