Selecting a charger that uses minimum charge-current termination (C/10 or C/x) can also extend battery life by not charging to 100% capacity. For example, ending a charge cycle when the current drops to C/5 is similar to reducing the float voltage to 4.1 V. In both instances, the battery is only charged to approximately 85% of capacity, which

6 FAQs about [How to calculate the termination voltage of lithium battery]

What is a charge termination current limit?

C/10 and C/30 are common charge termination current limits. When the battery is fully charged, the battery should be disconnected from the charger. Leaving the battery connected to the charger will cause the battery to overcharge and will damage the battery. The 18650 is popular cylindrical lithium cell, with a capacity of 2500 mAh.

How to charge a lithium battery?

When charging the lithium battery, a dedicated constant current and constant voltage charger should be used. After constant current charging, the lithium battery voltage reaches 4.2V, then it is switched to the constant voltage charging mode; when the constant voltage charging current is reduced to 100mA, The charging should be stopped.

When should a battery be terminated?

When the current drops below a datasheet value, charging should be terminated. C/10 and C/30 are common charge termination current limits. When the battery is fully charged, the battery should be disconnected from the charger. Leaving the battery connected to the charger will cause the battery to overcharge and will damage the battery.

How many Ma can a lithium battery charge?

The charging current (mA) can be 0.1 to 1.5 times the battery capacity, for example, a 100 Ah lithium battery, and the charging current can be controlled between 10A and 150A. The normal charging current can be selected to be about 0.5 times (0.5C) the battery capacity, and the charging time is about 2-3 hours.

What happens if a lithium cell has a constant current charge?

During the constant current charge, the lithium cell is discharged. The cell will sink as much current as it is given, although providing too much current may be dangerous. Stay at or below the limit specified by the datasheet. A standard charge on a datasheet is typically defined as 0.5 C, where C stands for capacity.
