Duracell Hearing Aid Battery Size 10 (DA10)

Size 10 (yellow tab) zinc‑air batteries power the smallest in‑ear hearing aids while keeping devices light and discreet. Duracell DA10 delivers stable 1.45 V output suitable for modern speech processing and feedback control in compact IIC/CIC and mini‑ITE/RIC designs.

When to Choose Size 10

• Use if your device specifies Size 10/PR70 and prioritizes a very small form factor (IIC, CIC, mini‑ITE/mini‑RIC).
• Good for light to moderate amplification and occasional streaming.
• Avoid if you need maximum runtime between changes—larger sizes (312/13/675) last longer.

Runtime Expectations

• Typical daily use: about 60–90 hours total (≈3–5 days) per battery.
• Heavy streaming/noisy environments: about 24–60 hours (≈1–3 days).
• Cold weather, high gain, tinnitus masking, or constant Bluetooth can shorten life.

Activation and Installation

1. Peel the yellow tab to start the zinc‑air reaction.
2. Wait about 1 minute before inserting to allow full activation.
3. Place the “+” side toward the battery door “+” marking; close gently without forcing.

How to Extend Battery Life

• Open the battery door overnight (if advised for your device) to reduce standby drain and moisture buildup.
• Enable power‑saving programs in quiet rooms; disable unnecessary streaming.
• Keep air holes and contacts clean and dry; wipe with a soft, dry cloth.
• Carry a spare pair when traveling or on long days.

Compatibility and Equivalents

• Also labeled PR70, IEC 7005ZD; universally color‑coded yellow for Size 10.
• For devices that specify Size 10 only—do not mix sizes.
• Primary (single‑use) cell; not rechargeable and not interchangeable with rechargeable hearing aid batteries.

Alternatives by Use Case

• Size 312 (brown): Similar footprint, longer life; common in RIC/ITE with more wireless use.
• Size 13 (orange): Higher capacity for frequent streaming or higher gain.
• Size 675 (blue): Longest life; typically for power BTE and some bone‑anchored systems.

Technical Snapshot

Chemistry	Zinc‑air
Nominal voltage	1.45 V
Standard designation	Size 10 / PR70 (yellow tab)

Troubleshooting

• Device won’t start: Confirm tab removal, wait 1 minute, check polarity, and close the door fully.
• Muffled or intermittent sound: Replace the battery, then inspect wax guards and microphone ports for debris.
• Short runtime: Reduce streaming where possible and verify the device is configured correctly; consider Size 312 or 13 if your model supports it.

Safety and Storage

• Store sealed at room temperature; avoid heat, humidity, and metal objects that can short terminals.
• Keep out of reach of children and pets. If swallowed, seek immediate medical attention or call a poison helpline.
• Recycle or dispose of used cells promptly according to local guidance.

FAQs

Are Size 10 and PR70 the same?

Yes. PR70 is the standard code for Size 10 hearing aid batteries and uses the yellow tab.

How long should I wait after removing the tab?

About 1 minute. This allows air to activate the battery chemistry for full performance.

Can I re‑tab a battery to save it for later?

No. Once activated, the reaction continues even if you replace the tab.

Are these rechargeable?

No. DA10 is a single‑use zinc‑air cell. Only use rechargeables if your hearing aids are specifically designed for them.

Why does my battery life vary day to day?

Usage (streaming, noise levels), device settings, temperature, and humidity all affect runtime.
