CR2032 Battery test method
The first is shape detection：
Tool vernier caliper test
The precision of the vernier caliper is greater than 0.02mm, and an insulating material can be attached to the head of the caliper to protect the battery.
Test reference value: CR2032 standard size
| Standard | |
| Diameter | 20.0(-0.2)mm |
| Height | 3.2(-0.2)mm |
The second test method is open circuit voltage test：
The accuracy of the universal meter is not less than 0.25% and the internal resistance is greater than 1MΩ.
When testing with a multimeter, try not to repeat the test. The time of each test should not exceed 0.5 seconds. If necessary, please wait half an hour before the second test.

Led lamp test method:
The pulse discharge was tested using a red LED, which flashed every 1.5 seconds until the termination voltage was reached.
(At a temperature of 20~25℃ and a humidity of 65±20%)
reference value
| Standard |
| ≥600000 times |
