What is the standard charge retention test?
After the battery is discharged to 1.0V at 0.2C, it is charged at 0.1C for 16 hours, stored at a temperature of 20℃±5℃ and a humidity of 65%±20% for 28 days, and then discharged to 1.0V at 0.2C. NiMH batteries should last longer than 3 hours.
The national standard stipulates that the standard charge retention test of lithium batteries is: (IEC has no relevant standards) The battery is discharged to 3.0/unit at 0.2C, and then charged to 4.2V at 1C constant current and constant voltage, with a cut-off current of 10mA, at a temperature of 20 ℃±5℃, after 28 days of storage, discharge at 0.2C to 2.75V, calculate the discharge capacity, and compare it with the battery's nominal capacity, it should not be less than 85% of the initial capacity.
What is static resistance? What is dynamic resistance?
