18650 lithium-ion battery pack consumption how to test

1. Battery consumption: The battery voltage is not degraded and the capacity is lowered. Direct voltage gauge measurement, if the voltage of 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 to the charger prompt, and then watch the voltage. If the full charge voltage is 4.

2V, it indicates that the battery is normal, it should be too much power consumption, the battery is closed. If the full charge voltage is less than 4.2V, it indicates that the battery is damaged.

If you use 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, the battery has no voltage. This time there is two cases.

One is that the battery is good, and the 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 case where the milliamps MAH fully charged 18650 lithium ion battery pack battery is consistent with the label indicates that the battery is in good usage.

When the measurement is used during use, when the discharge voltage drops, if the reading exceeds 5%, if the capacity below the label is lower than the label, please charge your battery until it is full, and the battery detection is again, if the reality is still low. For the capacity of the label, please replace the battery in time because the battery is not powered.
