Lead-acid battery repair methods and precautions for charging

Lead-acid battery repair method 1. Receive the battery and make a record, ask about the situation, and put a label on it. 2. Make a repair record and measure the open circuit voltage. 3. Regarding the battery in normal use, the voltage should not be lower than 11 volts. If it is lower than 11 volts, there is a possibility of disconnection. Such as long-term storage batteries can be. If the battery is higher than 9 volts, you can charge it first, if the battery is lower than 9 volts, add water first to repair, and then charge when the voltage is higher than 9 volts. 4. If the battery becomes hot during charging. It shows that the battery plate is softened. If the battery is slightly softened, it can be repaired, and if it is severely softened, it cannot be repaired. Slight heating can stop charging and wait for the temperature to drop before charging. 5. Repair the battery after replenishing and charging. The repair time should be at least 24 hours. If the capacity is large, the repair time can be added appropriately. 6. After repairing, it is necessary to carry out replenishing and charging. The replenishment and charging time is generally not too long. Some may overflow as soon as it is hung, and some may overflow for a few minutes. No matter the length of time, this step must be carried out. Precautions for charging lead-acid batteries 1. During the charging process, check and record the electrolyte density and terminal voltage of each cell in time. In the early and middle stages of charging, check and record once every 2h; when approaching the end of charging, check and record once every 1h. If it is found that the terminal voltage and electrolyte density of individual cell batteries rise more slowly than other cells, or even if the change is not clear, stop charging, find out the reason in time, eliminate the fault, or perform low-current charging alone to restore it to normal Then, recharge with other batteries. 2. During the entire charging process, the temperature of each cell must be measured at any time, so as not to affect the performance of the battery if the temperature is too high. When the temperature rises to 45℃, the charging should be suspended, and the charging should be continued when the temperature drops below 35℃. The temperature can also be cooled by air cooling or water cooling. 3. Ventilation equipment should be installed in the charging room. During the charging process, the ventilation equipment should work continuously to discharge harmful gases, beware of explosions, and try to beware of harm to the human body. 4. The charging equipment and the battery to be charged should not be placed in the same room. When charging, connect the rechargeable battery according to the regulations, and then turn on the power switch. When stopping charging, turn off the power switch first, and then remove the charged battery. The wire connection must be reliable and prevent sparks from appearing.
