LR44 Battery: Equivalent, Specifications and Replacements


LR44 batteries, also known as AG13 or L1154, are small, cylindrical alkaline cells commonly used in small electronic devices. Here are some details about the LR44 battery, its equivalents, specifications, and potential replacements:

LR44 Battery

Equivalent Batteries:

The LR44 battery has several equivalents. The most common equivalents include:

  • AG13
  • L1154
  • 357
  • A76
  • PX76A
  • 303
  • RW42
  • SR44


The LR44 battery typically has the following specifications:

  • Chemistry: Alkaline
  • Voltage: 1.5 volts
  • Capacity: Typically around 150-170 mAh
  • Dimensions: 11.6 mm diameter × 5.4 mm height
  • Shape: Button/cylindrical

Common Uses:

LR44 batteries are commonly used in small electronic devices such as:

  • Watches
  • Calculators
  • Digital thermometers
  • Laser pointers
  • Keychain lights
  • Small toys and games
  • Some medical devices
  • Hearing aids


When replacing LR44 batteries, it's essential to ensure the equivalent battery has the same voltage rating and dimensions to fit in the device. Common replacement options include:

  • SR44 (silver oxide equivalent with a slightly different voltage curve)
  • 357/303 (often silver oxide, can have different voltage curve but still compatible in many devices)
  • A76/AG13
  • CR44 (lithium equivalent with a higher initial voltage but a flatter discharge curve)

Buying Considerations:

When purchasing replacements, ensure they are from reputable manufacturers to guarantee quality and performance. Also, consider looking for environmentally friendly options such as rechargeable equivalents or proper disposal of expended batteries, as they contain potentially hazardous materials.

It's important to note that using a different chemistry or voltage rating which doesn't match the requirements of the device can lead to improper function or damage. Always refer to the device manual or consult an expert if you are unsure about the proper replacement for your LR44 battery.
