Duracell LR44 (76A) Alkaline Button Battery – 1.5V for Small Electronics

The Duracell LR44 (also listed as 76A, A76, AG13, or L1154) is a 1.5V alkaline button cell sized for compact devices. It’s a common fit for digital thermometers, laser pointers, calculators, small toys, and some watches. If your device or old battery says LR44/A76/AG13/76A/L1154, this cell is the intended alkaline replacement.

Quick Specs

• Chemistry: Alkaline (primary, non-rechargeable)
• Voltage: 1.5V nominal
• Size: ~11.6 mm diameter × ~5.4 mm height
• Common designations: LR44, A76, 76A, AG13, L1154
• Typical capacity: ~110–150 mAh (varies by load and temperature)

When to Choose LR44 vs. Alternatives

• Choose LR44 (alkaline) if your device specifies LR44/A76/AG13 and is low-to-moderate drain (e.g., calculators, thermometers, simple toys).
• Choose SR44/357 (silver oxide) if the device calls for SR44/357/303 or needs very stable voltage for precision timing or sensors (e.g., some cameras, instruments).
• Avoid substituting 3V cells like CR1/3N; they are different size and voltage.

Expected Runtime (Typical Scenarios)

Note: Actual life varies with device design, duty cycle, and ambient temperature.

Installation Checklist

1. Confirm the code: LR44/A76/AG13/76A/L1154 on the device, manual, or old battery.
2. Match polarity: The flat “+” cap faces the “+” marking inside the compartment.
3. Clean contacts: Wipe terminals with a dry, lint-free cloth before seating.
4. Secure fit: Ensure the cell is fully seated under spring tabs or contact clips.
5. Test: Power on and check for a stable display or normal operation.

Care, Storage, and Safety

• Store unused cells in original packaging at room temperature, dry and away from metal objects.
• Do not mix old and new cells or different brands/chemistries in one device.
• Remove batteries from devices stored long term to reduce leakage risk.
• Keep away from children and pets. If swallowed, seek immediate medical help; do not induce vomiting.
• Tape both sides of used cells before recycling to reduce short-circuit risk.

Troubleshooting

• Dim or fading display: Replace the cell; confirm correct polarity and clean contacts.
• Intermittent power: Reseat the battery, gently adjust contact springs if flattened, and remove any oxidation.
• Short runtime: High-drain use (e.g., continuous laser) reduces life; carry spares or consider a device designed for larger batteries.

FAQ

Are LR44 and AG13 the same?

Yes. AG13 is a common cross-reference for LR44/A76/76A/L1154 alkaline button cells.

Can I use SR44/357 instead of LR44?

Only if your device allows it. SR44/357 is silver-oxide with similar size but different discharge behavior. Follow the device’s recommendation.

Is LR44 rechargeable?

No. Do not recharge alkaline button cells. Use only primary LR44 in devices that specify it.

What temperatures work best?

Room temperature is ideal. Very cold conditions reduce available capacity; warm the device and battery to normal room temperature for best results.

How should I dispose of used LR44 batteries?

Tape the terminals and recycle through battery collection programs per local guidelines. Avoid trash disposal where prohibited.

Summary

Duracell LR44 (76A) is a reliable 1.5V alkaline button cell for many small devices. Match the code, install with correct polarity, and follow storage and safety steps to maximize runtime and protect your device.
