CR2032 Lithium Button Cell 3V — 205mAh Coin Battery

CR2032 is the highest-volume lithium coin cell in the world and the one where dimensional accuracy is checked by the end user, not by a lab: the cell is retained by spring contacts, so a can that is a fraction of a millimetre off causes intermittent contact and a warranty claim. This cell is 20 mm × 3.2 mm with 205mAh of lithium manganese dioxide capacity and a stable 3V plateau across the discharge.

Key features

• 205mAh nominal capacity with a stable 3V output for clock and memory backup duty.
• Tight dimensional tolerance to IEC 60086 so the cell seats correctly in spring holders.
• Low self-discharge chemistry — 3-year shelf life standard, 5-year option available.
• Trays for production lines or blister cards for retail, with OEM printing on the can.
• CE, SGS, RoHS, REACH and UN38.3 documentation for air and sea freight.

Typical applications

Car key fobs and remote entry, Digital scales and thermometers, CMOS/BIOS clock backup on motherboards, Watches and small clocks, LED lights and novelty electronics.

Packing and ordering

Bulk trays for device assembly or 5-piece blister cards for retail, packed 100 per inner box and 5,000 per carton (39 × 29 × 30 cm, 21.9 kg gross).

Who buys this model

For electronics manufacturers, accessory brands, watch and key-fob retailers and distributors that buy CR2032 in production volumes.
