PowerOne ACCU Plus Size 10 Rechargeable Hearing Aid Batteries

Replace disposable size 10 zinc‑air cells with reusable NiMH power. PowerOne ACCU Plus size 10 batteries are designed for small CIC/ITE hearing aids that support 1.2 V rechargeable cells and are charged with PowerOne Pocket or Pen chargers.

Who should choose these

• Users of size 10 (yellow) hearing aids that explicitly support rechargeable NiMH cells.
• Light to moderate daily power needs (limited streaming/Bluetooth use).
• Those wanting to reduce waste and ongoing battery purchases.

Who should avoid these

• Hearing aids that require zinc‑air only or use ZPower/Oticon-specific rechargeable systems.
• Users needing all‑day (12+ hours) heavy streaming or very high amplification on a single charge.
• If you need in‑aid or manufacturer‑specific lithium‑ion charging cases (these cells charge only in PowerOne chargers).

What to expect vs zinc‑air

• Runtime: Rechargeable size 10 NiMH (~11 mAh) typically delivers hours per charge; zinc‑air size 10 (~80–100 mAh) often lasts several days per battery.
• Voltage: 1.2 V (NiMH) vs ~1.4 V (zinc‑air). Use only if your hearing aid is approved for rechargeables.
• Convenience: Daily charging instead of frequent battery purchases.
• Cost/waste: Fewer disposables; plan for the charger and eventual cell replacement after hundreds of cycles.

Compatibility notes

• Fits devices that accept size 10 and support 1.2 V NiMH cells. Always confirm in your hearing aid manual or with your audiologist.
• Not for ZPower plates/chargers, Oticon charger systems, or any built‑in lithium‑ion charging cases.
• Charge only in PowerOne Pocket or Pen chargers; do not attempt to charge inside the hearing aid.

How to use

1. Fully charge before first use (about 2.5–5 hours).
2. Insert the charged battery into the hearing aid; unlike zinc‑air, there is no wait time for air activation.
3. Plan daily charging. A 30–60 minute top‑up can provide a few extra hours if needed.
4. Carry a spare charged cell for days with heavy streaming or long wear times.

Care, safety, and longevity

• Store and charge at room temperature; keep dry and away from heat.
• Keep away from children and pets; button cells can be a swallowing hazard.
• Do not mix chemistries (avoid charging zinc‑air or mixing with other rechargeable brands/voltages).
• Clean battery and device contacts with a dry cloth to maintain performance.
• Recycle responsibly at battery collection points when capacity declines.

Alternatives

• If you need multi‑day runtime per cell: use disposable zinc‑air size 10.
• If you want true all‑day, high‑drain use with charging in a case: consider hearing aids with integrated lithium‑ion batteries (device‑specific).

FAQ

How long will a charge last?

Typically 6–12 hours per charge. Heavy streaming, noise processing, and higher gain settings reduce runtime.

Will 1.2 V work in my hearing aid?

Yes, if your device is approved for rechargeable cells. Some devices not designed for 1.2 V may show a low‑battery warning early or may not perform correctly—check your manual.

Can I use any charger?

No. Use PowerOne Pocket or Pen chargers. Do not charge in the hearing aid or with ZPower/Oticon systems.

How many cycles can I expect?

Up to about 800 under ideal conditions. Actual life depends on depth of discharge, charging habits, and storage conditions.

What if my runtime is too short?

Reduce streaming time, carry a second charged cell, or switch to zinc‑air size 10 for longer single‑use runtime.
