Understanding CR2016 before replacement

Identify the actual battery

CR2016 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 1.6 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 5000LC, ECR2016, DL2016 with CR2016. 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 CR2016. Their height, chemistry or voltage may differ. They are comparisons, not approved substitutes:

  • ML2016H — ML2016H: 1.6 mm high, 3 V; Rechargeable lithium manganese dioxide.
  • ML2020 — ML2020: 2 mm high, 3 V; Rechargeable lithium manganese dioxide.
  • VL2020 — VL2020: 2 mm high, 3 V; Rechargeable lithium vanadium oxide.

What to check before replacing CR2016

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 CR2016. 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.

Common questions

What size is CR2016?

Ø 20 × 1.6 mm

Can CR2016 be recharged?

No. Do not charge primary cells.

Can CR2016 replace another battery?

Not on the basis of size or matching names alone. Check the exact device requirements and the directed compatibility notes. This catalogue does not contain a guaranteed device-fit recommendation for CR2016.

How does CR2016 differ from ML2016H?

CR2016 and ML2016H have reference heights of 1.6 mm and 1.6 mm respectively, and nominal voltages of 3 V and 3 V. Their chemical systems are Lithium / manganese dioxide and Rechargeable lithium manganese dioxide. These comparisons do not establish a permitted replacement.
