  • Use instead of CR2412

    CR2430

    No

    No: CR2430 is 1.8 mm taller than CR2412.

    Same 24.5 mm diameter, but CR2430 stands 3 mm against 1.2 mm: the case back presses on it or does not close.

Warnings from the makers

Keep away from children

“Keep batteries out of reach of small children. Should a child swallow a battery, consult a physician immediately.”[4]

Questions

What is the CR2412 battery equivalent?

ECR2412, DL2412 name the same 24.5 × 1.2 mm lithium coin cell as CR2412. Any maker's cell under one of these codes fits.

Is CR2430 the same as CR2412?

No. CR2430 is 1.8 mm taller than CR2412. Same 24.5 mm diameter, but CR2430 stands 3 mm against 1.2 mm: the case back presses on it or does not close.
