For the Model 102B, does anyone know what the coin battery number is in the US?

Hi Rick,

I trust you received my email response yesterday?

It's a Panasonic CR1220 3V or equivalent. We use the equivalent one from Renata ourselves.

The 12 code refers to the fact the battery is 12.5mm in diameter. The 20 refers to it being 2.0mm in height.

Duracell will refer to it as a DL1220
Energizer as a ECR1220
Maxell and Sony both refer to it as a CR1220.

For example, see https://www.digikey.com/en/products/filter/batteries-non-rechargeable-primary/90?s=N4IgTCBcDaIMICUC0BGMYAMIC6BfIA

See "Appendix F - How to replace the Lithium coin cell battery" of the User Manual pages 233-235
