A brief description of the inspection and maintenance methods of the battery

After using a charging machine to charge the battery, the service life of the battery is calculated. The good charging and maintenance of the battery later can effectively extend the service life of the battery. Battery in use should regularly check the electrolyte height, timely battery storage status check and supplement. The maintenance work of the battery is relatively simple, and it can effectively extend the service life of the battery by doing a good job of supplementing the electrolyte, cleaning the battery and the pole pile, and controlling the specific gravity of the battery. Due to the widespread use of maintenance-free batteries, batteries generally do not need to be maintained under normal working conditions.

1. Clean the outside of the battery

2. Check battery level

3. Replenishment of electrolytes

4. Check the specific gravity of the electrolyte.

According to the different performance of the battery during charging inspection of the charging machine, the internal failure of the battery and its causes are identified.

(1) Normal state. When charging the battery, the voltage of the battery and the specific gravity of the electrolyte increase according to certain rules, and the electrolyte temperature is not high. This shows that the technical state of the battery is normal, but it belongs to excessive discharge and should be charged.

(2) Sulphur state. When the internally vulcanized battery is charged, the initial single-cell voltage can rise to about 2.8 V, and the electrolyte temperature is also high. As the charging continues, the single-cell voltage will drop to 2.2 V after a few hours, and then slowly rise and good. Battery charging law is the same. For batteries that are severely vulcanized internally, the voltage of a single-cell battery will be higher than 2.8 V, and the specific gravity of the electrolyte will not increase. At the beginning of charging, the battery will bubble up.

(3) The release of the active substance. When the battery that the active substance falls off seriously is charged, the electrolyte is turbid, the battery capacity is reduced, the charging time is shorter than the normal battery, and the phenomenon of the end of charging such as electrolyte boiling will also appear in advance.

(4) Self-discharge. Self-discharge battery, charging time is longer, electrolyte specific gravity and end voltage rise slowly. If there is a serious short circuit inside the battery, no matter how long the charging time is, the specific gravity of the electrolyte and the end voltage will not rise, and there will be no bubbles in the battery. The electrolyte looks like a stagnant water.
