There are several key points to note when storing and using carbon-zinc batteries

Storage precautions
1. Temperature control: Carbon zinc batteries should be stored in a dry, cool place, away from direct sunlight and high temperature environment. The suitable storage temperature is generally between 15°C and 25°C. High temperature will accelerate the self-discharge of the battery and the evaporation of the electrolyte, resulting in reduced capacity and shortened service life
2. Humidity control: It is also important to keep the storage environment dry. High humidity increases the risk of battery leakage, as a humid environment may cause corrosion of the battery casing.
3. Avoid over-discharge: Before storage, make sure that the battery has a certain amount of power to avoid over-discharge. A fully discharged battery is prone to leakage and deterioration of internal chemicals.
4. Prevent short circuits: Make sure that the positive and negative poles of the battery do not touch metal objects to prevent short circuits. It can be stored in the original packaging or a separate plastic box.

Precautions for use
1. Correct installation: When installing the battery in the device, make sure that the positive and negative poles are correctly connected. Incorrect polarity connection can cause the battery to overheat, leak or even explode.
2. Avoid mixing: Do not mix batteries of different types, brands, and newness. Mixing batteries will cause uneven battery voltage, increasing the risk of leakage and overheating.
3. Regular inspection: Regularly check the batteries in use and batteries in storage, especially those that have not been used for a long time, to check for leakage, swelling or corrosion. Once a problematic battery is found, it should be replaced and properly disposed of.
4. Avoid over-discharge: Carbon zinc batteries should avoid over-discharge when in use, especially when used in high-power devices. Over-discharge will cause an imbalance in the chemical reaction inside the battery, increasing the risk of leakage and battery damage.

Handling precautions
1. Environmentally friendly recycling: Discarded carbon-zinc batteries should be recycled and disposed of in accordance with local environmental regulations, and should not be discarded at will. Carbon zinc batteries contain metals such as zinc and manganese, which have a certain impact on the environment.
2. Safe handling: If the battery is found to be leaking or other abnormal conditions occur, gloves should be worn for handling to avoid direct skin contact with the electrolyte.
By paying attention to these storage and use matters, the service life of carbon-zinc batteries can be effectively extended to ensure their safety and reliability. At the same time, proper recycling and disposal also helps to reduce environmental pollution.
