What is an LR44 Battery?
An
LR44 battery is a small, round, coin-shaped alkaline battery commonly used in various small electronics, such as watches, calculators, laser pointers, and medical devices. It is known for its compact size, 1.5V power output, and long shelf life. This type of battery is widely available and affordable, making it a popular choice for devices that require reliable power in a small form factor. The
LR44 battery voltage is typically 1.5 volts.
LR44 Battery Features
The
LR44 battery offers several key features:
- Voltage: 1.5V (nominal)
- Capacity: 110-130 mAh
- Chemistry: Alkaline
- Size: Diameter of 11.6mm, thickness of 5.4mm
- Shelf Life: Can last up to 5 years when stored properly
- Common Uses: Watches, laser pointers, thermometers, toys, calculators
The
LR44 battery voltage and compact design make it ideal for low-drain devices, offering long-lasting power without frequent replacements.
Which Battery is Equivalent to LR44?
Several batteries are equivalent to the
LR44 battery, meaning they can be used as replacements in devices that require LR44. Common
lr44 battery equivalent options include:
- 357 Battery: Often used interchangeably with LR44. The LR44 battery equivalent 357 is a silver oxide version, offering slightly better performance in some devices.
- CR2032 Battery: This is a larger 3V battery but can sometimes be used as an alternative in devices where size and voltage differences are not an issue. This is known as an LR44 battery equivalent CR2032.
- 675 Battery: Sometimes used in hearing aids, the LR44 battery equivalent 675 is also an option in specific cases, though it offers slightly different characteristics.
Is an LR44 Battery the Same as a 357?
While both the
LR44 battery and the
357 battery are often used in similar devices, they are not exactly the same. The
LR44 battery equivalent 357 offers different chemistries:
- LR44: Alkaline, 1.5V
- 357: Silver oxide, 1.55V
The silver oxide version (357) has a more stable voltage throughout its lifespan, making it a better option for high-precision devices. However, in most cases, they are interchangeable due to the small voltage difference.
How Long Does an LR44 Battery Last?
The lifespan of an
LR44 battery depends on the device it’s used in and the specific energy demands of that device. Generally, the battery can last for:
- Low-drain devices: Up to 2-3 years
- High-drain devices: Several months to a year
On average, an
LR44 battery offers about 110-130 mAh of capacity. Regular use in small devices can give you long-lasting power, but it's important to note that the exact duration will vary based on the device and usage patterns.
