Duracell PR48 Button Battery, 1.4 V, 7.9 mm Diameter, 6 Pack

This button battery is a zinc-air cell designed for low‑drain wearable devices and hearing instruments, delivering a nominal voltage of 1.4V and supplied as a six‑pack. It operates within a typical ambient temperature range and uses flat termination for surface contact. The pack meets recognised ANSI and IEC approvals and is sized for Compact electronic applications requiring lightweight power sources.

• 300 mAh capacity provides extended service between replacements
• 1.4V nominal voltage supports stable low‑voltage circuitry
• Flat termination ensures straightforward mounting and contact
• Lightweight at 800mg reduces wearable‑device mass constraints
• Operates across 0°C to 50°C for varied everyday conditions

• Suitable for behind‑the‑ear hearing instruments using zinc‑air cells
• Ideal for diagnostic equipment requiring small‑format power
• Used with personal audio devices needing a low‑voltage supply
• Can be used for portable sensors with limited space
• Suitable for replacement in small medical electronics

Delivered capacity varies with applied load and operating temperature, reducing at extremes and following the discharge characteristics provided as examples.

The typical internal impedance is 7.5ohm measured at 1kHz, influencing transient performance under varying loads.

Compatibility depends on the cell diameter of 7.9mm and height of 5.4mm, together with flat terminals for correct contact.

Service hours are illustrated by discharge curves at 21°C for several duty cycles, showing performance under specified load patterns.

Keep button batteries out of the reach of children. Consult a doctor immediately if ingested.
