  • Use instead of CR1225

    CR1220

    No

    No: CR1220 is 0.5 mm thinner than CR1225.

    Same 12.5 mm diameter, but CR1220 is 2 mm against 2.5 mm: the contact spring may not reach it.

    CR1220: 12.5 mm3 × 2 mm3, 3 V3

Questions

What is the CR1225 battery equivalent?

DL1225 name the same 12.5 × 2.5 mm lithium coin cell as CR1225. Any maker's cell under one of these codes fits.

Is CR1220 the same as CR1225?

No. CR1220 is 0.5 mm thinner than CR1225. Same 12.5 mm diameter, but CR1220 is 2 mm against 2.5 mm: the contact spring may not reach it.
