There are many types of batteries, button batteries, power batteries, lithium batteries, storage batteries, special-shaped batteries, etc., but despite the different types, any battery must go through a series of quality inspections before leaving the factory, such as the charge and discharge test of button batteries , is to test the charge and discharge performance of the button battery, then, how to do the charge and discharge test of the button battery?
Preparations before the button battery charge and discharge test:
After the button battery is assembled and formed, let it stand for a period of time before performing the charge and discharge test. When charging and discharging, discharge is carried out by means of constant current, and the standard of charging and discharging may be different under different circumstances. We can get the charge and discharge capacity and battery cycle performance of the button battery through different charge and discharge current ratios and constant current charge and discharge tests in different charge and discharge voltage ranges.
Knowing the method is important, but the equipment is more important
We already know the method of button battery charge and discharge test, but it is still a difficult problem to use which method to test. If a multimeter is used, the test results are generally not accurate, and it is not suitable for battery manufacturers or battery research institutions. It is recommended that manufacturers and battery research institutions use more professional battery testing instruments, so that the error obtained is smaller and the test is more accurate.
