| Item | Test Method | Check Point |
|---|---|---|
| 1. Shock test (Drop test) | A fully charged battery is allowed to drop in the upright position from the height of 20cm onto a hard board having a thickness of 10mm or more. Test is repeated three times. | The battery should be free from noticeable breakage or leaks; and its terminal voltage should be held higher than the nominal voltage. |
| 2. Vibration test | A vibration frequency 1000 times/minute and amplitude 4mm is applied to the X-,Y- and Z- axis directions of a fully charged battery for 60 minutes respectively. | No battery part should be broken; the battery should be free from leaks; and its terminal voltage should be held higher than the nominal voltage. |
| 3. Oven test | A fully charged battery is left standing in an atmosphere of 70°C for 10 hours. | The battery case should be not be deformed; the battery should be free from leaks. |
| 4. Cold proof test | A fully charged battery is connected to a resistor equivalent to 60 hour rate discharge and left for 4 days then the battery is left standing in an atmosphere of -30°C for 24 hours. | No crack should develop in the battery case; the battery should be free from leaks. |
| 5. Heat cycle test | A fully charged battery is exposed to 10 cycles of 2 hours at -40°C and 2 hours at 65°C. | No crack should develop in the battery case; the battery should be free from leaks. |
| 5. Heat cycle test | A fully charged battery is exposed to 10 cycles of 2 hours at -40°C and 2 hours at 65°C. | No crack should develop in the battery case; the battery should be free from leaks. |
| 6. Short circuit test | A fully charged battery connected with a small resistor of 10 ohms or less is allowed to discharge. | The battery must not burn or burst. |
| 7. Large current discharge test | A fully charged battery is allowed to discharge at 3CA to 4.8V/6V battery level. (This test is not applicable to batteries having built-in thermostat.) | The battery must not burn nor burst, and it should be free from battery case deformation, leaks, and any irregularity in the internal connections. |
| 8. Vent valve test | A fully charged battery is submerged in liquid paraffin in a container, then overcharged at 0.4 CA. | Release of gas from the vent should be observed. |
| Overcharge test | A fully charged battery is overcharged at 0.1CA for 48 hours, left standing for one hour, and allowed to discharge at 0.05CA to 5.25V/6V battery level. | No irregularity should be noticed in the battery appearance; the battery should retain 95% or more of the initial capacity. |
