1. Battery consumption: The battery voltage is not degraded and the capacity is lowered. The pen is used to measure the voltage gauge, if the voltage of the 18650 battery is below 2.
7V or no voltage. This battery or battery pack is damaged. Normal voltage 3.
0V ~ 4.2V (typically 3.0V battery voltage is closed, 4.
2V battery voltage is full of saturation, and there are 4.35V). 2, the battery voltage is below 2.
7V, can charge the battery 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 filled voltage. If the full charge voltage is 4.
2V, the battery is normal and should be that the last use consumption is too much, the battery is closed. If the full charge voltage is less than 4.2V, it means that the battery is damaged.
If it is a long battery, it can be determined that this battery life is in, and the capacity is basically exhausted. Should be replaced. Basically, there is no way to fix it.
After all, the lithium-ion battery is life-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 enters "to charge the battery in a short period of time, it is possible to fix it.
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, and you can only purchase new.
4, check the battery capacity, set the multimeter as measuring the amount of current passed through, placing the two metal rods on the battery positive and negative electrode metal end. 5, check the multimeter display. The most inert 18650 lithium ion battery pack battery's milliamps MAH is consistent with the label, declare that the battery is in good usage.
Measure the voltage of the voltage during use, when the discharge voltage drops, if the reading exceeds 5%, lower than the capacity on the label, please charge your battery until the end of the bore, if the battery detection is still low, if the actual reading is still low For the capacity of the label, please replace the battery in time because the battery is not powered.
