Answer

CR1616, DL1616, ECR1616, KECR1616 are the supported exact aliases for one 16 × 1.6 mm lithium coin cell. No other family is treated as an automatic replacement.

Top profile · Ø 16 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: 16 × 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 55 mAh; verify load, cut-off and temperature in a current datasheet.
Confidence: High

CR1620Not equivalentThe physical envelopes differ (16 × 1.6 mm versus 16 × 2 mm). Do not force, stack or infer equivalence from a shared diameter or code pattern.

CR1632Not equivalentThe physical envelopes differ (16 × 1.6 mm versus 16 × 3.2 mm). Do not force, stack or infer equivalence from a shared diameter or code pattern.

CR1216Not equivalentThe physical envelopes differ (16 × 1.6 mm versus 12.5 × 1.6 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 CR1616

Application context is limited to the scope stated in Energizer CR1616 Product Datasheet; it is not a device compatibility claim.

The CR1616 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.

CR1616 and CR2016 share a 1.6 mm height but differ by 4 mm in diameter. The last two digits are therefore not an identifier on their own.

Commonly confused

CR1620 — compare all four decision fields.
CR1632 — compare all four decision fields.
CR1216 — compare all four decision fields.
CR1220 — compare all four decision fields.

What the code means

CR1616 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 55 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.
