What are the dimensional tolerances of the LIR2032 coin cell case and why are they critical for assembly?
The upper cover inner diameter is 16.45±0.05 mm, outer diameter 19.32±0.04 mm, and height 2.80±0.04 mm. The lower case outer diameter is 19.95+0.05/-0.03 mm, inner diameter 19.90+0.04/-0.02 mm, and height 2.86±0.04 mm. These tight tolerances ensure a precise fit between the matched case parts, which is essential for consistent sealing and preventing electrolyte leakage in coin cell assembly.
Is this coin cell case specifically designed for LIR2032 batteries or can it be used for other 20 mm coin cell types?
This case is designed for the LIR2032 form factor, with a finished size of 20 mm diameter x 3.2 mm height. The dimensions match the standard LIR2032 rechargeable coin cell. While it can be used for other 20 mm-class coin cells with similar dimensions, the matched case components are optimized for LIR2032 assembly. Users should verify compatibility with their specific electrode and separator stack thickness.
This LIR2032 coin cell case set provides matched 304 stainless steel upper and lower case components with a black polypropylene gasket in a 20 mm × 3.2 mm format, with explicit dimensional tolerances for assembly. Buyers must verify the required case dimensions and gasket configuration before ordering.
Positive
- Matched 304 SS case set with gasket: Positive and negative case parts are supplied as a matched set with a black polypropylene gasket, so all case components needed for a 20 mm-class coin cell assembly are provided together.
- Explicit dimensional tolerances for assembly: The upper cover and lower case are specified with individual dimensional tolerances, giving a defined mechanical fit envelope for reproducible coin cell construction.
Trade-offs
- Confirm dimensions and gasket before ordering: The product page requires buyers to confirm the required case dimensions and black gasket configuration before ordering, since this SKU is a fixed 20 × 3.2 mm polypropylene-gasket configuration.
- Polypropylene gasket material is fixed: The only listed gasket for this case is black polypropylene; applications requiring a PTFE gasket are directed to a separate case product, so gasket-material selection is not interchangeable on this SKU.
