Common Applications
CR1220 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.
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.
Remote controls
TV, set-top, ceiling-fan and gate remotes. Low-drain duty: one cell usually lasts 1–3 years in a remote used several times a day.
Small electronics
Small electronics — blood-pressure monitors, LED candles, hospitality remotes. The cell fits the board layout of most portable devices.
