PowerOne P10 Hearing Aid Batteries (Size 10, Zinc‑Air)

Overview

PowerOne P10 batteries power the smallest hearing aids that use size 10 cells (yellow tab). They are mercury‑free zinc‑air batteries made in Germany, designed for clear, consistent output in compact devices such as CIC, IIC, and some mini RIC models.

Key benefits

• Stable 1.45 V output for reliable performance in digital hearing aids.
• Mercury‑free construction; safe for standard recycling programs that accept button cells.
• Easy handling with long pull tabs; color‑coded yellow for quick size identification.
• Made in Germany with tight quality controls for consistency across packs.

When to choose size 10

• Use if your hearing aid manual specifies size 10 or PR70 (yellow tab), typically for CIC/IIC and some ultra‑small RIC models.
• Avoid if your device requires size 312, 13, or 675, or if it has a built‑in rechargeable battery.
• If you stream audio heavily and want fewer changes, a larger battery size (e.g., 312) usually lasts longer between swaps.

Battery life: what to expect

• Typical use: 3–7 days per cell.
• Heavy use (high gain, frequent Bluetooth/telecoil streaming): 2–5 days.
• Lighter use: up to about a week.

Runtime depends on hearing loss level, device model, streaming time, and ambient temperature/humidity.

How to use (best results)

1. Peel the yellow tab only when ready to install.
2. Wait 60 seconds before inserting to fully activate the zinc‑air cell.
3. Insert with the “+” side up; close the battery door gently.
4. Open the battery door when not wearing the aids to reduce drain and allow ventilation.

Storage and safety

• Store at room temperature (50–77°F / 10–25°C) in a dry place; keep in the original pack until use.
• Do not refrigerate or expose to heat/humidity; avoid carrying loose cells with coins or keys (short‑circuit risk).
• Keep away from children and pets; button batteries are a swallowing hazard. Seek immediate medical help if ingested.
• Recycle used cells where button‑cell collection is available.

Compatibility

Fits hearing aids that specify size 10 (PR70). Common brands include Phonak, Oticon, Widex, ReSound, Signia/Siemens, Starkey, and others. Always confirm the required size in your user manual or with your hearing care provider.

Troubleshooting quick checks

• Device won’t power on: confirm the correct orientation (+ up), try a fresh cell, and ensure the battery door clicks fully closed.
• Short runtime: allow a full 60‑second air‑activation, open the door at night, and reduce streaming time where possible.
• Intermittent sound: check for moisture or debris in the battery compartment; replace the wax guard or filter if needed.

FAQ

How long do PowerOne P10 batteries last?

Most users see 3–7 days. Streaming, high amplification, and warm or humid environments shorten runtime.

Do I need to wait after pulling the tab?

Yes. Wait about 60 seconds before inserting so the cell reaches full operating voltage.

Are these rechargeable?

No. PowerOne P10 zinc‑air cells are single‑use. If you prefer rechargeables, ask your provider about a hearing aid model with built‑in lithium‑ion charging.

Can I store batteries in the fridge?

No. Refrigeration can cause condensation and reduced performance. Store at room temperature in a dry place.

How can I tell I need size 10?

Look for the yellow color code on your current batteries or in your manual; size 10 is also labeled PR70.
