The LR44 battery is a small button cell battery of alkaline-manganese composition with a nominal voltage of 1.5 volts. The LR44 battery is identical in size to silver oxide button cells such as SR44, SR44SW, 303, 357, but different in chemistry. There are several batteries that are equivalent to the LR44 battery, including:

• A76
• AG13
• L1154
• LR1154
• 157

These batteries are exact equivalents for the LR44 battery, with the only difference being the name. They can all be interchanged. Other batteries that are the same size and dimensions as the LR44 battery but are not exact equivalents or direct replacements as they are constructed of different chemistries offering different performances.

It is important to note that while some batteries have the same dimensions and voltage as the LR44 battery, there may be some differences between these batteries that could affect their compatibility with specific devices.
