Commonly confused with

One CR1/3N can replace two LR44 only when a device manual lists both (e.g. Minolta X-700) — not a general drop-in

Device-specific caveats

From manufacturer-backed notes on devices that use LR44 — not generic advice.

Keep button cells away from children.
Do not use 1.35V mercury MR44 / PX625-class cells; the manual forbids mercury lookalikes.
