BR2450 battery replacement and equivalents

Omnergy BR2450 manufacturer example: 3 V lithium carbon monofluoride, nominal format 24.5 × 5 mm. Verify the exact manufacturer's specification; this example does not establish every BR2450's rating or fit. Match the complete specification before treating another marking as a replacement.

Typical applications

  • Long-life memory backup
  • meters
  • low-drain electronics

Replacement decision

Resolve the original marking to this profile, then confirm nominal voltage, chemistry, dimensions, polarity and any drain or terminal suffix. Capacity alone does not establish interchangeability.

Same-size batteries to review carefully

These profiles share the nominal physical envelope. They are not automatically equivalent.
