Data Sheet

SAMSUNG SDI Confidential Proprietary

Spec. No. INR18650-29E Version No. 1.0

7.10 Status of the cell as of ex-factory

The cell should be shipped in 3.44V ~ 3.54V Charging voltage range.

8. Mechanical Characteristics

8.1 Drop Test

Test method: Each fully charged cell or battery is dropped three times from a height of

1.0 m onto a concrete floor. The cells or batteries are dropped so as to

obtain impacts in random orientations. After the test, the sample shall be

put on rest for a minimum of one hour and then a visual inspection shall

be performed.

Criteria: No fire, no explosion

(Test shall be performed with the following criteria IEC 62133)

8.2 Vibration Test

Test method: As to the UN transportation regulation(UN38.3), for each axis (X and Y

axis with cylindrical cells) 7Hz→200Hz→7Hz for 15min,

repetition 12 times totally 3hours, the acceleration 1g during 7 to 18Hz

and 8g (amplitude 1.6mm) up to 200Hz.

Criteria: No leakage, with less than 10mV of OCV drop

9. Safety

9.1 Overcharge test

Test method: To charge the standard charged cell with 12V and 3C(8,250mA) at 23°C

for 7 hours

Criteria: No fire, and no explosion.

Overcharge test shall be performed with the UL1642 standard

9.2 External short-circuit test

Test method: Fully rated charged cell is to be short-circuited by connecting the positive

and negative terminals of the battery with a circuit load having a

resistance load of 80 ±20 mΩ. The battery is to discharge until a fire or

explosion is obtained, or until it has reached a completely discharged

state of less than 0.2 V and the battery case temperature has returned to

±10°C of ambient temperature. The return to near ambient of the battery

(cell) casing in an indication of ultimate results.

Tests are to be conducted at 20 ±5°C and at 55 ±5°C.

Criteria: No fire, and no explosion.

External short-circuit test shall be performed with the UL1642 standard
