Using Battery Voltage Method
- Inspect the battery as follows after removing the battery filler caps, checking the water level, and adding water to the appropriate level if needed:
| Step | Inspection | Results | Action |
|---|---|---|---|
| 1 | Measure the battery positive voltage. | 12.4 V or more | Go to Step 3. |
| Less than 12.4 V | Go to the next step. | ||
| 2 | Quick charge for 30 min and recheck voltage. | 12.4 V or more | Go to the next step. |
| Less than 12.4 V | Replace the battery. | ||
| 3 | Using the battery load tester, apply load current (see battery load test current) and record battery voltage after 15 s. Is voltage more than the specification? | Yes | Normal |
| No | Replace the battery. |
Battery load test current
- 48A.h/5HR, 60A.h/20HR: 180 A
- 52A.h/5HR, 65A.h/20HR: 195 A
