Replacement decision

Resolve the original marking to this profile, then confirm nominal voltage, chemistry, dimensions, polarity and any drain or terminal suffix. Capacity alone does not establish interchangeability.

Equivalence and fit table

These rows use the catalog’s source-backed profile data and compatibility rules. An exact alias resolves to the same profile; every other row is a comparison to review, not an automatic substitute.

Fit guidance for CR1025

The catalog resolves CR1025 and DL1025 and ECR1025 to the CR1025 profile. Reviewed comparison rows are CR2025: not equivalent. Use the Fit decision column and the device manual before selecting a non-exact row.

Verify before replacing CR1025

  1. Read the complete marking and check whether it resolves to CR1025 or to another profile.
  2. Compare the 3 V, Lithium manganese dioxide, and 10 × 2.5 mm values shown above with the device manual.
  3. For a non-exact row, follow its generated fit decision and confirm polarity, terminals, drain behavior, or charging requirements before installation.
