The battery capacity shall be more than 95%. VMH9011 2 -
The battery shall be discharged at the constant current of 2000mA to 10.0V end voltage within 1 hour after fully charged. The battery capacity shall be more than 79%. The battery is discharged at a constant current of 700mA to 10.0V. Then the battery is charged at a constant current of 400mA for 16 hours. Within 1 hour, the battery shall be discharged at the constant current of 700mA to 10.0V end voltage, the battery capacity shall be more than 50%. 5.4 Self Discharge The battery is charged at constant current of 2000mA for 95minutes, the battery is stored for 28 days at 20, then the battery is discharged at constant current of 2000mA to 10.0V and the battery capacity shall not be less than 55%. The battery is charged at constant current of 2000mA for 95minutes, the battery is stored for 7 days at 40, then the battery is discharged at constant current of 2000mA to 10.0V and the battery capacity shall not be less than 55%. 5.5 Over Discharge Capacity of fully charged battery unit, when discharged with 20 load for 8 hours. shall not cause damage, leakage, salting or degradation in performance characteristics as specified herein. 5.6 Temperature Characteristics The battery is charged at constant current of 2000mA for 95minutes at 40 within 1 hour, the battery is discharged at constant current of 2000mA to 10.0V at 20 and the battery capacity not be less than 67.5%. The battery is charged at constant current of 2000mA for 95minutes at 20 within 1 hour, the battery is discharged at constant current of 2000mA to 10.0V at 0 and the battery capacity not be less than 47.5%. 5.7Safety The battery shall not rupture when charged at 2000mA for 5 hours. However it is acceptable for the battery to sustain leakage of battery fluid and show a change in appearance. The battery shall not rupture when reverse charged at 2000mA for 5 hours, However it is acceptable for the battery to sustain leakage of battery fluid and show a change in appearance. VMH9011 3 -
6. Mechanical Test 6.1 Vibration Test The battery is vibrated in triaxial direction with 4 mm amplitude of frequency 30 Hz (1 Hz per minute) for 1 minute in triaxial direction. The battery is observed to be normal. 6.2 Dropping Test The battery is dropped from a vertical height of 0.5m onto a flat, firm, non-yielding surface. The same battery is dropped in the same manner seven times. The battery is then observed and appears to be normal. 7. SUPPLY The battery should be shipped at charged state. 8. Safety Devices and Abuse Requirement Circuitry protection as described below has been presented inside the battery pack, to insure safety in case of misuse. Over Temperature Protection When battery internal temperature exceeds 75 the thermal interrupter shall trip creating an open circuit that prevents further charging or discharging of the battery. The thermal interrupter will automatically reset when the internal temperature drops below 55. 9. SAFETY PRECAUTIONS AND HANDLING If inappropriate handling of the battery, it may cause the equipment malfunction from affecting the battery. Be sure that the battery pack is handled properly. The battery shall be charged before the first time application by a specified charger. Always keep the battery in a cool and dry place. Be sure to use a charger specified by manufacturer. The battery pack includes flammable organic solvents. If inappropriate handling occurs it is possible that the battery may rupture, leakage, ignite, or overheat, causing irreparable damage. Do not disassemble or modify the battery pack. The battery pack is equipped with built in safety protection features. VMH9011 4 -
Do not externally short circuit the battery packs. Specification Ver. A Do not use or leave battery nearby fire, stove or heated place (more than 80 ). It could melt the resin separator causing it to overheat. If submerged in water, the safety circuitry may be damaged to the point where the safety devices will not operate properly. Possible overheating, ignition and bursting may occur. Do not directly solder on the battery pack. Heat can melt down its insulation and damage safety circuit. Do not use extreme pressure or another medium for potential deformation of the battery pack. An external opposite connection of the battery pack terminals will short-circuit the battery, resulting in the pack overheating, ignition and damage. Do not use the battery pack for using other than those specified by manufacturer. Otherwise, the battery performance may be diminished, its service life may be shortened and it will void the performance guarantee. Do not charge, overcharge, or inverse charge at a higher current than specified. Charging the battery pack using chargers not specified or modified may cause the battery pack to overheat, ignite or explode. If any abnormality or problem of the battery exists, discontinue to use. 10. RECOMMENDED DISPOSAL METHOD The battery contains hazardous waste materials therefore should be disposal by recognized recycle organization. Contact your local agencies to ensure appropriate disposal performed by permitted contractor. Operated by Date July 16, 2002 Checked by Date Approved by Date VMH9011 5 -
