How to repair a leaking lithium battery pack?

How to repair a leaking lithium battery pack? The following Pederui technicians will answer your questions:

Ordinary hot melt adhesive strip repair. This is a heat gun. Blow tape. Repair cracks. However, the disadvantage of this method is the high temperature. Not easy to grasp. It will damage other plastic casings, deformation, etc. Also, it can only be done locally. Small points such as terminal leakage cannot be done.

I basically use room temperature vulcanized silicone rubber to seal leaking batteries. It should be possible to use epoxy. In short, it is very sticky.

However, please note 1. The glue composition cannot contain conductive impurities. 2, must be acid-proof.

Remember to replenish water after repairing. Adjust the weight. Don't let broken units fall behind. There are three reasons that affect battery life: manufacturing quality, charger mode and parameter settings, and user usage. A large number of experimental data show that the performance degradation of lead-acid batteries is as follows: the battery loses water seriously; the performance of some batteries in the whole group is particularly poor; the internal resistance is very large, and the voltage during charging is very high, so it cannot be charged. In addition, the number of lead-acid batteries used in UPS in my country is large, and changes in use conditions or power supply conditions will affect the service life of the entire battery. Using effective repair technology to extend the service life of valve-regulated lead-acid batteries for electric bicycles and UPS can greatly reduce costs, save resources, and be conducive to environmental protection.

The use of variable amplitude pulse charging technology to repair old VRLA batteries has achieved good results. The charging method is: start high-current constant-current charging, and automatically switch to the gap pulse charging of negative pulses according to the characteristics of battery internal resistance and voltage change. With the breakdown of the lead sulfate layer on the surface of the repaired battery plate, the voltage drops and the charging current also changes.

     In the later stage of battery repair and charging, the ratio of positive and negative pulse power is gradually reduced, and the average current is reduced, which can prevent damage to the plate caused by long-term high-current charging, and can also ensure that the entire battery is fully activated and has the same internal resistance. In order to achieve a better repair effect, the charging current should not be less than 0.3CA, the negative pulse current should be about 0.2CA, and the time and interval of positive and negative pulses should be appropriate.
