AAA Battery Manufacturing for Eco-Friendly Solutions IntroductionThe demand for AAA batteries continues to grow as they power a wide range of devices, from remote controls and flashlights to digital cameras and wireless keyboards. However, the environmental impact of battery production and disposal...

​Rechargeable NiMH batteries typically have a rated voltage of 1.2V, which is determined by their nickel-metal hydride chemistry. The positive electrode of a NiMH battery uses nickel hydroxide, and the negative electrode uses a hydrogen storage alloy. During the charge and discharge process, hydrogen ions migrate between the positive and negative electrodes, generating a stable voltage plateau of 1.2V. This voltage is slightly lower than that of disposable alkaline batteries, but NiMH batteries can be used for a long time through cyclic charge and discharge.

​The international standard designations for AA batteries follow the IEC (International Electrotechnical Commission) classification system, officially designated as LR6 (alkaline) and HR6 (rechargeable nickel-metal hydride).

Compared to ordinary dry-cell batteries, alkaline batteries offer advantages such as durability, high current capacity, long storage life, and corrosion-resistant casings.

Alkaline batteries are typically made from environmentally friendly materials free of mercury, cadmium, and other harmful heavy metals.

To ensure optimal performance and safety when using alkaline batteries, please note the following:

Check device performance: If you notice a decline in performance in a device using alkaline batteries, such as a sluggish remote control or dim flashlight, this may indicate low battery charge and you should consider replacing the batteries.

When temperatures exceed 40°C, the internal chemical reactions of alkaline batteries accelerate, leading to increased self-discharge and a rapid decrease in charge.

Common battery recycling methods include secondary use, disassembly and recycling, recycling, landfill, and incineration.

Alkaline batteries are disposable, meaning they cannot be recharged after use. This is because the chemical reaction within alkaline batteries is irreversible during discharge; once the reaction is complete, the battery can no longer generate electricity.

Alkaline batteries are highly suitable for a wide range of applications due to their high performance and long lifespan. Here are some common applications where alkaline batteries are used:
