: Indicates the battery is fully charged and ready for operational use.
The Exide CMP 2100 control board runs a continuous diagnostic background loop. If a boundary parameter is exceeded, it halts operation and displays an error code. Below is an engineering matrix detailing standard faults: Fault Display / Symptom Probable Cause Corrective Action Blueprint
The charger automatically stops when the battery is fully charged.

Once the display reads "Full" or the current drops to near zero (usually <0.5A), the battery is fully charged. Unplug the charger from the wall first, then disconnect the clamps (Negative first, then Positive).
| Issue | Possible Cause | Solution | | :--- | :--- | :--- | | | No power from outlet / Blown fuse | Check wall outlet; check internal charger fuse if accessible. | | "Error" or Flashing Light | Reverse Polarity | Clamps are connected backwards (+ to -). Disconnect immediately and correct polarity. | | Charger will not start | Battery voltage too low | Some smart chargers will not engage if voltage is below 4V. Use a "jump start" or manual charger to boost voltage slightly, or use the "Recond" mode if available. | | Battery not reaching 100% | Wrong mode selected / Sulfated battery | Switch to the correct battery type mode. If the battery is old, it may have permanent sulfation and require replacement. |
: Install in a clean, dry room with an ambient temperature between 32°F (0°C) and 104°F (40°C). : Indicates the battery is fully charged and
Monthly Inspection: Check DC cables for fraying or heat damage.
: Indicates a system malfunction, safety timeout, or incompatible battery connection.
Red/Amber alternating lights indicate that the charger is attempting to desulfate or recover a deeply discharged battery. Below is an engineering matrix detailing standard faults:
: Never connect or disconnect the DC charging plug while the charger is actively running. This creates an electrical arc that can ignite hydrogen gas.
: Inspect the battery for correct water levels and damaged cables.
Always turn off or disconnect the AC power supply before connecting or disconnecting the DC plug from the battery. Disconnecting under load causes severe electrical arcing.
