Equivalent Batteries: The 357 battery has a few equivalent designations, including:

  • SR44 (Common alternative naming)
  • SR44W (Alternate designation)
  • SR1154 (IEC designation)
  • SG13 (Other alternative designation)



These equivalents represent the same battery size and voltage, but may have different manufacturer codes or regional naming conventions.

Specifications: The following are typical specifications for a 357 battery (SR44):

  • Nominal Voltage: 1.55 volts
  • Chemistry: The 357 battery typically utilizes a silver oxide chemistry (Silver Oxide - Ag2O). This chemistry provides a stable voltage output over the battery's lifespan.
  • Capacity: The capacity of a 357 battery is typically around 150-200mAh.
  • Dimensions: The dimensions of a 357 battery are approximately 11.6mm in diameter and 5.4mm in height.

Replacements: When selecting a replacement for a 357 (SR44) battery, it's important to consider the physical dimensions, voltage, and capacity requirements of the device. Some possible replacements include:

  1. SR44W: This is essentially the same battery with a different naming convention.
  2. LR44: The LR44 battery is an alkaline equivalent to the 357 (SR44) battery. It provides a slightly lower voltage (1.5V) compared to SR44's 1.55V, but can often be used as a replacement in many devices.
  3. SR43: This battery may also work as a substitute in devices that accept 357 batteries, but users should check the device compatibility before using it.

As always, ensure to consult the device's specifications or documentation to determine the exact battery requirements. Using batteries from reputable manufacturers can help ensure quality and performance in your devices.
