Duracell Hearing Aid Battery 13 (DA13) — Robust Zinc-Air Power for BTE and RIC Devices

Duracell Size 13 (DA13) hearing aid batteries—identified by the orange tab—deliver the steady voltage and capacity that many behind-the-ear (BTE) and receiver-in-canal (RIC) instruments require. If your fittings include directional microphones, advanced noise management, tinnitus features, or frequent audio streaming, Size 13 is a popular choice thanks to its balance of runtime and form factor. Designed for predictable, day-to-day performance, these zinc-air cells help maintain consistent amplification and natural-sounding speech.

What Makes Size 13 a Workhorse?

• Stable output: Zinc-air chemistry supports a flatter discharge curve for consistent clarity.
• More capacity than smaller sizes: Suitable for users who rely on features and longer daily wear.
• Widely specified: Many BTE/RIC platforms are tuned for 13 cells to optimize space and performance.

How Zinc-Air Activation Works

Peeling the orange tab admits oxygen, activating the battery. Wait briefly to allow full activation, then install. Once started, the chemical reaction continues even when the device is off; re-sticking the tab will not pause aging. For best results, remove the tab only when you’re ready to use the battery.

Common Applications

• BTE and RIC hearing aids designed for Size 13
• Devices with frequent Bluetooth®/wireless streaming
• Programs requiring strong amplification or complex processing

Technical Snapshot

• Chemistry: Zinc-air
• Nominal voltage: ~1.45 V
• Designation: 13 / PR48 (orange tab)
• Type: Primary (single-use) hearing aid battery

Installation Best Practices

1. Peel the orange tab and allow a short “air-up” period.
2. Insert with the correct polarity; the “+” typically faces the door.
3. Close gently and run a quick listening check in quiet and noisy rooms.

Ways to Extend Battery Life

• Nighttime care: Open the battery door to reduce drain and let moisture escape.
• Smart settings: Use power-saving or program shortcuts your clinician recommends.
• Keep it clean: Clear wax and debris from battery doors and microphones to prevent over-amplification and extra draw.
• Carry spares: Reliable backup ensures you never miss conversations.

Troubleshooting

• Sudden shutdown: Ensure the battery door snaps fully closed; re-seat the cell.
• Distorted audio: Replace with a fresh battery and check for moisture after exercise or weather exposure.
• Shorter runtime than expected: Heavy streaming, strong amplification, or frequent program changes increase consumption.

Safety & Storage

• Store at room temperature; avoid heat and humidity.
• Keep out of reach of children and pets; button batteries can be hazardous if swallowed.
• Recycle or dispose properly following local guidance.

FAQs

Is PR48 the same as Size 13?

Yes—PR48 is a standard cross-reference for Size 13 (orange tab).

Why does my battery drain faster some days?

Streaming, noise conditions, directional mic use, and feedback control all change the power profile. Variability is normal.

Should I clean the battery with alcohol?

No. A dry, lint-free wipe is sufficient; solvents can harm labels or seals.

Summary

Duracell 13 (DA13) delivers robust, stable power for feature-rich hearing instruments. Activate only when needed, install with correct polarity, and follow simple care habits to enjoy consistent, comfortable listening throughout your day.
