Capacity data and steps of 18650 polymer battery

1. Fully charge the battery to 4.2V or 3.6V (iron lithium) with a standard charging current of 0.5C (approximate battery capacity × 0.5 u003d standard charging current); charging time (approximate battery capacity u0026 pide; charging current u003d charging time), upper limit voltage Set to 4.2±0.05V or 3.6±0.05V (Iron Lithium). Cut-off charging current is set to 30mah to stop charging. 2. Set aside the device and stop it for a few minutes (3 minutes or 5 minutes) before proceeding to the next step. 3. Discharge the battery to 2.75V or 2.5V (iron lithium) with a standard discharge current of 0.5C (approximate battery capacity × 0.5 u003d standard discharge current); discharge time (approximate battery capacity u0026pide; discharge current u003d discharge time), the lower limit The voltage is set to 2.75V or 2.2V (iron lithium). 4. Set aside the device and stop it for a few minutes (3 minutes or 5 minutes) before proceeding to the next step. 5. Charge the battery to the voltage you want (3.8V or 3.9V) with a standard charging current of 0.5C (approximate battery capacity × 0.5 u003d standard charging current); charging time (approximate battery capacity u0026 pide; charging current u003d charging time) , The upper limit voltage is set to the desired voltage 3.8V or 3.9V, the cut-off charging current is set to 30mah to stop charging. 6. Stop and stop to complete all operation steps and each indicator light of the capacity division equipment lights up at the same time. All the operation steps have been completed above. Now check the discharge capacity, then what is the actual capacity of the lithium battery. If it is a large device with 512 dotted batteries, first return to the main page, and then enter the capacity page, enter the capacity section, and send the lithium battery indicator light to confirm the input capacity section. If it is a sub-capacity device with 8 dots of batteries, you can directly open the data on the computer to view the discharge capacity.
