When we use the battery, there will be some small faults more or less. Let me explain to you the common faults and treatment methods of the battery, as well as the use faults that the battery is prone to encounter in use?
The general fault handling of the battery includes: voltage balance deviating from the normal range (observation after forced equalization), abnormal float current (check whether the battery cell voltage is abnormal and whether the battery is hot), and check discharge (do it after equalizing for 10 hours). rate or 3-hour rate capacity to determine whether the capacity is insufficient), leakage of liquid from the safety valve (not the leakage of liquid from the inside of the battery), etc.
When a charged battery is stored for a long time, its capacity will gradually decrease and become discharged. This phenomenon is called self-discharge, and this phenomenon is unavoidable. Even if the battery has not been used, it will cause self-discharge due to chemical and electrochemical reactions inside the battery. Now the self-discharge of Xili lead-acid batteries is described as follows:
A. The chemical factor, whether it is the active substance of the positive plate (PbO2) or the negative plate (Pb), needs to be decomposed or gradually reacted with sulfuric acid (electrolyte), and converted into a relatively stable lead sulfate. This process is self-discharge.
b. Due to the presence of impure substances in electrochemical factors, local circuits will be formed inside the battery or redox reactions will occur with the two poles, resulting in self-discharge. Due to the extremely low impurity content of the Li-energy battery electrolyte, the self-discharge amount is very small, which is due to the strong retention characteristics of the battery.
(2) The self-discharge of the battery is closely related to the storage temperature
Therefore, the battery should be charged immediately after discharge, and the battery should not be put on hold for a long time after discharge; the battery that is not needed should be recharged repeatedly after being put on hold for a period of time until the capacity returns to the level before storage.
