LIR2032 battery replacement and equivalents

EEMB LIR2032 manufacturer example: 3.7 V lithium ion, nominal format 20 × 3.2 mm. Verify the exact manufacturer's specification; this example does not establish every LIR2032's rating or fit. Match the complete specification before treating another marking as a replacement.

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.

Same-size batteries to review carefully

These profiles share the nominal physical envelope. They are not automatically equivalent.

  1. EEMB — LIR2032 rechargeable coin-cell product specifications

    Manufacturer-specific rechargeable LIR2032 nominal voltage and capacity; not a rating for every LIR2032 or device compatibility approval.

  2. EEMB — LIR2032 specification ZJQM-RD-SPC-H0339 (2019-04-19)

    EEMB model voltage and dimensional tolerance on page 3; charger/manual boundary on page 8. Dated manufacturer specification, not a universal LIR rating or a charging guide.

Manufacturer example: EEMB LIR2032

EEMB lists its rechargeable LIR2032 at 3.7 V nominal and 45 mAh. This is not a universal specification for every LIR2032. Its dated specification gives 20.0 mm maximum diameter and 3.2 + 0.2 mm height; the catalog's 20 × 3.2 mm format is a nominal size clue, not a guaranteed fit.

Verify the exact cell manufacturer and model, device documentation and approved charger before use. The nominal voltage is not a charging setting. A matching size does not make this rechargeable cell a replacement for a 3 V CR2032.
