CHASSIS ELECTRICAL - Battery 54A-5 Caution 1. The battery plugs should be removed during charging. 2. The battery electrolyte level may rise and overflow from the battery during charging. 3. Explosions may occur if the battery is brought close to naked flames during charging. 4. Be careful to avoid tasks that might produce sparks or other danger while the battery is charging. 5. After charging is complete, replace the battery plugs, pour water over the battery to rinse away any sulphuric acid, and let the battery stand to dry. 6. Charge the battery in a well-ventilated location. 7. Do not let the battery electrolyte temperature rise above approximately 45_C (approximately 55_C during rapid charging). BATTERY TESTING PROCEDURE TEST STEP (1) Turn headlamps on for 15 seconds. (2) Turn headlamps off for 2 minutes to allow battery voltage to stabilize. (3) Disconnect cables. OK Read open circuit voltage. OK: Open circuit voltage is more than 12.4 V NG Charge battery at 5 amps. (Refer to LOAD TEST RATE CHART) Retest OK (1) Connect a load tester to the battery. (2) Loadthebattery at therecommended dischargerate (seeLOAD TEST RATE CHART) for 15 seconds. (3) Read voltage after 15 seconds, then remove load. (4) Compare the measured value with the minimum voltage (see LOAD TEST CHART). OK: Higher than minimum voltage NG Replace battery OK Normal ROAD TEST RATE CHART Battery type 44B20L Charging time when fully discharged h [5-amp. rated current charging] 6.8 Load test (Amps) 150 ROAD TEST CHART Temperature _C 21 and above 16 – 20 10 –15 4 – 9 -1 – 3 -7 – -2 -12 – 8 -18 – -13 Minimum voltage V 9.6 9.5 9.4 9.3 9.1 8.9 8.7 8.5 |
