Looking for a CR2032 replacement? Confirm the thickness before buying - 3.2 mm differs from the 2.5 mm CR2025 and the 1.6 mm CR2016, and a mismatch means a loose cell, not a failed device.
If you compare CR2032 vs CR2025 pricing, remember the capacity difference: the CR2032 delivers about 220 mAh versus 165 mAh. For bulk and private label buyers we quote per carton, with the child-resistant card format included.

Packing quantities are standard; other formats on request.
CR2032 vs CR2025 vs CR2016
All three are 20 mm lithium cells; the difference is thickness — 3.2 mm, 2.5 mm and 1.6 mm. A CR2032 will not seat in a CR2016 socket, and a thinner cell may work intermittently in a holder designed for 3.1 mm. Check the thickness stamped on the device before replacing.
Wholesale & Custom Supply
Buy CR2032 in bulk directly from the factory: wholesale price on 50 cartons and up, OEM label and packaging options, and UL / UN38.3 transport documents issued with every export order.

FAQ
What is a CR2032 battery?
A 20 mm diameter, 3.2 mm thick 3V lithium coin cell with about 220 mAh typical capacity.
How long does a CR2032 last?
In a car key fob 2–3 years; in a motherboard CMOS 5–10 years while the device is plugged in.
What is a CR2032 compatible with?
5004LC, ECR2032, KCR2032 and DL2032 — same size and voltage, interchangeable.
Does CR2032 fit in a car key fob?
Yes. Most car key fobs (Toyota, Honda, Nissan, Ford) use CR2032 or CR2025.
Can a CR2032 be recharged?
No. Standard CR2032 is primary lithium — replace rather than recharge.
