Duracell Hearing Aid Battery 10 (DA10) — Ultra-Small Zinc-Air Power for Discreet Devices

Size 10 hearing aid batteries—marked by the yellow tab—are tailored for the smallest, most discreet hearing instruments. Duracell DA10 supports ultra-compact in-the-ear (ITE), completely-in-canal (CIC), and mini-RIC designs where space is at a premium. Although its can is tiny, Size 10 still provides the stable zinc-air voltage modern processors expect for speech enhancement, feedback control, and reliable day-to-day operation.

Why Size 10?

• Minimal size, maximum discretion: Fits ultra-small shells and deep canal placements.
• Stable output: Zinc-air chemistry helps maintain clear, natural sound across the discharge curve.
• Lightweight comfort: Keeps tiny devices balanced and comfortable for long wear.

Best-Fit Applications

• CIC, IIC, and mini-ITE instruments engineered for Size 10
• Light to moderate amplification profiles
• Occasional streaming or simple wireless features

Technical Snapshot

• Chemistry: Zinc-air
• Nominal voltage: ~1.45 V
• Designation: 10 / PR70 (yellow tab)
• Type: Primary (single-use)

Activation & Installation

1. Peel the yellow tab to start the reaction; let it breathe briefly.
2. Match polarity; most devices place the “+” toward the door.
3. Close gently—never force a tight door as contacts can bend.

Getting the Most from Size 10

• Open the door overnight (as advised by your clinician) to reduce standby drain and moisture buildup.
• Use power-saving programs in quiet settings to extend life.
• Manage expectations: The smallest cells have the shortest runtimes; carry a spare pair.
• Keep ports clear: Moisture or debris near air holes can reduce performance.

Troubleshooting

• Device won’t start: Confirm tab removal and polarity; re-seat the cell and close the door fully.
• Muffled sound: Replace the battery and check for wax guards or microphone obstructions.
• Inconsistent runtime: Streaming or noisy environments can shorten life; usage patterns matter.

Safety & Storage

• Store sealed at room temperature; avoid bathrooms and hot cars.
• Keep away from children and pets; seek immediate care if swallowed.
• Dispose or recycle used cells promptly and safely.

FAQs

Are PR70 and Size 10 the same?

Yes—PR70 is a standard code for Size 10 (yellow tab).

Should I re-tab a battery for later use?

No. Once activated, the reaction proceeds; re-tabbing won’t restore unused capacity.

Can Size 10 handle streaming?

Some devices stream with Size 10, but expect shorter runtimes than larger cells.

Summary

Duracell DA10 powers ultra-small hearing instruments with steady zinc-air voltage. Activate only when needed, keep contacts clean, and carry spares to ensure discreet devices stay ready for hearing clarity whenever you need it.
