Battery cells for buttons power numerous tiny devices, ranging from watches to toys for children. Most commonly used are the AG13, LR44 and 357 batteries. But can they be interchangeable? If you've ever wondered which to choose when your device has run out of juice This guide will to clarify the different characteristics as well as their similarities and applications.
What Are LR44, AG13, and 357 Batteries?
All three batteries are 1.5V buttons however, they are from different brands and differ in their performance. Here's a quick breakdown:
- LR44 The most widely known name for an alkaline battery utilized in watches, calculators and other small electronic devices.
- AG13 The AG13 is basically similar to LR44 however it is often labeled different by different brands such as Energizer and Panasonic.
- 357 (also called SR44) Silver oxide battery that offers an extended life and more steady voltage output. Typically employed in high-end devices such as medical thermometers and watches of high-end.

Are LR44, AG13, and 357 Batteries Interchangeable?
In the majority of cases, yes--these batteries are able to be used in conjunction with each other because they have the same
- Voltage (1.5V) - Ensures compatible power delivery.
- Format (11.6mm diameter in height 5.4mm tall) - Fits the identical compartments for batteries.

When to Choose LR44 or AG13
They are economical and can be used in:
- Toys (e.g. remote-controlled vehicles LED gadgets, remote-controlled cars)
- Calculators
- Simple digital watch
Because they're chemically equivalent and chemically identical, you can make use of an AG13 instead or an LR44 without any issues.
When to Opt for a 357/SR44 Battery
357 (SR44) silver oxide battery is ideal for devices that require: 357 (SR44) silver oxide battery is perfect for gadgets that require:
- Longer lifespan It can last at least 50 more than the alkaline versions.
- Variable voltage Stable voltage Crucial for precise instruments such as glucose meters, or watches with luxury (e.g., Casio, Seiko).
If your device was originally an SR44 replace it with an AG13 or LR44 AG13 might work for a while but performance might decrease more quickly.
Where to Buy These Batteries
There are LR44 3, AG13 and 357 batteries at:
- Electronics shops (Best Buy), Fry's Electronics)
- Online retailers (Amazon, Walmart)
- Pharmacies in the local area (CVS, Walgreens)
The cost of buying in bulk is usually less expensive, particularly for commonly used batteries such as the LR44.
How to Replace a Button Cell Battery
The process of swapping these batteries is easy:
- The compartment must be opened by using an appropriate screwdriver.
- Get rid of the old battery Note that the battery's orientation (+/-).
- Add the new HTML0 Make sure you match the direction of the polarity.
- Make sure the gadget is tested - Make sure it is powered correctly.
Final Verdict: Which One Should You Use?
- for toys and basic electronic devices For basic electronics and toys either LR44 or AG13 (affordable and easy to locate).
- for watches and medical equipment (such as 357/SR44 (longer-lasting and more stable).
