Naida CI Q90 Rechargeable Battery Replacement – PowerCel 230

The Naida CI Q90 Battery is a replacement PowerCel 230 rechargeable battery for the Advanced Bionics Naída CI Q90 sound processor. It is the largest cell in the Naída CI PowerCel range, so it is the size Q90 wearers usually pick when they want the longest day between charges. It carries the reference CI-5523, comes in black, and clicks onto the base of your processor in exactly the same way as the battery it replaces.

The Q90 is the newest processor in the Naída CI Q family and the one with built-in wireless connectivity, so its batteries tend to work harder than those on older Q models. If your current Naida CI Q90 battery no longer gets you through the day, has a cracked body, or keeps losing contact, this page explains how to confirm the fit, what to look out for, and how to get the most from the new cell.

Many people search for this part as the “AB Q90 230 battery”, the “Naida Q90 battery” or simply “Powercell 230”. Whichever name you know it by, it is the same large PowerCel size, built to the same connector and dimensions, and checked on a charger before it leaves us.

Will this Naida CI Q90 Battery fit my processor?

The PowerCel family uses one connector across the whole Naída CI Q range, so the battery itself is interchangeable between the Q30, Q70 and Q90. We list it under each processor to make it easier to find alongside the matching charger, ear hook and cable. The table below shows where it fits and where you need a different part.

Why Q90 wearers keep a spare PowerCel 230

The Q90 is still in daily use around the world, but it is no longer the newest Advanced Bionics processor, and a replacement Naida Q90 battery through a clinic can take weeks once a warranty has ended. Users on hearing-loss forums describe paying out of pocket for off-warranty work and say that, given the cost of parts, reliability matters more than anything.

A second charged battery removes most of that stress. You can rotate two cells so neither is drained to empty every day, carry one in a bag for long days out, and still hear if one battery fails unexpectedly. For a processor you rely on from morning to night, a backup is the cheapest insurance you can buy.

One Q90 user on HearingTracker reports getting around 8 hours per charge from a PowerCel 230. That is one person’s experience, not a rating: your own time depends on your program, how much you stream, the age of the cell and the temperature. It does show why a fresh spare ready for the evening is worth having.

Signs your Naida CI Q90 battery needs replacing

Rechargeable cells wear gradually, so the change is easy to miss. These are the signs people describe most often before they replace a Naída CI PowerCel:

• It does not last as long as it used to. Users say their batteries stop lasting as long as stated, and the day ends earlier and earlier.
• The battery body cracks. One Q90 user reports that both of their batteries developed body cracks over time. A cracked case lets in sweat and moisture.
• Sound cuts in and out. If sound drops when you move your head or touch the processor, a loose or corroded battery contact is a common cause.
• Corrosion on the contacts. Green or white marks on the metal pads cause a poor connection between battery and processor.
• It will not charge fully. The charger never reports a full charge, or the battery feels warm and still runs flat quickly.
• No visible damage, but it stopped working. Cells can fail internally even when the outside looks perfect.

If the same symptom shows up with two different batteries, the processor or charger may be the cause. Our troubleshooting table below helps you narrow it down.

How to fit and charge your Naida CI Q90 Battery

1. Unpack the battery and check the contacts are clean and the case is undamaged.
2. Place it in your Naída CI PowerCel charger and give it a full first charge before you use it.
3. Remove the old battery from the base of your Q90 the way your clinic showed you.
4. Line up the new PowerCel 230 with the base of the processor and press gently until it clicks into place. Do not force it; it only fits one way.
5. Start the processor and listen for the usual start-up signal, then check sound through your normal listening check.
6. Return the old battery to the charger only if it still works as a backup; otherwise keep it away from heat and recycle it at a battery collection point.

Charge each new cell fully for the first few cycles and avoid running it completely flat. A battery that is used and recharged regularly tends to behave more predictably than one left in a drawer for months.

Troubleshooting a Naida CI Q90 battery

What you see	Likely cause	What to do
Battery runs flat well before evening	Cell is ageing or heavy wireless use	Charge fully overnight, try a second battery, and compare
Sound cuts out when you turn your head	Loose fit or dirty contacts	Remove the battery, wipe the contacts with a dry cloth, refit until it clicks
Charger does not show a full charge	Contacts on battery or charger are dirty	Clean both sets of contacts and try another charger slot
Visible crack in the battery case	Wear and knocks over time	Stop using the cell and replace it
Green or white marks on contacts	Moisture and sweat causing corrosion	Clean gently; if marks return, replace the battery and dry the processor nightly
Problem stays with every battery	Processor or charger fault	Contact your clinic; a new battery will not fix a processor fault

How to make your Naida CI Q90 Battery last longer

• Keep cells out of hot cars, sunny windowsills and radiators. Heat is the fastest way to shorten a rechargeable battery.
• Wipe the contacts with a soft dry cloth once a week, especially in hot or humid weather.
• Store the processor in a drying unit overnight. Our electric dryer helps limit the moisture that leads to corrosion.
• Rotate two batteries so each one gets a rest and neither is drained to empty every day.
• Carry the spare in a small case, never loose in a pocket with keys or coins.
• Replace a cracked battery straight away rather than taping it.

As a rough guide, many rechargeable processor batteries start to show shorter days after about a year of daily use. If yours is older than that and the day feels short, it is probably time for a fresh cell.

Is a replacement Naida CI Q90 battery safe?

This Naida CI Q90 rechargeable battery is a third-party replacement made to be compatible with the Naída CI Q90. It uses the same connector, size and electrical specification as the PowerCel 230 it replaces. We are not Advanced Bionics and we do not sell parts as the manufacturer’s own; we sell compatible replacements and say so clearly.

Every Naida CI Q90 battery is checked before dispatch: we confirm it fits the processor, takes a charge and holds it. If it arrives defective or is the wrong item, we replace it or refund you. If you have any doubt about your setup, talk to your audiologist, who knows your full implant history.

PowerCel 230, 170 or 110 Mini on a Q90?

The Q90 accepts all three PowerCel sizes. The trade-off is simple: a bigger cell lasts longer but adds a little weight and length behind the ear. A smaller one feels lighter but needs charging sooner.

Size	Character	Good for
PowerCel 230 (this page)	Largest and longest-lasting	Full days, travel, heavy streaming
PowerCel 170	Middle size	Wireless users who want a balance; see our AB Naida Q90 Bluetooth battery
PowerCel 110 Mini	Smallest and lightest	Comfort, sport, short days; see the Naida Q90 PowerCel 110 Mini

A practical setup is one large cell for the working day and one smaller cell for evenings or exercise. Any mix works, because every size charges in the same Naída CI PowerCel charger.

Naida CI Q90 Battery FAQ

How long does the Naida CI Q90 battery last per charge?

It depends on your program, streaming and the age of the cell. One Q90 user reports around 8 hours per charge from a PowerCel 230, but treat that as one person’s experience rather than a promise.

Is this the same as the “AB Q90 230 battery”?

Yes. “AB Q90 230 battery”, “Powercell 230” and PowerCel 230 all describe this large size for the Naída CI Q90.

What part number is it?

This replacement matches the PowerCel 230 reference CI-5523.

Will this Naida CI Q90 battery work with my existing charger?

Yes. It charges in the standard Naída CI PowerCel charger used across the Q series.

Can I use it on a Naída CI Q70 or Q30?

Yes. The PowerCel connector is the same across the Q30, Q70 and Q90. We also list it under those processors so it is easy to find.

Will it fit a Naída CI M90 (Marvel)?

No. Marvel processors use a different battery family. This cell is for the Naída CI Q range only.

My battery case has cracked. Is it still safe to use?

We would stop using it. A crack lets moisture reach the cell and contacts, which can cause poor connection and cut-outs.

Should I buy one Naida CI Q90 battery or two?

Two is easier to live with. You can rotate them, keep one charged as a backup, and still hear if one fails.

Do I need my audiologist to order this?

No prescription is needed for a Naida CI Q90 rechargeable battery. If you are unsure about your processor model, send us a photo and we confirm it.
