Frequently Asked Questions

Is LR41 same as LR44?

LR41 is also known as AG3 384 392 192 LR736 L736 GP192 and V36A button battery. LR44 is also known as AG13 357 L1154 A76 PX76A 303 D303 and D357 button battery.

What battery can replace LR41?

Direct replacements for LR41 would be 192, 92A, LR736, and AG3. These batteries are exact equivalents for the LR41 battery, the only difference being the name.

Can I use 377 instead of LR41?

A 377 battery is a Silver Oxide type. They will both fit the application, but the Silver Oxide type will last longer.

What are LR41 batteries for?

LR41 batteries are most commonly used in thermometers, as well as other common electronic devices including laser pointers and some watches.

What are LR41 batteries for?

I checked reference guides and found that the lr41 is equivalent to 392, and lr44 is equivalent to the 357 button batteries.
