How to maintain and repair the ternary polymer lithium battery?

How to maintain the ternary polymer lithium battery? 1. First, the new battery is fully charged. If our newly purchased battery should be fully charged before use, the charging voltage is generally between 4.16v and 4.2v, and should not exceed 4.23v. The battery must be discharged after it is fully charged. It is best to maintain a small and medium current during the discharge process. The final job is to carry out the charge and discharge cycle back and forth according to the above process, and it can be used after three times. This is the maintenance of the activation of the new battery. This process is very important. The service life of the polymer lithium battery after activation will be much longer. 2. Prevent overcharging. There are hard requirements for the choice of charger. If some chargers do not have the function of turning off the power after the battery is fully charged, the ternary lithium battery will not stop charging after being fully charged, which will cause certain harm to the battery. In addition, after long-term use of the charger, the battery will not stop charging after being fully charged. Therefore, when the lithium polymer battery is being charged, someone needs to be watching. In order to avoid battery failures, explosions and injuries. 3. Prevent excessive discharge. If the ternary polymer lithium battery is over-discharged, it will have a direct impact on the battery life. If the battery capacity is 2200mAH, the maximum limit is to charge 1600mAH after the battery is discharged. The general battery is best discharged with a capacity of 1300mAH to 1600mAH. If you follow this charging and discharging method, the life of the battery will be prolonged. 4. Prevent full power storage. If the battery is fully charged, it cannot be stored for more than three days when it is fully charged. After a week of storage, the battery will swell directly. There is also a possibility that the battery will not swell at the time, but in the next few times After the battery is charged, the phenomenon of swelling will appear. If the battery is not used for a long time, it is best to discharge the battery to 3.85v to keep the battery in the best condition. How to repair ternary polymer lithium battery? ▲The ternary polymer lithium battery voltage is lower than 2.7V, you can use the charger to charge the battery. After ten minutes, if the battery voltage rises, you can continue to charge until the charger prompts to be full, and then look at the full voltage. If the full battery voltage is 4.2V, it indicates that the battery is normal. If the full voltage is much lower than 4.2V, it means the battery is damaged. ▲If you measure the battery and the battery has no voltage, there are two situations at this time. One is that the battery is good, and it is caused by long-term storage. This kind of battery has a certain chance to recover. Generally, a lithium battery pulse activator is used to short the battery. Charge repeatedly over time. The repair cost is not low, it is better to replace it; another possibility is that the battery is completely worn out, the battery diaphragm is broken, and the positive and negative electrodes are short-circuited. At this time, you can only buy a new one. Disclaimer: Some pictures and content of articles published on this site are from the Internet. If there is any infringement, please contact to delete.
