Comparison

CR2032 vs BR2032

Same 20 × 3.2 mm size and 3 V nominal — different lithium chemistry subclasses. Not an automatic pack-label swap.

At a glance

Question	Answer
Same battery?	Same cell family / labels
Same dimensions?	Yes
Same chemistry?	Yes
Same voltage?	3 V
Direct substitute?	Yes when the device names any of these labels

What is the same

Both are about 20 mm across and 3.2 mm thick at 3 V nominal, so they can look identical in a drawer.

What is different

CR cells (lithium manganese dioxide) and BR cells (lithium carbon monofluoride subclass) are different chemistries with different discharge behaviour. Matching size alone is not typed equivalence.

Use the code the device or OEM manual names. Do not treat BR2032 as a pack label for CR2032 (or the reverse).

How these codes relate

Same battery, pack labels, or same size with a different type — not a generic “compatible with” list.
