CR2016

CR2016 has a 20 mm diameter and 1.6 mm nominal height. Another 3 V lithium coin cell is not automatically interchangeable.

Answer

CR2016, DL2016, ECR2016 are the supported exact aliases for one 20 × 1.6 mm lithium coin cell. No other family is treated as an automatic replacement.

Top profile · Ø 20 mm

Side profile · 1.6 mm high

Original proportional profiles. Scale is consistent within this diagram; screen size is not a physical ruler.

Format: Lithium coin cell
Dimensions: 20 × 1.6 mm
Voltage: 3 V nominal
Chemistry: Lithium manganese dioxide
Drain context: Low continuous drain; pulse performance is product-specific
Rechargeable?: No — primary cell; do not recharge.
Capacity context: Typical product figure near 90 mAh; verify load, cut-off and temperature in a current datasheet.
Confidence: High

CR2016 · DL2016 · ECR2016Exact equivalentThese evidence-backed markings resolve to this one canonical record and share its cited physical and electrical specification.

CR2012Not equivalentThe physical envelopes differ (20 × 1.6 mm versus 20 × 1.2 mm). Do not force, stack or infer equivalence from a shared diameter or code pattern.

CR2025Not equivalentThe physical envelopes differ (20 × 1.6 mm versus 20 × 2.5 mm). Do not force, stack or infer equivalence from a shared diameter or code pattern.

CR2032Not equivalentThe physical envelopes differ (20 × 1.6 mm versus 20 × 3.2 mm). Do not force, stack or infer equivalence from a shared diameter or code pattern.

CR2320Not equivalentThe physical envelopes differ (20 × 1.6 mm versus 23 × 2 mm). Do not force, stack or infer equivalence from a shared diameter or code pattern.

Supported application context

Devices whose battery compartment or manual specifies CR2016

Application context is limited to the scope stated in Energizer CR2016 Product Datasheet; it is not a device compatibility claim.

The CR2016 code fixes both diameter and height. Nearby CR codes may appear in the same device category but differ physically; verify the complete four-digit designation.

CR2016 is the thinnest supported 20 mm coin cell. CR2025 is 0.9 mm taller and CR2032 is twice its nominal height.

Commonly confused

CR2012 — compare all four decision fields.
CR2025 — compare all four decision fields.
CR2032 — compare all four decision fields.
CR2320 — compare all four decision fields.

What the code means

CR2016 identifies a lithium manganese-dioxide coin cell; the digits encode a nominal diameter and height class, but the cited drawing controls the actual dimensions.

Discharge and drain behaviour

This primary lithium chemistry is intended for low continuous loads with product-specific pulse capability. Capacity figures cannot be compared without matching the load, cut-off voltage and temperature.

Capacity context: Typical product figure near 90 mAh; verify load, cut-off and temperature in a current datasheet.

Substitution guidance

Treat only the listed aliases as exact. A different CR number changes the physical envelope, so do not stack, force or substitute a thinner or thicker coin cell.
