• Chemistry: Zinc-air (not rechargeable)
• Nominal Voltage: 1.45 V
• Typical Capacity: ~300–310 mAh (varies by device load)
• Dimensions: 7.9 mm diameter × 5.4 mm height
• Runtime: About 3–10 days per cell based on use
• Shelf Life: Typically up to 3 years when sealed
• Packaging: 6-pack cards; bulk multipacks available
• Made in Germany by VARTA Microbattery
• Cross-refs: PR48, ZA13, 13A, L13ZA, A13

When to Choose These

• Use if your hearing aid specifies size 13/PR48 (orange tab).
• Good fit for devices with wireless streaming and feedback management that benefit from stable 1.45 V.
• Prefer disposable cells over device-specific rechargeable systems.

Consider Alternatives

• Avoid if your device uses a different size (10, 312, or 675) or has an integrated rechargeable battery.
• Rechargeable size 13 NiMH cells exist but are only suitable if your hearing aid explicitly supports them, and they typically provide shorter runtime per charge.

Expected Runtime (Typical Scenarios)

• Light use (no streaming, moderate volume): ~7–10 days
• Moderate use (occasional streaming/calls): ~4–7 days
• Heavy use (frequent streaming, high gain): ~2–4 days

Actual life depends on your hearing aid model, amplification level, wireless features, and environment (temperature, humidity, altitude).

Usage Tips for Best Performance

• Activation: Remove the tab and wait 1–2 minutes before inserting to allow full air activation.
• Daily care: Open the battery door or switch the aid off overnight to reduce standby drain and moisture buildup.
• Storage: Keep sealed at room temperature; avoid heat, humidity, and refrigeration. Do not carry loose batteries with keys/coins.
• Contact care: Keep the battery compartment clean and dry; wipe contacts gently if you notice intermittent power.
• Disposal: Recycle where available. Never incinerate.

Compatibility

Designed for any hearing aid that calls for size 13/PR48 (orange). Common in many BTE and larger ITE/ITC models from brands such as Phonak, Signia, Oticon, Widex, and ReSound. Check your manual or the existing battery’s color code to confirm.

Pros and Cons

• Pros: Stable 1.45 V output, widely compatible, mercury-free, long handling tabs, reliable performance for wireless/streaming aids.
• Cons: Begins discharging once tab is removed; runtime can shorten in very dry, very humid, or high-altitude conditions; not rechargeable.

FAQ

How long do PowerOne P13 batteries last?

Most users see 3–10 days. Heavy streaming and high amplification reduce life; light, non-streaming use extends it.

Should I let the battery “breathe” before use?

Yes. After removing the tab, wait 1–2 minutes before inserting. This allows oxygen to activate the zinc-air chemistry for full capacity.

Can I recharge these batteries?

No. Zinc-air cells are not rechargeable. Only use rechargeable batteries if your hearing aid specifically supports them.

Why did my battery die early?

Common causes include frequent Bluetooth streaming, high gain settings, extreme humidity/altitude, or inserting immediately after tab removal. Try waiting 2 minutes after tab removal and storing spares properly.

Is refrigeration recommended?

No. Store at room temperature in original packaging. Refrigeration can introduce moisture and shorten life.

Safety Notes

• Keep away from children and pets; coin-sized batteries are a choking and ingestion hazard.
• Seek immediate medical help if a battery is swallowed.
• Do not short-circuit, recharge, or dispose of in fire.
