I can learn battery maintenance technology here. I am a military technician. I have been repairing batteries in the army for 0/6 years, mainly by hand. I went home to find a job and opened a battery repair shop. My students are all over the country and have made great achievements. Most of my students came to me after buying a maintenance instrument, because the maintenance instrument can only repair the battery vulcanization, which only accounts for one tenth of the bad batteries. 6/ 10' s broken grid and short circuit must be realized by manually opening the cover and replacing the electrode plate. After returning home, I visited the manual repair technology in six places across the country and found that the military technology is still the most advanced, about five years earlier than the local ones.
