What are the solutions to common failures of Panasonic batteries?
There will inevitably be some minor faults in the use of Panasonic batteries. In fact, as long as we have a simple understanding of Panasonic batteries, we can easily solve the problems of Panasonic batteries. So let Xiaobian introduce the solutions to common faults of Panasonic batteries for you today.
The general fault treatment of storage battery includes: deviation of voltage balance from normal range (observation after forced charging), abnormal floating charge current (checking whether the cell voltage is abnormal, whether the battery is hot), checking discharge (10-hour rate or 3-hour rate capacity after charging, judging whether the capacity is insufficient), leakage of safety valve (non-electric discharge). Leakage from inside to outside of the pool, etc.
When a charged battery is stored for a long time, its capacity will gradually decrease and become a state of discharge. 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 within the battery. The self-discharge of lead-acid batteries is described as follows:
A. Chemical factors, whether the active substance of the anode (PbO 2) or the cathode (Pb), need to be decomposed or reacted with sulfuric acid (electrolyte) step by step, and transformed into more stable lead sulfate, which is self-discharge.
B. Due to the presence of impurities, electrochemical factors can form local circuits or redox reactions with the two poles, resulting in self-discharge. Because of the very low impurity content, the self-discharge capacity of the electrolyte of the power battery is very small, which is due to the ultra-strong retention characteristics of the battery.
(2) There is a close relationship between self-discharge and storage temperature of batteries.
Therefore, Panasonic batteries should be charged immediately after discharging, and the batteries should not be shelved for a long time after discharging; unnecessary batteries should be re-charged after shelving for a period of time until the capacity restores to the pre-storage level.
