| Problem | Cause | Corrective action |
| 1. No output voltage from the charger | AC voltage not supplied | Check installation
Check fuse valve, replace if necessary |
| 2. Battery charger does not operate | AC voltage not supplied | Check installation The AC green LED should light up, if power is supplied |
| Input voltage too low | Check fuses or circuit breakers | |
| The battery charger will not operate below 160/80V | Check the input voltage | |
| 3. The battery charger does not operate, while mains voltage is present | Mains frequency could be too high or too low | Check the input frequency |
| The frequency must be within 35-66 Hz | Check | |
| 4. Batteries not fully charged | Charge current too low | See “charge current too low” |
| Current to load too high | Decrease the battery load | |
| Charge time too short | Replace the battery | |
| Battery temperature too low | Use temperature sensor | |
| Defective battery (short circuit in cell) | Replace the battery | |
| 5. Battery loses charge quickly | Battery capacity reduced because:
|
Replace the battery |
| Charge/discharge several times, this might help, otherwise replace batteries | ||
| 6.Batteries are warm | Defective batteries (short circuit in cell) | Replace batteries |
