Frequently Asked Questions

Is SR44 the same as 357?

Yes, the SR44 is equivalent to the 357 in button cell batteries. They are interchangeable, sharing the same physical size and voltage specs. So, you can use an SR44 battery as a direct replacement for a 357 battery, and vice versa.

Can I Use SR44 instead of LR44?

Yes, in many cases, you can use SR44 batteries as substitutes for LR44 batteries, and the other way around, since they share the same size and shape. Both are commonly used in small electronic devices like watches and calculators.

What Does LR Stand For in Batteries?

In battery terms, LR usually refers to an Alkaline battery.

At What Voltage is an LR44 Battery Dead?

An LR44 battery is considered dead at around 0.9 to 1.0 volts.

Can a 675 Battery Replace an LR44?

No, the LR44 and 675 batteries are not interchangeable due to differences in size and voltage. The LR44 is smaller and commonly used in watches and calculators, while the 675 is larger and typically used in hearing aids.

Is LR44 the Same as 386?

While the LR44 and 386 batteries are similar in size, they differ in chemistry. The LR44 usually uses alkaline chemistry, while the 386 (and its equivalents) typically uses silver oxide chemistry. Also, the LR44 has a nominal voltage of 1.5V, whereas the 386 usually has a nominal voltage of 1.55V.
