Can I replace LR44 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 LR44. Always verify voltage, chemistry and the requirements printed in your device manual before fitting a replacement.
LR44 questions
What batteries are equivalent to the LR44?
The LR44 is sold as AG13, A76, L1154, 157. All of these describe the same 11.6 × 5.4 mm alkaline cell at 1.5 V.
Can I use a SR44 instead of a LR44?
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 LR44 last?
A LR44 holds a typical 110–130 mAh. Real runtime depends entirely on how much current your device draws and whether it is used continuously.
Is the LR44 rechargeable?
No. The LR44 is a single-use cell and should not be recharged.
