BR2032

3V lithium coin cell

BR2032 matches CR2032 on size (20 × 3.2 mm) and 3 V nominal, but uses a different lithium chemistry subclass. It is not a retail rename of CR2032 — only fit BR2032 when the device or OEM specification names it.

Chemistry: lithium
Voltage: 3 V
Diameter: 20 mm
Thickness: 3.2 mm

Not a substitute

Same size and 3 V nominal; BR uses a different lithium chemistry subclass — only use when the device specifies BR2032

Rechargeables are not equivalents

Rechargeable coin cells (LIR, ML, VL, CTL and similar) are not drop-in replacements for disposable CR cells — voltage and charging requirements differ. Same size does not mean the same battery.

Edge thickness in the 20 mm family — thicker bar means thicker cell. Not to scale. Highlighted cell is this page.

Notes

Same 20 × 3.2 mm size and 3 V nominal as CR2032, but BR cells use a different lithium chemistry subclass (carbon monofluoride). Not an automatic CR2032 pack-label synonym — only use when the device or OEM specifies BR2032.
