What This Guide Helps With
Identifies causes of battery not charging or short runtime, including battery condition, charger function, connection, and load issues before assuming internal failure.
Step-by-Step Troubleshooting
1. Ensure Patient Safety
- Confirm the table is not in use with a patient. If it is, safely transfer the patient to another table before troubleshooting.
2. Check Power Source
- Verify the wall outlet is live using a known-good device.
- Ensure any extension cords or power strips are functional.
- Outcome: Table should detect incoming AC power.
3. Inspect Battery Connections
- Turn off the table and disconnect power.
- Remove the battery and check terminals for corrosion, debris, or loose connections.
- Re-seat the battery securely.
- Outcome: Proper contact ensures charging can occur.
4. Verify Charger Function
- Confirm charger is correctly connected to the table or battery.
- Check for indicator lights on the charger showing it is actively charging.
- Swap with a known-good charger if available.
- Outcome: Charger is confirmed operational or replaced.
5. Check Battery Status and Runtime
- Observe battery level indicators on the table or hand control.
- If the table powers on but runtime is short, the battery may be degraded.
- Outcome: Determine if battery retains sufficient charge for normal use.
6. Review Load and Usage Conditions
- Ensure table is not under excessive load or using high-energy movements continuously, which can shorten runtime.
- Outcome: Confirm short runtime is not caused by operational overload.
If the Problem Persists
External checks are complete; the battery may be faulty or the internal charging system may be compromised.
- Remove the table from service.
- Label “Out of Service.”
- Send for repair or bench evaluation.
- Stopping at this point avoids unsafe troubleshooting and preserves patient safety.
Clinical Use Tip
Never attempt to operate the table on battery power with a patient until the battery is verified to hold a full charge. Always move the patient to a table with confirmed power for safety.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"Table battery not charging and provides only short runtime."
Cause
What was observed during troubleshooting.
Example:
"Battery terminals were corroded, and battery capacity is below specification."
Resolution
What action was taken.
Example:
"Cleaned terminals, tested charger, battery replaced, and table verified to hold full charge."
Helpful Details to Include (If Known)
- Outlet tested
- Charger swapped
- Battery level indicators
- Table load conditions
- Final table status (Ready/Out of Service)
Final Thought
Battery issues are common in mobile surgical tables. A logical approach—checking power, connections, charger, and battery health—ensures patient safety and avoids unnecessary internal repairs. Document all findings for proper work order tracking.
That is successful troubleshooting.
