Simple analysis of several repair methods of lead-acid batteries

1. The lead-acid battery pole post is ablated or broken. When the lead-acid battery pole post is ablated or broken, it can be repaired by the wire planting method. First cut the damaged pole pile from the root, drill a 5mm deep 15mm hole in the center of its section, and screw in an m6×30 hexagonal screw. Put the horn tube made of iron sheet on the pole pile, pour the heated and melted lead water, and remove the horn tube after cooling. 2. If cracks in the lead-acid battery shell and upper cover are found in time during driving, the leakage should be plugged first. Pour the battery to the side that does not leak, dry the leaking electrolyte, dig out some sealing material on the battery cover, and heat it on the exhaust pipe to make up for the leak. If it is a long strip crack, use a hacksaw to cut the v-shaped groove before repairing it. For small cracks, adhesives can be used. The method is to first heat the cracks locally, and then use a knife to cut the cracks into small v-shaped grooves after they become soft, and then put the prepared resin cement into the area to be repaired and flatten it with paper, and put it in the room after it hardens by itself. be usable. 3. Lead-acid battery plate vulcanization Lead-acid battery plate vulcanization is mostly caused by the formation of a coarse-grained lead sulfate on the plate when the battery is in a discharge or half-discharge state for a long time. If the vulcanization is not serious, a small current and long-term charging method can be used to restore the active material. The operation method is as follows: first discharge the battery according to the 20h discharge rate, pour out all the electrolyte, rinse it with distilled water several times, and then pour the distilled water to the standard liquid level. Charge with the charging current of the second stage of the initial charging, and measure the density of the electrolyte at any time, and stop charging when the density increases to 1.15g/cm3. Then pour out all the electrolyte in each cell, pour in distilled water, and continue charging. Repeat this many times until the density of the electrolyte no longer increases. Finally, discharge it once, then fully charge it, and adjust the electrolyte density to the desired value. The capacity of the battery after desulfurization charging should be restored to more than 80% of the rated capacity. Otherwise, you should charge and discharge several times to solve the problem. 4. The active material on the plate of the lead-acid battery falls off. When the active material of the lead-acid battery does not fall off too much, it can be used continuously after removing the sediment. 5. The sealing glue of lead-acid battery is broken. When the sealing glue of lead-acid battery is broken, if the crack is small, it can be hot-smelted with a hot soldering iron. If the crack is large and the electrolyte leakage is serious, it should be removed and re-poured. In order to reliably combine the sealing material with the shell, the pouring place should be scrubbed with cotton yarn dipped in alkaline water to remove the acid. 6. Lead-acid battery is disconnected. If a single cell of the lead-acid battery is disconnected, a sufficiently thick wire can be used across the disconnected cell for temporary use. 7. Lead-acid battery plate short-circuit occurs. Lead-acid battery plate short-circuit occurs. This phenomenon is mostly caused by damage to the separator or too much sediment on the bottom. If the partition is damaged, disassemble the battery and replace the partition. If only one partition of a single grid is damaged, this single grid can be taken out separately for repair. If there is too much sediment, you should pour out the electrolyte, rinse it with distilled water repeatedly, and then charge it.
