CR2032

Identify the actual battery

CR2032 is a documented Lithium / manganese dioxide primary cell with a nominal voltage of 3 V. Its reference diameter is 20 mm and its reference height is 3.2 mm. These are nominal reference dimensions, not a promise that every manufacturer has identical tolerances.

This dataset describes a non-rechargeable bare cell, without solder tabs or wires. A tabbed or wired assembly requires a separate fit check.

What markings identify this type?

The dataset associates 5004LC, ECR2032, DL2032 with CR2032. The manufacturer may use a different label on the package. These references help identify the type; they do not certify the battery for a particular device.

Similar dimensions in this catalogue

The following types share the same reference diameter as CR2032. Their height, chemistry or voltage may differ. They are comparisons, not approved substitutes:

• BR2032 — BR2032: 3.2 mm high, 3 V; Lithium / polycarbon monofluoride.
• ML2032 — ML2032: 3.2 mm high, 3 V; Rechargeable lithium manganese dioxide.
• CR2025 — CR2025: 2.5 mm high, 3 V; Lithium / manganese dioxide.

Commonly confused markings and sizes

CR2025 and CR2016 also have a 20 mm reference diameter, but their heights are 2.5 and 1.6 mm, compared with 3.2 mm for CR2032. They are not the same physical size.

What to check before replacing CR2032

Read the original device marking, verify nominal voltage and chemistry, compare diameter and height, and check the contacts and load requirements. Same diameter, identical voltage, or a familiar brand prefix alone is not enough to establish interchangeability.

The available data contains no affirmative device-specific fit test for CR2032. A missing compatibility relation means “not assessed,” not “compatible.”

How reliable are these specifications?

Core type characteristics were compared with primary material from at least two independent publishers. This does not verify all model-specific values or physical suitability.
