What This Guide Helps With
Troubleshooting failed charging, low battery endurance, rapid discharge, inconsistent charge indication, or suspected battery and external power problems.
Step-by-Step Troubleshooting
Ensure Patient Safety First
Do not troubleshoot an unresolved battery or power problem while the bladder scanner is being relied upon for active clinical assessment.
Move the affected scanner away from patient use and provide clinical staff with another verified bladder scanner when needed.
Expected: Patient care is not dependent on equipment with uncertain battery availability.
Why it matters: An unexpected shutdown can interrupt scanning and create uncertainty about whether the device is ready for continued clinical use.
If removing the affected scanner resolves the immediate clinical concern, continue troubleshooting only in a controlled Clinical Engineering setting.
Confirm the Exact Reported Failure
Determine what “battery not charging” or “short runtime” means operationally.
Check whether the device:
- Shows no charging indication
- Charges only intermittently
- Appears fully charged but shuts down quickly
- Loses charge while powered off
- Operates from external power but not from battery
- Fails only when disconnected from the charger
- Has significantly shorter runtime than comparable units
- Shuts down when moved or when the power cable is disturbed
Expected: The complaint is converted into a reproducible symptom.
Why it matters: Charging failure, poor battery capacity, loose power connection, and inaccurate charge indication are different failure paths.
Inspect the Device and Power Accessories Externally
With the scanner removed from patient use, inspect:
- AC power cord
- External power supply or adapter
- Low-voltage charging lead
- Device power/charging receptacle
- Cable strain-relief areas
- Connector pins and contact surfaces
- Battery compartment area, where externally accessible
- Housing for evidence of impact or liquid intrusion
Look for:
- Loose connections
- Bent or damaged contacts
- Frayed wiring
- Cracked insulation
- Contamination
- Corrosion
- Unusual heat
- Swelling
- Burn odor
Expected: No visible condition explains unreliable charging or creates a safety concern.
If damage, battery swelling, overheating, or burning odor is found, stop troubleshooting, remove the device from service, and escalate for repair.
Verify the AC Source
Connect the charger to a known-good AC receptacle.
When appropriate, verify the receptacle using approved Clinical Engineering test practices or confirm operation with known-good equipment.
Avoid assuming the scanner is defective based only on the originally reported outlet.
Expected: Reliable AC power is available to the charging system.
If the device begins charging normally on a verified outlet, the original power source or facility connection was the likely cause. Document the finding and stop.
Reseat the Complete Charging Path
Disconnect and firmly reconnect:
- AC cord to the power source
- AC cord to the external power supply, when detachable
- Power supply output lead to the scanner
- Any accessible charging connection associated with the mounting arrangement
Observe whether the charging indication changes when the connection is reseated.
Expected: Charging remains stable without requiring pressure, cable positioning, or repeated manipulation.
Why it matters: A partially seated low-voltage charging connector can mimic a failed battery. A field report for this model family specifically describes apparent “battery not holding a charge” complaints associated with the charging cable not remaining connected, so Clinical Engineering should rule out the external charging path early.
If reseating restores reliable charging, document the loose or incomplete connection and stop after verifying stable operation.
Check for an Intermittent Cable or Connector Condition
While observing the charging indication, gently check the external cable near:
- Power supply output
- Strain relief
- Device charging plug
- Scanner receptacle
Do not force, sharply bend, or stress the connector.
Expected: Charging status remains stable during normal cable positioning.
If charging repeatedly drops out with normal movement, substitute an approved known-good power accessory when available.
If the failure follows the cable or adapter, replace the defective accessory and stop after verification.
Compare With a Known-Good Approved Power Supply or Charging Accessory
When an identical approved accessory is available, substitute the known-good:
- AC cord
- External power supply
- Charging lead, as applicable to the configuration
Change one component at a time.
Expected: The substitution identifies whether the failure follows an external power accessory.
If the scanner charges normally with a known-good approved accessory, remove the failed accessory from service, replace it, verify charging, and stop.
Do not substitute an unapproved adapter based only on connector fit.
Observe Charging Behavior Over a Controlled Interval
Connect the scanner to verified external power and record:
- Initial battery indication
- Charging indication
- Time charging begins
- Whether the indication progresses
- Whether charging stops unexpectedly
- Any warning or abnormal message
- Unusual heat from the device, battery area, or power supply
Expected: The device maintains a stable charging state and battery indication progresses appropriately.
If no charging response occurs despite verified AC power and known-good external accessories, continue to the next step.
Perform a Controlled Full-Charge and Runtime Evaluation
For a short-runtime complaint, allow the device to charge fully according to the facility’s approved procedure and manufacturer guidance.
Then disconnect external power and operate the scanner under a consistent, controlled bench-use condition.
Record:
- Starting battery indication
- Start time
- Approximate workload
- Time to low-battery indication
- Time to shutdown, if safely evaluated
- Any abrupt percentage drop or unexpected shutdown
Expected: Runtime is reasonably stable and appropriate for the condition and age of the battery.
Why it matters: A battery may accept a charge indication but have insufficient usable capacity.
If runtime is clearly poor compared with a known-good equivalent unit under similar conditions, suspect battery degradation.
Inspect and Reseat the Battery Only When Externally Accessible and Authorized
If the model configuration provides an externally serviceable battery and facility procedures permit it:
- Power the scanner off
- Disconnect external power
- Inspect the battery and accessible contacts
- Check for contamination, damage, swelling, or abnormal heat
- Reseat the battery securely
Do not open the battery pack or perform internal cell-level work.
Expected: The battery is physically secure and recognized consistently.
If reseating restores normal charging and runtime, complete verification and stop.
Compare With a Known-Good Compatible Battery
When available and permitted by Clinical Engineering procedures, install a known-good compatible battery intended for the BioCon 700 / 750 family.
Medline lists a replacement battery accessory for both BioCon 700 and 750 bladder scanners.
Expected: The substitution separates a degraded battery from a scanner-side charging problem.
If the device charges and operates normally with the known-good battery:
- Remove the failed battery from service
- Replace it with the correct compatible battery
- Verify charging
- Verify acceptable runtime
- Complete final functional checks
Then stop.
Determine Whether the Failure Stays With the Scanner
If the issue persists with:
- Verified AC power
- Secure charging connections
- Known-good approved external power accessories
- A known-good compatible battery
then the fault is more likely within the scanner’s charging, power-management, battery-recognition, or related internal circuitry.
Expected: External and easily replaceable causes have been ruled out.
Do not proceed into board-level troubleshooting unless specifically authorized, trained, and supported by current service documentation.
Perform Final Functional Verification Before Return to Service
After any corrective action:
- Confirm stable startup
- Confirm external power operation
- Confirm charging indication
- Confirm battery recognition
- Confirm operation after external power is disconnected
- Confirm reasonable battery endurance
- Confirm no abnormal heat, smell, or intermittent shutdown
- Perform applicable facility functional checks
Expected: The scanner operates predictably from both the intended external power source and battery before return to clinical use.
If verification fails, remove the device from service and escalate.
If the Problem Persists
If the BioCon 700 / 750 Series still will not charge or has unacceptable runtime after verified AC power, connection checks, approved accessory substitution, controlled charging, battery evaluation, and known-good battery comparison, common external causes have been ruled out.
The device should be:
- Removed from service
- Labeled Out of Service
- Sent for repair or bench evaluation
A persistent failure may involve internal charging, power-management, battery-recognition, connector, or associated electronic circuitry.
Knowing when to stop is proper troubleshooting. Repeatedly replacing batteries without proving the charging path can create repeat failures and unnecessary parts expense.
Clinical Use Tip
Do not troubleshoot an unreliable battery during active patient scanning. Move clinical assessment to another verified bladder scanner first, then evaluate charging and runtime in a controlled Clinical Engineering environment.

What was reported by the clinical staff.
Example:
"Clinical staff reported the BioCon 750 would show a charged battery but shut down shortly after being disconnected from external power."
Cause
What was observed during troubleshooting.
Example:
"Controlled runtime testing confirmed poor battery capacity, and the scanner operated normally with a known-good compatible replacement battery."

Final Thought
Battery complaints should be approached logically: protect patient care, verify AC power, inspect the full charging path, test approved accessories, then evaluate battery capacity. Escalate once external causes are ruled out, and document the complaint, confirmed cause, and verified resolution clearly.
That is successful troubleshooting.
