FAQ

(1) Check whether the electrical and battery contacts are clean, wipe it with a damp cloth if necessary, and install it according to the correct polarity after drying.
(2) Do not mix old and new batteries, and batteries of the same model but of different types cannot be mixed.
(3) The primary battery cannot be regenerated by heating, charging or other methods.
(4) Do not short-circuit the battery.
(5) Do not disassemble or heat the battery.
(6) The switch should be turned off after the electric appliance is used, and the battery should be removed if it is not used for a long time.

Generally, there is self-discharge inside the battery, which is commonly known as "power leakage". The storage time and storage environment of the dry battery, especially the temperature, have a greater impact on it. Generally, the longer the storage time and the higher the temperature, the more the power leaks. The higher the temperature and the greater the humidity, which will make the battery's conductive contacts rusty and not easy to use, and also increase the battery's power leakage, so the battery storage conditions are as follows:
(1) The battery storage area should be clean, cool and ventilated.
(2) The temperature should be between 10~30℃, generally should not exceed 40℃. The relative humidity should generally not exceed 65%.
(3) The storage time is not easy to be too long, and the storage should be neatly arranged, and the positive and negative electrodes should not be connected, which may cause a short circuit of the battery.

First, select the battery type and size according to the requirements of electrical appliances, and decide which type of battery to buy according to the power consumption and characteristics of electrical appliances, such as Walkman and electric toys generally use alkaline zinc manganese batteries, and the remote control and alarm clock generally use ordinary zinc-manganese batteries to meet the requirements.
