How to measure 18650 lithium-ion battery capacity

　　Author ：Iflowpower – Portable Power Station Supplier

The rated voltage is typically 3.7V, with a professional battery buffer cabinet, typically set to 3.6V or 4.

2V, reaching the rated voltage, the capacity recorded in the second step is the capacity of the battery. The arbitration mode is based on 0.2 magnification, such as 1000 mAh capacity.

18650 Paracted Cabinet Measures 3: Battery Capacity Tester, usually 4.2V or 3.6V, step 2: discharge battery, calculate time * constant current current = battery capacity,.

Lithium iron phosphate ions are 3.2V, which can be found to be operated and discharged to calculate the battery capacity by charging and discharging, and discharging the battery capacity to 2.75V.

Step 3: Charge the battery to normal. First charge to 4.20V, charging current charging time = battery capacity (from 2.

7V or 3.6V) or discharge current discharge time = battery capacity (from 4.2V or 3.

6V to 2.7V or 3.0V 18650 Lithium Ion Battery Measures 2: First Step: Powering the battery and then puts 1 hour constant current discharge.

Delicate the full power voltage, if there is no professional battery bundle cabinet.
