Can I use another battery instead of an LR754?
| Battery | Size | Volts | Works? | Why |
|---|---|---|---|---|
| SR48 | 7.9 mm × 5.4 mm | 1.55 V | Yes | Same size; silver oxide lasts longer (an upgrade). |
| LR41 | 7.9 mm × 3.6 mm | 1.5 V | Short-term | 1.8 mm thinner: may sit loose; fine short-term. |
| Size 312 | 7.9 mm × 3.6 mm | 1.45 V | No | Zinc-air cells need air holes; not for sealed devices. |
| SR41 | 7.9 mm × 3.6 mm | 1.55 V | Short-term | 1.8 mm thinner: may sit loose; fine short-term. |
| Size 13 | 7.9 mm × 5.4 mm | 1.45 V | No | Zinc-air cells need air holes; not for sealed devices. |
