3.Test method
| No. | Item | Condition |
| 1 | Dimensions | When measure with vernier calipers whose precision is up 0.02mm. to avord short circuit,should paste on one insulation material on one end of the vernier calipers |
| 2 | Open voltage | the precision of multimeters is not lower than 0.25%,intel resistance is bigger than 1MΩ |
| 3 | Instant short-circuit current | When test with multimeters, not surpass 0.5 second each time, avoid duplicating tests, if need once more, the time-gap should above half hour |
| 4 | Appearance | visual |
| 5 | Min time of discharge | Takes 9 batteries stochastically,Lay aside above 8 hours in the temperature of 20±2℃ and under the humidity of 60±15% conditions, with the condition that Resistance is 15 kΩ,end-point voltage is 2.0V. The new battery (Initial stage)should be tested in 60 days after produce. The old battery (Delayed for 12 months) should be tested in 14 days after the storage period. |
| 6 | Over-discharge Characteristics | Take nine battery in the temperature of 20±2℃ and under the humidity of 60±15% conditions, with the condition that Resistance is 15 kΩ,end-point voltage is 1.2V. visual test. |
4.Acceptance rule
Check Criterion: ISO2859-1:1999(GB/T2828.1-2003),
The concrete item see the sheet of the following :
| No. | Check item | IL | AQL |

5.Cautions for Use
5.1 The battery shall be installed with its “+” and “-“ polarity in a correct position, otherwise may cause short-circuit.
5.2 Short-circuiting, heating, disposing of into fire or disassembling of battery is prohibited.
5.3 Battery can not be forced discharged, which leads to excess gassing and may result in bulging, leakage or explosion.
5.4 New batteries and used ones can not be used at the same time. It is recommended to use the same brand when replacing batteries.
5.5 Direct soldering is not allowed, or else it will damage the battery.
5.6 Battery are to be kept away from children. If swallowed, contact a physician at once.
6.Marks and Meanings of the words on battery surface:
1) ‘+’means battery positive pole
2) ‘CR2032’means battery model
3) ‘リチウムバシテリ－’means Lithium Battery
4) ‘3V’ means battery voltage
