CR2025: what to know
- It is 0.7 mm thinner than a CR2032, so a CR2032 will not fit a holder made for a CR2025.
- Going the other way, a CR2025 often works in a CR2032 holder because the spring contact takes up the gap, but it can lose contact when bumped.

| CR2016 | 20 mm × 1.6 mm | 3 V | Short-term | 0.9 mm thinner: may sit loose; fine short-term. |
| CR2032 | 20 mm × 3.2 mm | 3 V | No | 0.7 mm thicker: will not fit. |
| LIR2032 | 20 mm × 3.2 mm | 3.7 V | No | Rechargeable 3.7 V cell (4.2 V when full): can damage a 3 V device. |

20 mm coin cells are the size children swallow most; one can burn the throat in two hours. Keep spares sealed and battery doors taped.
