Determine whether the 18650 lithium battery soaked in water can continue to be used.
Here is the method to determine whether the 18650 lithium battery soaked in water can continue to be used:
1. Appearance inspection
Firstly, check the appearance of the battery for any obvious deformation, corrosion, or other damage. If the appearance of the battery is normal, the next step of inspection can be continued.
2. Battery temperature
Lightly touch the battery casing with your hand. If you feel abnormally hot or cold, it may indicate that the interior of the battery has been damaged and should not be continued to be used.
3. Charging test
Use a charger to charge the battery and observe if the charging is working properly. If there are abnormalities during the charging process (such as significantly slower charging speed, battery overheating, etc.), the battery should be stopped from use.
4. Discharge test
Connect the battery to the device for discharge testing and observe whether the battery can supply power normally. If the battery cannot provide sufficient power or there are abnormal situations during the discharge process, the use of the battery should be stopped.
