What This Guide Helps With
Troubleshooting battery charging or reduced runtime caused by AC power, connection, battery condition, charging state, workload, or service-level problems.
Step-by-Step Troubleshooting
1. Protect the Patient and Maintain Clinical Coverage
Do not depend on an unreliable battery for an examination where unexpected shutdown could interrupt clinically necessary imaging or data handling. Connect the system to verified AC power or move the examination to another verified system. Expected outcome: Clinical imaging does not depend on uncertain battery operation.
2. Confirm the Reported Battery Condition
Determine whether the battery does not indicate charging, charges incompletely, discharges unusually quickly, or cannot maintain the system during expected battery-supported operation. Record the displayed battery status and when the behavior occurs. Expected outcome: The complaint is identified as a charging, capacity, indication, or runtime problem.
3. Verify AC Power Is Actually Available
Confirm that the system is connected to a verified working receptacle and that the external power cord and accessible connections are secure and undamaged. A battery cannot charge normally if facility AC is absent or intermittent. Expected outcome: Reliable AC power is confirmed. If restoring AC power restores normal charging, continue through verification and stop troubleshooting when normal operation is confirmed.
4. Observe the Battery and Charging Indications
With the system connected to verified AC power, observe the normal battery or charging indications available on the system. Record any warning or abnormal indication exactly as shown. Do not infer battery failure solely from runtime complaints. Expected outcome: The system recognizes the available power source and displays an appropriate charging or battery state.
5. Allow Normal Charging Opportunity
If the system has been stored, transported, or heavily used on battery, allow it to remain connected to AC power under normal approved conditions. Avoid making conclusions from a battery that has not had a reasonable opportunity to charge. Expected outcome: Battery state improves while connected to AC power and subsequently supports normal operation.
6. Check for External Conditions Affecting Runtime
Determine whether the complaint occurred during unusually long mobile use, repeated startups, extended operation away from AC, or after prolonged storage. Inspect accessible battery-related areas for obvious swelling, leakage, heat, or damage without opening the battery or internal compartments beyond authorized access. Expected outcome: No unsafe physical battery condition is present, and usage conditions are understood.
7. Compare Behavior on AC and Battery Operation
When safe and appropriate, verify stable operation on AC and then observe the system during approved battery-supported operation. Do not conduct extended discharge testing on a device needed for clinical care. Expected outcome: The system remains stable and the battery status behaves normally. If charging and runtime return to normal, troubleshooting can stop after final verification.
8. Perform Final Functional Verification
Verify normal startup, charging indication, stable operation, and any applicable battery-related checks required by facility policy or Canon documentation. Confirm that no battery warning persists. Expected outcome: Battery-supported operation and charging are acceptable for return to clinical service.
9. Escalate Persistent Battery Problems
If verified AC power is available but charging remains abnormal, runtime remains significantly degraded, or the battery shows physical damage or abnormal heat, remove the system from battery-dependent service. Do not attempt cell-level repair or internal charging-circuit troubleshooting. Expected outcome: A suspected battery, charging, power-management, or internal service-level problem is safely referred for repair.
If the Problem Persists
Common external AC power, connection, charging opportunity, and usage-related causes have been ruled out. The remaining issue may involve battery deterioration, charging electronics, power management, battery monitoring, or another internal service-level condition.
Remove the system from service when reliable battery operation is required, label it Out of Service, and send it for repair or bench evaluation. Use approved Canon documentation and appropriate test equipment. Battery replacement or internal repair should be performed only by qualified personnel.
Complete applicable functional and electrical safety testing before return to service. Knowing when to stop after external checks is proper troubleshooting.
Clinical Use Tip
Do not begin a mobile echocardiography examination relying on a battery whose charging condition or runtime is uncertain.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"Clinical staff reported that the Aplio i900 CV battery was not charging while the system was parked between examinations."
Cause
What was observed during troubleshooting.
Example:
"Clinical Engineering found that the system was connected to a receptacle that was not supplying AC power."
Resolution
What action was taken.
Example:
"Clinical Engineering connected the system to a verified powered receptacle, confirmed normal charging indication and stable operation, and returned the unit to service."
Helpful Details to Include (If Known)
- Battery indication at arrival
- Charging indication on verified AC
- AC receptacle test result
- Power cord and connection condition
- Approximate circumstances of reported short runtime
- Whether the system had recently been stored or transported
- Abnormal heat, swelling, leakage, or damage
- Results on AC and battery operation
- Final battery status
- Final device status
Final Thought
Protect continuity of imaging, verify AC availability and charging conditions before condemning the battery, test the corrected condition, escalate unsafe or persistent battery problems, and document the verified findings clearly.
That is successful troubleshooting.
