The LR44 and 357 batteries are both small, button-shaped cells commonly used in a variety of small electronic devices. Here's a comparison between the two:
LR44 Battery
- Type: Alkaline
- Voltage: 1.5 volts
- Size: 11.6 mm diameter × 5.4 mm height
- Common Equivalents: AG13, A76, L1154, 303, RW42, and SR44
357 Battery
- Type: Silver oxide
- Voltage: 1.55 volts
- Size: 11.6 mm diameter × 5.4 mm height
- Common Equivalents: SR44, SG13, SR44SW, and SR1154
Comparison
-
Chemistry: The LR44 battery uses alkaline chemistry, while the 357 battery uses silver oxide chemistry. Silver oxide batteries typically have a higher energy density and are often used in precision instruments and medical devices.
-
Voltage: The LR44 battery has a nominal voltage of 1.5 volts, while the 357 battery has a nominal voltage of 1.55 volts.
-
Applications: LR44 batteries are commonly used in small electronic devices such as watches, calculators, and toys. The 357 battery is also used in similar devices but is especially common in precision instruments, medical devices, and applications where a stable voltage and longer shelf life are crucial.
The Difference in Specifications
| lR44 | 357 | |
| Battery type | Alkaline Manganese Batteries | Silver Oxide |
| Nominal Voltage | 1.5V | 1.55V |
| Nominal Capacity | 120mAh | 150 mAh |
| Operating Temperature Range | -10℃ to 60℃ | |
| Diameter (inch) | 0.457inch | |
| Diameter (mm) | 11.6mm | 11.6mm |
| Height (inch) | 0.213inch | 0.213inch |
| Height (mm) | 5.4mm | 5.4mm |
| IEC (JIS) | LR44 | |
| Mass (oz) | 0.0705oz | |
| Mass (g) | 2g | 2.3g |
Interchangeability
These two batteries are interchangeable in many devices. The slightly higher voltage of the 357 battery can sometimes affect the performance of devices designed for the lower voltage LR44, so it's always best to check the device's specifications and consult the user manual if possible. In many cases, however, the voltage difference is small enough that they can be used interchangeably.
When replacing batteries in a device, it's important to ensure that the replacement battery matches the voltage and size requirements. Always check the device's documentation or consult an expert if you have any doubts about the appropriate replacement.
