Frequently Asked Questions

Can I use a CR2032 instead of CR1620?

No. CR2032 is 20 mm wide and 3.2 mm thick. CR1620 is 16 × 2.0 mm. They do not share a holder.

Should I always trust cross-reference charts?

Use this guide as a starting point, then confirm with your device manual or manufacturer. Voltage, chemistry, and physical fit must all match for safe operation.
