What are the common causes of battery damage?

1. The size of the pole pile and the chuck do not match. When the installation is too loose, it is easy to burn the pole due to the excessive current when starting, the contact surface is out of order and the contact is poor. The pole is easily burned when the installation is too tight, and the pole is easily damaged during disassembly and assembly, which will cause the pole to be damaged and the battery will be scrapped. 2. The fixing is unreliable, and the vehicle vibrates severely during driving, causing the rubber seal, shell and cover to crack. 3. Excessive charging current will cause the active material on the plate to fall off prematurely and shorten the service life of the battery. 4. The starting time is too long, causing the battery to discharge rapidly, causing the plate to bend and the active material to crack. 5. Long-term storage or use under the condition of insufficient charging to vulcanize the electrode plate. 6. The electrolyte level is lower than the electrode plate, so that the electrode plate is exposed to the liquid surface and oxidized by contact with air. During driving, the electrolyte fluctuates up and down and comes into contact with the oxidized part of the electrode plate, causing the electrode plate to vulcanize. 7. The electrolyte contains impurities. The important thing is that the distilled water is impure and the metal containers such as copper and iron are used when preparing the electrolyte. These impurities will form a small circuit in the battery to accelerate the self-discharge of the battery. 8. If the wiping and maintenance are not timely, the overflowing electrolyte will accumulate on the cover plate for a long time, causing the pole piles and clamps to corrode, and oxides will appear, and then a path will be formed on the cover plate, and the phenomenon of self-discharge will appear. 9. The new battery will not be charged for the first time or directly charged with high current, which will shorten its service life. The new car battery can be installed and used only after the electrolyte is filled and the low-current method must be used for the first charge. 10. Ignore the air vent of the battery. If it is not turned on at the correct time, the gas in use cannot be discharged, and the battery will explode due to excessive internal pressure.
