button battery cr2032

　　How manufacturers test button battery cr2032 packs.

　　The main testing contents of the manufacturer include: capacity detection, load detection, charge and discharge detection, short circuit fault detection, internal resistance detection, working voltage detection, resistor detection, current maintenance detection, set detection, etc.

　　1. Divided volume experiment: The divided volume experiment is used separately, and 1C is used for standard experiments, general experiments and rapid experiments. The activity of button battery cr2032 pack is mainly to better define the capacity and characteristics of the battery pack.

　　2. Charge and discharge inspection: The purpose of battery charge and discharge inspection is to determine whether the charging circuit of the button battery cr2032 package is normal. There are certain regulations on the detection of battery charging working voltage and current.

　　3. Short circuit test: The short circuit test is mainly used to determine whether the overcurrent protection function of the button battery cr2032 pack is normal. Generally speaking, the test standard is to use a fully intelligent detector. When testing, special attention should be paid to the short-circuit fault time should be less than 3 seconds. The multimeter current range or working voltage range cannot be used for short-circuit fault detection.

　　4. Internal resistance test: The internal resistance test is an indicator value for judging the power consumption of the button battery cr2032 pack itself. When the internal resistance is too large, it will affect charging and discharging, or even make it impossible to charge and discharge.

　　5. Overcurrent protection experiment: When the button battery cr2032 pack is fully charged, use a variable resistor to adjust the charge and discharge current so that the current slowly expands. When the charge and discharge current exceeds a certain operating voltage value, the charge and discharge control circuit current is cut off and the current is zero. The current amount before the record is cut off is the over-current protection current amount.
