TEST METHODS
STANDARED
1
Dimensions
Using vernier caliper (accuracy≥0.02) while
avoiding short-circuit
Diameter
20.0 (-0.20) mm
Height
2.5(-0.20) mm
2
Off-load
voltage
Using multimeter (accuracy≥0.25%) internal
resistance≥1MΩ
≥3.20v
3
Instantaneous
short-circuit
current
Time of short-circuit should be less than 0.5
second and avoid repeated test within half
an hour
≥250 mA
4
Appearance
Eyeballing
Bright, clean, no rust, no
leakage, And no flaw
5
Capacity
Continuously discharge for 8 hours with
load 7.5kΩ, temperature at 20~25℃,
humidity at 65 ± 20% till 2.0v end-voltage
(for fresh battery only: within 3 months )
≥375h
6
Vibration test
Put battery on the platform of the vibrations
machine, start the machine and adjust the
frequency form 10 times per minute to 15
times per minute. keep it running for an hour
Characteristics keep stability
7
Leakage at
high
temperature
Stored under temperature (45℃) for 30
days
No leakage allowed
8
Over
discharge
Test
After 2.0v end-voltage, continuously
discharged for 5 hours
No leakage allowed
