Is battery repair really useful?

Of course, battery repair is useful, but it is definitely not possible to rely solely on the repair instrument. The repair instrument can only repair the sulfide of the battery, which accounts for only one tenth of the bad battery. Most of the broken plates and short circuits are realized by manual plate replacement technology. Therefore, to repair the battery, we must first learn to repair the battery manually. Most of my students came to me after buying a prosthetic appliance and felt cheated. I am repairing batteries in the army 16, and my classmates have already.
