LR44 battery discharge characteristics

FAQs

What is the voltage of LR44 batteries?

• R44 batteries are alkaline button cells that typically provide a nominal voltage of 1.5 volts. They are commonly used in small electronic devices such as watches, calculators, medical devices, and some toys.

Is a LR44 the same as a 357?

The 357 battery, also known as SR44 or AG13, is a silver oxide battery. While both the LR44 and 357 (SR44) batteries have the same physical dimensions, there is a difference in their chemistry and voltage:

• LR44 is an alkaline battery with a nominal voltage of 1.5V.
• SR44 (357) is a silver oxide battery with a nominal voltage of 1.55V.

Due to their similar size and nearly identical voltage, LR44 batteries can often be used as a substitute for SR44/357 batteries in many applications where the slight voltage difference does not matter. However, it's always best to check the device's manual for the recommended battery type.

What batteries can replace LR44?

If you need a replacement for an LR44 battery, you can use the following types, which are physically compatible and have similar voltages:

• AG13
• G13
• A76
• 357 (SR44) (as mentioned above, due to its similar size and slightly higher voltage)

Is LR44 the same as 2032?

• The CR2032 is a lithium coin cell battery with a nominal voltage of 3.0V, which is significantly higher than the LR44's 1.5V. Additionally, the CR2032 has a much larger diameter (20mm compared to the LR44's 11.6mm). Due to these differences in both voltage and size, a CR2032 cannot be used as a direct replacement for an LR44 battery.

• In summary, while LR44 and 357 (SR44) batteries can often be interchanged, an LR44 and a CR2032 are not interchangeable due to differences in both physical size and voltage.

What is the LR44 used for?

• LR44 batteries are known for their small size and stable output and are used in a wide variety of applications. From powering digital thermometers, calculators and laser pointers to being a staple in watches, medical devices and security system panels, LR44 batteries are versatile and often used in small electronic devices that require a compact and reliable power source.
