Common Applications

CR1212 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.
