Naida CI Q70 Rechargeable Battery Replacement – PowerCel 230

The Naida CI Q70 Rechargeable Battery is a replacement PowerCel 230 for the Advanced Bionics Naída CI Q70, the middle processor of the Naída CI Q family. It is the large PowerCel size, black, with the reference CI-5523, and it slides onto your Q70 exactly like the cell you are replacing. If your Q70 still works well but its batteries are tired, this is a simple way to keep it going.

A rechargeable battery is the part of a Q70 that wears out first, and a worn cell is the most common reason a perfectly good processor stops lasting the day. We stock compatible PowerCel batteries so you can keep hearing with the processor you already know.

Users often write the name as “Powercell 230” or search for a “Naida Q70 battery”. The part is the same: a large rechargeable cell that gives your Q70 the most time between charges of any PowerCel size. Each Naida CI Q70 rechargeable battery is new, not refurbished.

Will this Naida CI Q70 Rechargeable Battery fit my Q70?

Yes, if your processor is a Naída CI Q70. The whole Q range shares the same PowerCel connection, so the battery also fits a Q30 or Q90, which is handy in households with more than one Q processor. Here is the full picture:

Processor	Fit	Notes

To check your model, look at the processor itself or the box and paperwork from your implant clinic. If the writing has worn away, a clear photo sent to us on WhatsApp is usually enough for us to identify it.

Why Q70 users keep a spare battery

The Naída CI Q70 was released before the Q90 and the newer Marvel generation, and many wearers plan to keep using it for years. Batteries lose capacity with every charge cycle, so a second cell is the simplest way to protect a full day of hearing.

An upgrade can mean a long wait and a large bill, especially once a warranty has ended or insurance will not cover a new processor. For many people, a fresh battery is all the Q70 needs to keep working every day.

That is why we keep compatible Q70 batteries in stock and ship them worldwide. If you depend on a single cell at the moment, now is a sensible time to add a second Naida Q70 battery.

Even people who do move to a newer processor often keep their Q70 as a backup. A charged Naida CI Q70 rechargeable battery in the drawer means that if the new processor goes away for repair, you can switch back to the Q70 the same day instead of waiting without sound.

Signs your Naida CI Q70 rechargeable battery is wearing out

• Shorter days. Q70 users say batteries do not last as long as stated, and an older cell may run flat by mid-afternoon.
• Corrosion at the contacts. A Q70 reviewer reports corrosion that caused poor connection in both the battery and the headpiece cable. You may see green, white or dark marks on the metal pads.
• Intermittent sound. Sound that comes and goes when you move or touch the processor often points to a loose or dirty battery contact.
• Charging trouble. The charger never shows a full charge, or the cell warms up and empties quickly.
• Physical damage. Cracks, swelling or a battery that no longer clicks firmly into place.
• Sudden failure. The battery looks fine but simply stopped working.

It also helps to note when each Naida CI Q70 rechargeable battery was bought. When cells of different ages behave differently, the oldest one is usually the weak link, and you can retire it before it lets you down.

A good test is to swap in another cell. If the problem disappears, the old battery was the cause. If it stays, the charger, cable or processor needs a closer look.

How to fit your Naida CI Q70 Rechargeable Battery

1. Charge the new battery fully in your Naída CI PowerCel charger before first use.
2. Remove the old battery from the bottom of the Q70, holding the processor firmly.
3. Check the processor contacts. If you see corrosion, wipe gently with a dry cloth before fitting the new cell.
4. Align the PowerCel 230 with the base of the processor and press until you feel it click.
5. Start the processor as usual and run a quick listening check.
6. Label the new cell (a small dot of nail varnish works) so you can tell it apart from your older ones.

Labelling matters on a Q70, because many owners end up with a mix of batteries of different ages. Knowing which cell is new makes it much easier to spot the weak one later.

During the first week, keep an eye on how long the new Naida CI Q70 rechargeable battery runs compared with your old ones. A healthy new cell should clearly outlast a tired one; if it does not, contact us and we will help you work out why.

Q70 battery troubleshooting

Most Q70 power problems come down to three things: an ageing cell, dirty contacts, or moisture. Work through the table from the top, and test with a second Naida CI Q70 rechargeable battery whenever you can, because comparing two cells is the quickest way to find the fault.

What you notice	Likely cause	What to try
Sound drops in and out	Corroded or dirty contacts	Clean contacts on battery and processor; refit firmly
Battery empty by midday	Ageing cell	Compare with a second battery; replace the weaker one
Battery will not click in	Debris or a damaged latch	Check for dirt; do not force it; replace if the case is damaged
Charger shows an error	Dirty charger slot or failing cell	Clean the slot, try another slot, then try another battery
Marks return after cleaning	Moisture getting into the processor	Dry the processor overnight and replace the affected cell
Fault follows every battery	Processor, cable or charger issue	Check the cable and contact your clinic

Caring for your Naida CI Q70 rechargeable battery

Corrosion is the problem Q70 users mention most, so most of these tips are about keeping moisture away:

• Take the battery off at night and let both the cell and processor dry.
• Use a drying unit such as our electric dryer for the processor, especially after exercise or in humid weather.
• Clean the contacts weekly with a dry, lint-free cloth. Never use water or sprays.
• Avoid leaving batteries in hot places; heat shortens their life.
• Rotate two or three cells rather than wearing out one.

Rechargeable processor batteries commonly begin to fade after about a year of daily use. If your Q70 cells are older than that, a fresh one usually makes a noticeable difference.

Is a third-party battery safe on a Naída CI Q70?

This is a compatible replacement, not a part made by Advanced Bionics, and we never claim otherwise. It is built to the same connector, physical size and electrical specification as the PowerCel 230, so it sits and works on the Q70 the same way.

We test every Naida CI Q70 rechargeable battery before it ships: fit on the processor, charging and charge holding. If yours arrives faulty or is the wrong part, we replace it or refund you. Your audiologist remains the best person to ask about anything specific to your implant.

Be careful with unlabelled cells from auction sites. Users describe buying a Naida CI Q70 battery second hand without knowing its age or how it was stored. We sell new cells only, and we answer questions before and after you buy.

Building a Q70 kit that lasts

If you plan to keep your Q70 for years, think in terms of a small kit rather than one battery. Most of the wear parts on a Q70 can still be replaced:

Batteries	Two or three PowerCel 230 cells, or one 230 plus a Naida Q70 PowerCel 110 Mini for lighter days
Charger	A spare Naida CI Q70 PowerCel charger in case yours fails
Headpiece cable	Users report corrosion and wear here too; a Q70 UHP cable is worth keeping
Microphone	A Q70 T-Mic 2 if you use the T-Mic earhook

None of this is required, but every spare you hold is one less emergency if your clinic can no longer supply Q70 parts.

Can I charge it in my old Q70 charger?

Yes, it uses the standard Naída CI PowerCel charger.

Which part number does it match?

It matches the PowerCel 230 reference CI-5523.

Do you ship to my country?
