Class II — the FDA judged the product may cause temporary or medically reversible harm, with a remote chance of serious harm.
This is the FDA's risk judgment for this recall. It describes the potential of the product as a category — it does not establish that any specific unit harmed anyone. Most recalls are Class II or III.
Brand Name: HiResolution" Bionic Ear System Product Name: M Zn-Air Battery Pak Model/Catalog Number: CI-5501-110; CI-5501-120; CI-5501-130; CI-5501-140; CI-5501-150; CI-5501-190; CI-5501-240; CI-5501-250; CI-5501-260; CI-5501-270; CI-5501-280 Software Version: Not Applicable Product Description: The M Zn-Air Battery Pak is a disposable power source for the Naida" CI M and Sky CI" M Sound Processors. The type of disposable battery to be used with the M Zn-Air Battery Pak is a 675 power implant battery (P675). Regular 675 hearing instrument batteries will not be powerful enough for a cochlear implant. The suggested manufacturer and battery is PowerOne P675 Implant Plus battery. The M Zn-Air Battery Pak is available with non-tamperproof and tamperproof cartridges. Component: Not Applicable
Why it was recalled
The non-tamperproof battery door supplied with the sound processor fails to conform to IEC 60601-1-11:2015 by not requiring the use of a tool to replace the button/coin cell battery.
Is your unit affected?
The recall covers only the specific lots or serial numbers the FDA listed. Enter the lot or serial number from your product's label and we'll check it against that list.
A match means your unit may be covered — stop and call your pharmacist before doing anything. No match suggests it isn't covered, but confirm anyway: code formats vary and lists can be incomplete. Your unit not being listed does not guarantee it is safe, and being listed does not mean you have been harmed.

What this is — and is not
A recall is a recorded FDA enforcement action — the FDA logged that a firm is removing or correcting a product. It does not establish that any specific unit harmed anyone, and causation is not established by a recall. The class above is the FDA's risk judgment for the product category, not a finding about your unit. This page informs and compares; it is not medical advice and never tells you to start or stop a drug or device.
