  Operates across 0°C to 50°C for varied everyday conditions

Applications

• 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

How does ambient temperature affect delivered capacity?

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

What internal electrical characteristic impacts response at different frequencies?

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

What physical attributes determine compatibility with Compact devices?

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

How is expected service life represented for typical use?

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

Warning

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