Energizer Hearing Aid Batteries Size 312

Energizer Hearing Aid Batteries Size 312 (Brown)

Energizer size 312 (brown) zinc‑air batteries provide steady 1.45 V power for popular receiver‑in‑canal (RIC) and mini‑BTE hearing aids. They are mercury‑free, easy to handle, and designed to support modern features like speech enhancement, directional microphones, and wireless streaming.

When to Choose Size 312

• Use if you wear RIC or mini‑BTE devices and want a small form factor with weekly change intervals.
• Avoid if your device specifies a different size (10, 13, or 675) or uses a proprietary rechargeable system.
• Consider size 13 if you stream heavily or need longer intervals between changes and your device supports it.

Specs at a Glance

Size / Color Code	312 / Brown
Chemistry	Zinc‑air (mercury‑free)
Nominal Voltage	1.45 V
Typical Devices	RIC and mini‑BTE hearing aids

Expected Runtime and Planning

Most users get about 5–10 days of all‑day wear per cell. Life varies with device model, gain settings, environmental noise, and streaming time.

• Light streaming and quiet days: toward the upper end of the range.
• Frequent Bluetooth audio or noisy venues: toward the lower end.
• Simple plan: pick a weekly swap day (for example, every Sunday) and carry a spare pair for travel or events.

Size	Color	Typical Runtime	Common Fit
10	Yellow	~3–7 days	CIC/IIC, micro‑RIC
312	Brown	~5–10 days	RIC, mini‑BTE
13	Orange	~6–14 days	RIC, BTE
675	Blue	~9–20 days	High‑power BTE, processors

Activation and Handling (1‑Minute Routine)

1. Peel the brown tab completely to expose the air holes.
2. Wait about 60 seconds before inserting the battery to fully activate the zinc‑air chemistry.
3. Insert with clean, dry hands and confirm correct polarity.
4. If your device has a battery door, open it overnight to reduce idle drain and moisture.

• Keep tabs on until use; do not pre‑activate.
• Wipe battery contacts and door pads with a dry, lint‑free cloth during changes.

Storage and Stocking

• Store sealed packs at room temperature in a dry place; avoid bathrooms and refrigerators.
• Carry a spare pair in a wallet card or case; keep cells in their packaging (do not store loose with coins or keys).
• Pack options: wallet cards (6–8 cells) for everyday carry, value packs (12–24) for home, and clinic sleeves for professional use.

Compatibility and Alternatives

• Match the color code and size markings: brown = 312. Never force a fit.
• Not rechargeable: do not place disposable zinc‑air cells into rechargeable hearing aid bays.
• If runtime is consistently short and your device supports it, ask your provider about moving to size 13 or a rechargeable hearing aid model.

Safety and Disposal

• Ingestion hazard: keep batteries away from children and pets. If swallowed, seek immediate medical attention.
• Use child‑resistant packaging and store out of sight and reach.
• After use, tape the terminals or place cells back into the empty card before proper disposal. Follow local guidance for recycling or disposal.

Troubleshooting

• New cell, no power: ensure the tab is fully removed, wait 60 seconds, check polarity, and clean contacts. Try a second cell to rule out door/contact issues.
• Intermittent cut‑outs: confirm the battery door latches fully and that air holes are not blocked by oils or debris.
• Shorter life this week: heavy streaming, higher gain, or noisy environments increase current draw; pre‑swap before long events.

FAQ

How long do Energizer size 312 batteries typically last?

About 5–10 days of all‑day wear, depending on your device settings, environment, and streaming time.

Do I need to wait after peeling the tab?

Yes. Waiting about 60 seconds lets oxygen activate the cell, improving stability and practical runtime.

Can I use these in any hearing aid?

Use only if your hearing aid specifies size 312 (brown). Check your manual or ask your hearing care provider.

Are size 312 batteries rechargeable?

No. These are single‑use zinc‑air cells. If you want rechargeability, consider a hearing aid designed for rechargeable batteries.

What’s the best way to store spares?

Keep sealed packs at room temperature in a dry drawer. Do not refrigerate. Carry a sealed wallet card for travel.
