CR2032 vs CR2025 vs CR2016 — Size & Capacity Comparison
Equivalent & Cross-Reference
These references are electrically compatible. Always match size and voltage before replacing.
Common Applications
CR2016 is used every day in these classes of devices — the cell is matched to each duty below, and every pack is tested against the appliance profile before dispatch.
Key fobs & car remotes
Car key fobs and remote-entry keychains: the cell sits behind the removable rubber cap. A fresh cell restores the push-to-start response and the range that fade as voltage drops.
Motherboard CMOS
BIOS backup cell on desktop and server motherboards. When it fades, the system forgets the clock and BIOS settings after power-off — replacement takes a minute and restores a clean startup.
Wholesale Battery Supplier — Factory Direct
Buy in Bulk: CR2016 available for distribution in bulk packs, 5-pcs child-resistant cards or custom retail packaging under your brand.
