Frequently Asked Questions

Is CR1632 the same as CR2032?

No. Same 3.2 mm height and 3V lithium class, different diameter (16 mm vs 20 mm). They are not interchangeable.

What devices use CR1632?

Some car key fobs, compact sensors, and calculators. If the old cell is marked CR1632 / DL1632, do not buy CR2032 as a “close enough” substitute.

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.

Selection notes

Measure the old cell or the tray. A CR2032 will not seat in a 16 mm fob, and a CR1632 rattles in a 20 mm holder. Brand labels include DL1632 and ECR1632.
