no.
a general term for repairing secondary rechargeable batteries with degraded or invalid performance by physical or chemical means. Through repair, the capacity of the battery can be restored, the service life of the battery can be prolonged and the performance of the battery can be improved, which is called battery repair.
Our storage batteries usually suffer from sulfation, water loss, short cell, plate falling off, etc. According to the inventor of the battery repair patent, at present, the battery is easy to be repaired because of water loss and battery vulcanization, and problems such as battery grid breakage and electrode plate falling off require high technical content, so it is generally not recommended to repair it.
Note for electric vehicles:
1. Under normal circumstances (people are not often taken, and climbing hills all day), it is best to drive to 6%-7% of the longest driving range in the manual, which can not only avoid the early capacity loss of the battery, but also avoid overdischarge.
2. If you often take people and climb hills, it is recommended that you drive to 5% of the longest continuous mileage in the manual before charging.
3. If you drive very little at ordinary times and don't drive 6%-7% of the longest continuous mileage in a week, it is recommended to charge it once.
4. If you go out or stay closed for a long time, it is recommended to charge once a month.
