Powerone Batteries

PowerOne hearing aid batteries

PowerOne supplies mercury‑free zinc‑air button cells designed specifically for hearing aids. Manufactured in Germany by VARTA, these batteries deliver stable 1.45 V output and reliable runtime across modern devices, including models with wireless streaming and noise management features.

Key features at a glance

• Mercury‑free zinc‑air chemistry with consistent 1.45 V for stable device performance.
• Rust‑resistant stainless‑steel casing to help prevent corrosion in humid or sweaty conditions.
• Long sealed shelf life (typically 3–4 years) when stored properly.
• Color‑coded sizes for easy matching: 10 (yellow), 312 (brown), 13 (orange), 675 (blue).

Choosing the right size

Match the size specified by your hearing aid manufacturer. Color codes are standardized across brands.

Size	Color code	Typical devices	Typical runtime
10	Yellow	Very small IIC/CIC and mini RIC	About 3–7 days depending on use
312	Brown	RIC and compact BTE	About 5–12 days depending on use
13	Orange	BTE and power RIC	About 6–14 days depending on use
675	Blue	High‑power BTE and some cochlear implant processors	About 9–20 days depending on use

Note: Heavy streaming, higher amplification, and frequent program changes can shorten runtime.

When to choose PowerOne

• Use if your hearing aids require disposable zinc‑air cells and you want dependable, mercury‑free batteries.
• Use size 675 if your cochlear implant or power BTE specifies it; some implants may call for “implant‑grade” cells—follow the device manual.
• Consider alternatives if your hearing aids are designed for rechargeable batteries or if your clinic recommends a specific specialty cell.

Setup and care tips

1. Wash and dry hands. Remove the tab only when ready to use.
2. Allow the battery to “air up” for 1–2 minutes before insertion to reach full power.
3. Insert with the + side up. Close the battery door fully.
4. Open the battery door or turn the aids off when not in use to reduce drain.
5. Store in original packaging at room temperature and low humidity. Do not refrigerate or carry loose with coins/keys.

Pros and cons

• Pros: Stable voltage, mercury‑free, reliable performance, long sealed shelf life, widely available sizes.
• Cons: Non‑rechargeable; performance can be affected by very dry or very humid conditions; runtime varies with streaming and amplification needs.

Safety and recycling

• Keep batteries away from children and pets; button cells are a choking and ingestion hazard.
• If swallowed or inserted into the nose/ear, seek immediate medical help or contact Poison Control (U.S. 1‑800‑222‑1222).
• Do not attempt to recharge, disassemble, or incinerate. Recycle used batteries where local programs exist.

FAQ

Are PowerOne batteries rechargeable?

No. PowerOne zinc‑air cells are single‑use. If your hearing aids are rechargeable, use the charger and batteries specified by the device manufacturer.

How long should I wait after removing the tab?

Wait about 1–2 minutes before inserting to allow the zinc‑air chemistry to fully activate.

My new battery seems weak. What should I check?

Confirm the tab was removed and you waited for activation, ensure the battery is inserted with the + side up, clean the contacts if needed, and verify the battery door closes securely. Extremely dry or very humid environments can also impact performance.

Can I mix brands or batches?

Using different brands is generally fine as long as the size matches. For devices that use two cells, replace both at the same time and avoid mixing old and new batteries.

How should I store spares?

Keep sealed batteries in their original packaging at room temperature, away from moisture and heat. Do not store in the refrigerator.
