When shopping for button batteries, many consumers encounter two commonly confused models: LR44 battery and 357 battery. Despite looking nearly identical, they serve slightly different purposes due to their chemical composition and voltage stability. This guide breaks down everything you need to know so you can select the best battery for your device.
The LR44 battery is a widely used alkaline button cell. Its affordability, wide availability, and versatility make it one of the most popular choices for many everyday devices.
The 357 battery, on the other hand, belongs to the silver-oxide family. This chemistry allows it to maintain a much steadier voltage until it is nearly depleted, making it ideal for precision instruments.
Though their internal chemistry differs, both batteries share identical physical dimensions:
Feature | LR44 | 357 |
---|---|---|
Diameter | 11.6 mm | 11.6 mm |
Height | 5.4 mm | 5.4 mm |
Shape | Button Cell | Button Cell |
Alternate Names:
LR44: AG13, A76, L1154
357: SR44, SR44W, SR44SW
Feature | LR44 (Alkaline) | 357 (Silver-oxide) |
---|---|---|
Voltage | 1.5V | 1.55V |
Voltage Stability | Declines steadily | Holds stable |
Capacity | 110–150 mAh | 150–200 mAh |
Shelf Life | 3–5 years | 5–10 years |
Price | Lower | Higher |
Are LR44 and 357 interchangeable?
Physically, yes. But performance may differ based on the device. Low-drain devices can handle either; precision devices often need 357.
Can I replace a 357 battery with LR44?
For some non-sensitive gadgets, yes. For devices that require voltage stability, it's not recommended.
Why is the 357 battery more expensive?
Silver-oxide technology is more costly but offers better stability, longer life, and higher capacity.
Can I mix battery types?
No. Mixing alkaline and silver-oxide cells may lead to leakage, reduced performance, or device malfunction.
How to store these batteries?
Store in a dry, cool place away from humidity and heat to maximize shelf life.
