What battery is equivalent to LR44?

LR44 is commonly grouped with A76, AG13, 357, and SR44-size button cells. Check chemistry and voltage: alkaline LR44/A76 is 1.5V, while silver-oxide 357/SR44 is often 1.55V and usually lasts longer in watches and instruments.

Are CR2032 and CR2025 interchangeable?

CR2032 and CR2025 have the same 20 mm diameter and 3V lithium chemistry, but CR2032 is 3.2 mm thick while CR2025 is 2.5 mm thick. A device may not hold the thinner cell tightly or close around the thicker cell.

How do coin cell battery numbers work?

Many lithium coin cells use size codes where the first two digits are diameter in millimeters and the last two digits are thickness in tenths of a millimeter. For example, CR2032 is about 20 mm wide and 3.2 mm thick.

Best match LR44 / AG13 / A76

11.6 mm × 5.4 mm, alkaline 1.5V button cell.

Voltage 1.5V

Size 11.6 × 5.4 mm

LR44 equivalents include A76, AG13, L1154, and PX76A. Silver-oxide 357/SR44 cells are the same size but a slightly different chemistry.

Equivalent names and close matches

Use the exact same size and suitable voltage for best fit.

How to choose the right replacement

Match the printed code first, then compare diameter, height, voltage, and chemistry. The same physical size can appear under several names because manufacturers and chemistries use different prefixes.

Lithium CR cells are usually 3V. Alkaline LR and AG cells are usually 1.5V. Silver-oxide SR watch cells are usually 1.55V and often keep a steadier voltage for watches, calipers, thermometers, and small instruments.

Quick code clues

CR2032 means about 20 mm diameter and 3.2 mm height.
LR44, AG13, A76 are common names for an 11.6 × 5.4 mm alkaline button cell.
SR626SW and 377 are common watch-battery equivalents.
When thickness differs, the cell may fit loosely or prevent the battery door from closing.

Coin cell battery FAQ

Can I replace LR44 with 357?

Often, yes, if the device accepts the same 11.6 × 5.4 mm size. LR44 is alkaline 1.5V; 357/SR44 is silver oxide around 1.55V and can last longer in steady-drain devices. Avoid swapping chemistry when the device manual requires one type.

What is the difference between CR2032, CR2025, and CR2016?

They are all 20 mm diameter 3V lithium cells, but thickness changes: CR2032 is 3.2 mm, CR2025 is 2.5 mm, and CR2016 is 1.6 mm. Thickness affects contact pressure and capacity.

Are AG and LR battery numbers the same?

AG numbers are commonly used retail labels for alkaline button cells, while LR numbers are IEC-style alkaline labels. Many map to the same physical size, but it is still smart to check the dimensions and voltage.
