Battery leakage is actually a natural discharge.
First, it is related to the humidity of the environment, because the humidity of the air is large, the conductivity is enhanced, and electric leakage is easy.
Second, the temperature is to promote the chemical reaction of the battery, of course, the higher the temperature, the more intense the reaction, and the battery specification has a suitable range of use of the battery. Generally, the range of 0 degrees - 40 degrees is best.
It is also related to use and storage.
Different battery specific maintenance methods are different, please refer to the specific introduction in the instruction manual.
1. Household dry batteries, if not used temporarily, poorly stored, there will be leakage. If a thin layer of candle oil can be applied to the negative electrode of the battery and then left in a dry place, it can effectively prevent leakage.
2. Unused dry batteries will run slowly. If you store the dry battery in the refrigerator, you can extend its life.
3. When the flashlight is not in use, the battery can be reversed and placed in the flashlight to slow down the natural discharge of the battery and prolong the battery life. At the same time, it can avoid the battery being discharged due to forgetting, the battery becomes soft and the cavity of the flashlight is rusted.
