If the 18650 lithium battery wear test is damaged, it will basically happen that the battery voltage does not go up and the storage capacity decreases. We can directly measure it with a DC voltmeter during the test, if the voltage on both sides of the battery pack If it is lower than 2.7V, or if the voltage is not tested at all, it is concluded that it is damaged. If the battery voltage is lower than 2.7V, the repair we can do is to use a charger (4.2V) to charge the battery. After about 10 minutes, if there is a voltage increase, we need to do It is to continue to charge it, and then fully charge the voltage after the battery is fully charged. If the full battery voltage is 4.2V, it means that the battery is normal. The key is that it may consume too much power during the last use, causing the battery to be completely cut off. If the full-charge voltage is much lower than the 4.2V value, it is concluded that our battery has been damaged. If the battery has been used for a long time, the battery can be replaced in time, otherwise there is no other way to repair it.
