Honda Fit/Jazz - Battery Test
Battery Test
| A battery can explode if you do not follow the proper procedure, causing serious injury to anyone nearby. Follow all procedures carefully and keep sparks and open flames away from the battery. |
NOTE:
- To get accurate results, the temperature of the electrolyte must be between 21 and 38°C (70 and 100 °F) before testing.
- The PCM memory must be reset after reconnecting the battery.
| Test Equipment Required: |
- Battery Tester with:
Voltmeter with 0-18 V scale, ammeter with 0-100 A and 0-500 A scales, and a carbon pile with 0-300 W - 12 V Battery Charger:
Fast charge capability of 50 A and slow charge capability of 5 A
- Watch the battery voltage during the entire 3 minutes; the highest reading should stay below 15.5 V.
- If the reading stays below 15.5 V, the battery is OK; clean its terminals and case, and reinstall it.
- If the reading exceeds 15.5 V any time during the 3 minutes of fast charge, the battery is not good; replace it.
- If the reading stays below 15.5 V, the battery is OK; clean its terminals and case, and reinstall it.
- If the reading drops below 6.5 V, slow-charge the battery by connecting a battery, and charge at 5 amps for no more than 24 hours (or until the indicator shows full charge, or the specific gravity of the electrolyte is at least 1.270).
Then test load capacity again. - If the voltage stays above 9.6 V, the battery is OK; clean its terminals and case, and reinstall it.
- If the voltage still drops below 6.5 V, the battery is not good; replace it.
- If the voltage stays above 9.6 V, the battery is OK; clean its terminals and case, and reinstall it.
