SR41 and LR41 batteries are button/coin cell batteries that are commonly found in digital thermometers, wristwatches, toys, small LED flashlights, wearable electronics, remote controls, and other similar products.
These batteries come in a variety of chemistries with similar, but not identical, discharge characteristics, and are frequently labeled differently by their makers, causing some user confusion.
The SR41 and LR41 batteries have the same physical dimensions (D x H) of 7.9 x 3.6 mm (0.311 x 0.142 inches), with the following shared features:
| Chemistry | Alkaline | Silver-Oxide | Zinc Air |
| Nominal Voltage | 1.5V | 1.55V | 1.4 - 1.45V |
| Cutoff Voltage | 1.0V | 1.2V | 1.1V |
| Notes | Voltage drops over time | Very constant voltage | Slightly lower voltage, large capacity; mostly used as hearing aid batteries |
| Typical Labels | LR41, LR736, AG3 | SR41 , SR736, SR736PW, SR736SW, SG3, AG3, 192, 384, 392 | 312, ZA312, Brown Tab, PR41, 7002ZD |
