FAQ
Battery and Analysis
What are the main causes of rechargeable battery swelling?
2) The battery has no protection function and the cell expands;
3) The charger has poor performance and excessive charging current causes the battery to swell;
4) The battery is continuously overcharged by high rate and large current;
5) The battery is forced to over-discharge;
6) Issues with the design of the battery itself.
Battery Performance and Testing
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.
