Energizer Hearing Aid Batteries

Overview

Energizer Hearing Aid Batteries are mercury‑free zinc‑air cells designed for modern hearing instruments. They deliver stable 1.45 V output for features like noise reduction, directionality, and wireless streaming. Choose the correct size for your device, follow a simple activation routine, and plan swaps based on your typical day.

Choose the Right Size

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

Runtime varies with amplification needs, streaming time, volume, and environment. If your days include heavy streaming or loud venues, consider a larger size if your device supports it.

How to Use for Best Results

1. Confirm the exact size your device requires (10, 312, 13, or 675). Do not mix sizes.
2. Peel the tab to activate, then wait about 60 seconds before inserting.
3. Insert with correct polarity; close the battery door fully.
4. At night, open the battery door (if applicable) to reduce idle drain and let moisture escape.
5. Replace both left and right cells together to keep performance consistent.

Care, Storage, and Stocking

• Keep batteries sealed until use; activation starts when air reaches the cell.
• Store at room temperature in a dry place. Avoid refrigerators, freezers, and humid bathrooms.
• Handle with clean, dry hands to avoid blocking air inlets with oils or debris.
• For everyday readiness, keep one open card in use and one sealed backup. For travel, carry at least two spare cells per device.

When to Choose (and When to Avoid)

• Choose if your hearing aids specify zinc‑air disposables and you want predictable all‑day power without charging.
• Consider a larger size (13 or 675) if your device supports it and you stream often or work long shifts.
• Avoid if your instruments are rechargeable‑only; use the charger and batteries designed for that system.
• For cochlear or specialty processors, use only the size listed by the manufacturer (often 675) and follow the device manual.

Pros and Cons

• Pros: Stable 1.45 V output, widely available, color‑coded sizes, mercury‑free, no charging downtime.
• Cons: Single‑use waste, performance can shorten with heavy streaming, must wait after activation, sensitive to humidity and blocked air inlets.

Troubleshooting

• New cell, no power: Ensure tab is fully removed, wait 1 minute, check polarity, and clean contacts gently.
• Intermittent cut‑outs: Confirm the battery door latches; inspect for debris or oils covering air holes.
• Shorter than usual runtime: More streaming, louder environments, or higher volume can reduce life; consider sizing up if supported.

Safety and Disposal

• Keep batteries away from children and pets. If swallowed, seek immediate medical attention.
• Use child‑resistant packaging and store out of sight and reach.
• Tape terminals or return used cells to the original card before disposal. Follow local disposal or recycling guidance.

FAQ

Do I need to wait after peeling the tab?

Yes. Wait about 60 seconds to let oxygen activate the cell; this typically improves runtime and stability.

Can I store hearing aid batteries in the fridge?

No. Store at room temperature in a dry place to avoid condensation and performance issues.

Are these rechargeable?

No. Zinc‑air hearing aid batteries are single‑use. If you want rechargeability, ask your provider about devices designed for rechargeable systems.

How many spares should I carry?

Carry at least two spare cells per device, especially if you plan to stream audio or attend long events.

Will mixing brands or sizes cause issues?

Use only the exact size your device specifies and avoid mixing brands within the same device to keep performance consistent.
