Answer

CR2025, DL2025, ECR2025 are the supported exact aliases for one 20 × 2.5 mm lithium coin cell. No other family is treated as an automatic replacement.

Top profile · Ø 20 mm

Side profile · 2.5 mm high

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

Format: Lithium coin cell
Dimensions: 20 × 2.5 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 163 mAh; verify load, cut-off and temperature in a current datasheet.
Confidence: High

CR2032Not equivalentThe physical envelopes differ (20 × 2.5 mm versus 20 × 3.2 mm). Do not force, stack or infer equivalence from a shared diameter or code pattern.

CR2016Not equivalentThe physical envelopes differ (20 × 2.5 mm versus 20 × 1.6 mm). Do not force, stack or infer equivalence from a shared diameter or code pattern.

CR2012Not equivalentThe physical envelopes differ (20 × 2.5 mm versus 20 × 1.2 mm). Do not force, stack or infer equivalence from a shared diameter or code pattern.

CR2320Not equivalentThe physical envelopes differ (20 × 2.5 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 CR2025

Application context is limited to the scope stated in Energizer CR2025 Product Datasheet; it is not a device compatibility claim.

The CR2025 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.

CR2025 sits between CR2016 and CR2032 in the 20 mm series. Its 2.5 mm height differs by 0.9 mm from 2016 and 0.7 mm from 2032.

Commonly confused

CR2032 — compare all four decision fields.
CR2016 — compare all four decision fields.
CR2012 — compare all four decision fields.
CR2320 — compare all four decision fields.

What the code means

CR2025 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 163 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.
