Upgrade or downgrade
Same size, different chemistry. Read the verdict before you buy.
| Cell | Chemistry | Voltage | Verdict |
|---|---|---|---|
| LR1130 | alkaline | 1.5 V | Downgrade Works, but runs out sooner. Avoid in watches and medical devices. |
Similar size, check the fit
Same diameter, different thickness. These are not drop-in replacements.
| Cell | Size | Verdict |
|---|---|---|
| SR1116SW | 11.6 × 1.65 mm | Same 11.6 mm diameter, but 1.65 mm tall instead of 3.1 mm. Only if the holder fits; thinner cells can lose contact. |
| SR1120SW | 11.6 × 2.1 mm | Same 11.6 mm diameter, but 2.1 mm tall instead of 3.1 mm. Only if the holder fits; thinner cells can lose contact. |
| SR1126 | 11.6 × 2.6 mm | Same 11.6 mm diameter, but 2.6 mm tall instead of 3.1 mm. Only if the holder fits; thinner cells can lose contact. |
| SR42 | 11.6 × 3.6 mm | Same 11.6 mm diameter, but 3.6 mm tall instead of 3.1 mm. Only if the holder fits; thinner cells can lose contact. |
| SR43 | 11.6 × 4.2 mm | Same 11.6 mm diameter, but 4.2 mm tall instead of 3.1 mm. Only if the holder fits; thinner cells can lose contact. |
| SR44 | 11.6 × 5.4 mm | Same 11.6 mm diameter, but 5.4 mm tall instead of 3.1 mm. Only if the holder fits; thinner cells can lose contact. |
Low drain or high drain
SR1130SW is sold under two numbers for the same case size. Manufacturers mark low-drain cells SW and high-drain cells W, which records what the cell is built to deliver rather than how big it is.
- Low drain (SW): 390
- A steady trickle of current: a quartz watch with hands, a thermometer, a key fob.
- High drain (W): 389
- Short bursts of heavier current: a watch with a backlight, an alarm or a chronograph.
Both are 1.55 V and both fit the same holder, so either will run the device. The matched one lasts longer.
