respectively. (Ambient temperature is 20±5)℃

5.3 Humidity

The cells shall not leak during the 14 days when it is submitted to the

see note 3

condition of a temperature of 33±3 ℃ and a relative humidity of

80±5% (salting is allowed).

5.4 Vibration

Cells shall be mechanically and electrically normal after vibration which

has an amplitude of 4mm(0.1575 inches) a frequency of 1000 cycles

per minute, which should be continued in any directions during 60 minutes

5.5 Shock

Cells shall be mechanically and electrically normal after being subjected

to a drop from a height of 450mm (17.716inches) onto an oak board in

a voluntary axis respectively 3 times.

5.6 Short

Cells shall not explode after 1 hour short-circuit test.

5.7 Incorrect polarity charging

Cells shall not explode after 5 hour of incorrect polarity charing at 1 CmA.

6. PRECAUTION

6.1 We recommend you to set the cut-off voltage at 1.0V/cell.

6.2 If it is below 1.0V/cell, cells may have over-discharged or reverse charged.

6.3 Do not detect -△V for first 5 minutes of charging.

6.4 The cells shall be delivered in discharged condition, Before testing or

using, the cells shall be correctly charged in accordance with this specifications.

7. WARNING

7.1 Avoid direct soldering onto cells.

7.2 Observe correct polarity when connecting.

7.3 Do not charge with more than our specified current.

7.4 Use only within the specified working temperature range.

7.5 Do not subject cells or batteries to mechanical shock.

7.6 Do not mix cells of different manufacture,capacity,size or type within a battery.

7.7 Seek medical advice immediately if a cell or battery has been swallowed.

7.8 When disposing of secondary cells or batteries ,keep cells or batteries

of different electro-chemical systems separate from each oter.

7.9 Do not maintain secondary cells and batteries on charge when not in use.

8. DANGER!

8.1 Avoid throwing cells into a fire or attempting to disassemble them. As the

electrolyte inside is strong alkaline and can damage skin and clothes.

8.2 Avoid short circuiting. It may be leakage.
