|---|---|---|
| CR2450 | 24.5 × 5 mm3 V | This page. |
| CR2430 | 24.5 × 3 mm3 V | Same 24.5 mm width, but 3 mm thick. It may fit loosely and holds about half the charge. |

| CR2032 | 20 × 3.2 mm3 V | Smaller (20 mm). It won't stay in place. |
Good to know

- Found in smart home sensors, some car keys and kitchen scales that need more than a CR2032 can hold.
- Keep coin cells away from children. A swallowed coin cell can burn through the throat within hours, so treat it as an emergency and get help straight away.

Battery Inventory for iPhone and iPad
Never look up the CR2450 again.
Battery Inventory remembers which battery every device in your home takes, reminds you when one is due, and counts the spares in your drawer, so you buy the right cell before the old one dies. The finder in the app knows every code on this page. Search any of them, or point the camera at a coin cell to read it.
- Battery change reminders, free
- Monthly smoke and CO alarm test reminders
- A spares drawer and shopping list
- Cordless tool packs and chargers too
No account needed. Smoke and CO alarm features are reminders only: the app can't see or test your alarms.
