Test Method

Request

1

Appearance

By sight:30CM vertically

Case appearance should be smooth w/o nick, burr and other mechanical damage. Exposed metallic part should not be

Oxidized. Case should not be distorted.

2

Insulation Resistance

Test the external packing of battery and insulation between poles using insulation-meter

More than 10MΩ

3

Internal Resistance

AC testing method. In half capacity condition, using AC 1kHz testing method to measure the internal resistance figure between poles in battery connector.

4

Discharging

1) Use nominal capacity charging method full charge the battery.

2) 1C constant current discharge to 8.0V

Discharging time≥90min

5

High temperature Resistant Capability

Put full-charged battery in 55℃±2℃ thermostat for 2h,then use1C discharge to 8.0V

    1)After test, 1C capacity should be ≥35min,internal resistance should be no more than 120% of internal resistance before test.

2) Case appearance should not be distorted and crack.

6

Low temperature Resistant Capability

1) Use nominal capacity charging method full charge the battery.

2). Put full-charged battery in -25℃ ± 2℃ chest freezer for 24h,then use 0.2C discharge to 8.0V

1) After test, 1C capacity should be no less than 70% of it before test,internal resistance should be no more than 150% of internal resistance before test.

2) Case appearance should not be distorted and crack.

7

Cycle Life

After 300 cycles of complete charge and discharge at 1C current, and record the capacity

Battery should not explode smoke, burn or burst. 1C charge and discharge cycle life should more than 300 times

9

Fall Proof Capability

Hang the battery in one meter high in the air. Let the cells fall down by six sides

(Anode and Cathode side,crosswise sides)1 time each,all together 6 times.

1. Battery should not be leak, smoke and burst.

2) After test, 1C capacity should be no less than 95% of it before test. Internal resistance discrepancy should be no more than 3mΩ.

10

Capacity Retention

1) In environmental temperature 20℃± 5℃ condition, Use nominal capacity charging method full charge the battery

2) Lay the battery opened circuit 28D, then use 0.2C discharge it to cut off voltage

0.2C discharging time should no less than 3.20H.

11

Constant Temperature and Humidity Proof Capability

Lay the battery in temperature 40±2℃ and humidity 90% ~ 95% environmental chambers for 48h. Then lay the battery in environmental temperature 20±5℃condition for 2h. Later discharge it in 1C and record the capacity.

1) Battery appearance should not be obvious nick, leak, smoke and burst.

2) 1C discharging capacity should no less than 93min. Internal resistance discrepancy should be no more than 3mΩ.

Test Method

Request

Overcharge Test

Apply 2 times than rated battery voltage and a 2C charge current on the battery for 8hs.

Battery could not be burst, burn, leak and smoke

Over discharge Test

Discharge the battery at 1C to cut off voltage,then discharge with loading 30Ω for 24hs.

Battery could not be burst, burn, leak and smoke

Pack Short-circuit Protection

1. The battery is charged to rated capacity.
2. The battery is to be short circuited by connecting the positive and negative terminals of the battery with thermocouple having a maximum resistance load of 0.3Ω

Battery could not be burst, burn, leak and smoke After charging.
