1. The methods of testing

A: Short-circuit electric current: Use ten thousand use the watch test, each time not over 0.5 second, avoid a repeated test, if need to be test again, time partition should be above in the half an hour.

B: Turn on electricity capacity: At 20~25 temperature of the s and 50 ± 10% degree of humid of the load electric current 1 mA under condition, terminate electric voltage for under the circumstance with 2.0 Vs turn on electricity time continuously the capacity measure 12 mAh.

C: The heat test: Deposit under 100 heat for 240 hours, didn't leak a liquid.

D: Lead to turn on electricity to bear to leak a liquid test: Turn on electricity continuously for 5 hours after the battery terminate electric voltage attain a 2.0 V, didn't leak a liquid.

2. Caution

2.1 Install and use the cells right, avoid short circuit and shun reversing anode and cathode.

2.2 Check the cell polarity and the equipment including its conjunction before installing, ensuring the cleanness and conductibility, the equipment should not cause short circuit.

2.3 Do not mix the new cells with the old ones, and not mix the different volume, brand, grade, type cells lest affecting characteristics and the possibility of leaking.

2.4 The cells should not be heated and collided after being used lest explosion, damage and liquid-leaking.

2.5 To avoid danger, dont put the cells into the fire disassemble the cells.

2.6 Taking care of the micro-cells well lest the infants swallow.

2.7 Pay attention to the storage expiry of the cells.
