Analysis of battery damage

Trick 1: The battery has to be charged. The battery must be fully charged and then unplugged, and it cannot be used immediately. It should be placed for about ten minutes to let the battery cool before using it. This is helpful for the long-term use of the battery, and it must be handled with care when transporting and disassembling the battery, because if the battery is hit or bumped, it is very easy to damage the battery and affect the storage of its power. If the battery of an electric vehicle is fully charged, unplug it and do not charge it for a long time. This will damage the life of the battery very much.   Trick 2: You should charge it every day   It’s best to charge the battery every night, not every few days. If the battery is fully charged and not used for several days, all the points in the battery will be released, which is not conducive to the long-term maintenance of the battery. Charging every day is also good for the maintenance of the battery, and it can also ensure that the power is preserved. In this way, everyone can travel longer on electric vehicles.  The life of ordinary car batteries is generally about two years, and the life of maintenance-free car batteries is twice that of ordinary batteries. However, in real life, car batteries are often scrapped before they can be used to the design life. There are many reasons for battery damage, such as over-discharge, long-term storage without charging, no electrolyte or too high electrolyte specific gravity, contamination by dirt, etc. Now I will analyze some common causes and hope that you can use it correctly. Maintaining car batteries can help. 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 excessive current, too small contact surface, or poor contact during startup; too tight installation, violent prying during disassembly and assembly, will easily damage the pole and cause the battery to be scrapped. 2. The fixing is unreliable, and the vehicle will vibrate violently during driving, which will cause 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 the 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, mainly due to impure distilled water and metal containers such as copper and iron used in the preparation of the electrolyte. These impurities will form a 'small circuit' in the battery to accelerate the battery's self-discharge. 8. The wiping and maintenance are not timely, and the overflowing electrolyte will accumulate on the cover for a long time, causing the pole pile and pinch to corrode, generating oxides, and then forming a path on the cover, causing self-discharge. 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 vent holes of the battery. If it is not connected properly, the gas generated during use cannot be discharged, and the battery will explode due to excessive internal pressure. 11. The battery is left without charging for a long time after adding distilled water, which will cause the battery to self-discharge or damage the battery's polarity. 12. The charge capacity of the battery does not match the engine, causing early damage to the plate.
