FAQ

What do buyers ask about button cells?

How do I find the right button cell?

Match the number printed on your old cell (or in the device manual) in the cross-reference table on this page — e.g. LR44 = AG13 = A76 = 357. Each model page also lists its own compatibility list.

What button cell sizes do you manufacture?

28 models across three chemistries: lithium CR (3.0V), alkaline AG/LR (1.5V) and silver oxide SR (1.55V).

Are your button cells mercury-free?

Yes. We produce 0% mercury alkaline button cells and mercury-free lithium & silver-oxide button cells on Japanese MITSUBISHI full-automatic lines.

What voltage is a CR2032?

A CR2032 is a 3.0V lithium coin cell, {cr2032.diameter} diameter x {cr2032.thickness}, with {cr2032.capacity} capacity.

Can I get custom label & packaging?

Yes. Custom brand label, blister and packaging for OEM / ODM and private-label button cell projects.
