1. Battery consumption: battery voltage does not go and reduce capacity. The pen is used to measure the voltage gauge, if the voltage of the 18650 battery is below 2.
7V or no voltage. Indicates that this battery or battery pack is damaged. Normal voltage 3.
0V ~ 4.2V (typically 3.0V battery is closed, 4.
2V battery voltage is full of electricity, and 4.35V). 2.
The battery voltage is lower than 2.7V, and the battery can be charged with the charger (4.2V).
After ten minutes, if the battery voltage has a rebound, it can continue to charge the charger prompt, and then look at the fillet voltage. If the full charge voltage is 4.2V, the battery is normal, and it should be that the last use consumes too much power, the battery is closed.
If the full charge voltage is much less than 4.2V, it indicates that the battery is damaged. If it is a long battery, it can be determined that this battery life is in, the capacity is basically exhausted.
Be replaced. Basically, there is no way to repair. After all, the lithium-ion battery is life, not unlimited.
3. If the 18650 lithium-ion battery pack is measured, there is no voltage, there are two cases, one is that the battery is good, long-term loss is stored, this battery has a chance to recover, generally with lithium ion batteries Pulse activator (lithium-ion battery charge and discharge enforcement) to charge the battery for a short time, it is possible to repair. General repair costs are not low, or buy new translations.
Another possibility is that the battery is completely depleted, the battery diaphragm breakdown, the positive and negative short circuit. There is no way to fix this, you can only buy new. .
