These codes describe the same physical cell as the 357.
Can I replace 357 with…
Cells that fit the same space but differ in chemistry or voltage.
Check before you swap. Batteries with similar dimensions are not always interchangeable with the 357. Always verify voltage, chemistry and the requirements printed in your device manual before fitting a replacement.
357 questions
What batteries are equivalent to the 357?
The 357 is sold as SR44, SR44W, V357. All of these describe the same 11.6 × 5.4 mm silver oxide cell at 1.55 V.
Can I use a LR44 instead of a 357?
In many low-drain devices, yes — the sizes match. Check the voltage and chemistry against your device's requirement first, because a small voltage difference can matter in calibrated equipment.
How long does a 357 last?
A 357 holds a typical 150–190 mAh. Real runtime depends entirely on how much current your device draws and whether it is used continuously.
Is the 357 rechargeable?
No. The 357 is a single-use cell and should not be recharged.
