After charging the battery with the charger, the service life of the battery begins to be calculated. The good battery charging and maintenance in the later stage can effectively extend the service life of the battery. The battery should be regularly checked for the height of the electrolyte during use, and the battery storage condition should be checked and supplemented in time. Battery maintenance work is relatively simple, do a good job of electrolyte supplement, battery and pole cleaning and battery specific gravity control, can effectively extend the battery life. Due to the widespread use of maintenance-free batteries, batteries generally do not require maintenance under normal operating conditions.
1. Clean the battery outside
2. Check the battery level
3. Replenish electrolyte
4. Check the specific gravity of the electrolyte.
According to the different performance of the battery during the charging test of the charger, the internal fault of the battery and its cause are determined.
(1) Normal state. When charging the battery, the battery voltage and the specific gravity of the electrolyte rise according to a certain rule, and the electrolyte temperature is not high. This indicates that the technical state of the battery is normal, but it is too much discharge and should be charged.
(2) Vulcanization state. When the internal vulcanized battery is being charged, the initial cell voltage can rise to about 2.8V, and the electrolyte temperature is also high. As the charging continues, after a few hours, the cell voltage will drop to 2.2V, and then slowly rise and Good battery charging rules are the same. In the internal severely vulcanized battery, the voltage of the single cell will be higher than 2.8V, and the specific gravity of the electrolyte will not rise. At the beginning of charging, the battery will bubble.
(3) The active substance falls off. When the battery in which the active material is severely detached is charged, the electrolyte is turbid, the battery capacity is lowered, the charging time is shortened compared with the normal battery, and the phenomenon that the charging of the electrolyte is finished is also advanced.
(4) Discharge yourself. The self-discharged battery has a longer charging time, and the specific gravity and terminal voltage of the electrolyte rise slowly. If there is a serious short circuit inside the battery, no matter how long the charging time is, the specific gravity and terminal voltage of the electrolyte will not rise, and there is no bubble in the battery. The electrolyte is like a pool of stagnant water.
