The battery usage time far exceeds the normal usage time. The battery can generally be used for more than 1 year in normal use. It can be judged whether the battery is scrapped according to the conditions of use and operating conditions. When the following phenomena occur, it can be judged that the battery has reached the final working life and should be scrapped.
1. Severe heat when the battery is charging, and the casing is deformed. When the plate of the battery softens and deforms, the active material falls off, and the electrolyte in the pool becomes black, and it cannot be repaired when it is seriously invalid. At this time, the battery charges and discharges quickly.
2. When the life of the battery is over, use a multimeter and ammeter to test its voltage and current. Their values u200bu200bare very low, the performance of the battery decreases, and a short circuit may occur in the battery , If there is an open circuit, replace the battery with a new one in time.
3. The actual discharge capacity of the battery is less than about 60% of the rated capacity, and the battery whose performance cannot be restored after repair must be scrapped. Generally, when the capacity of a battery decays to about 60%, its performance will be greatly attenuated, and it will quickly lose its charge and discharge capabilities. It will be fully charged in a short time and quickly discharged. It cannot store electricity and discharge. The time is short.
