Due to these characteristics, the 357 battery remains a reliable, versatile, and affordable power source for an array of electronic devices, combining affordability with high performance.

LR44 vs 357 Batteries: Main Differences

Chemistry and Voltage

Alkaline LR44 and silver oxide 357 batteries are both button cell batteries. Voltage stability and discharge rates are affected by the battery's chemistry. As a comparison, the LR44 battery usually provides a nominal voltage of 1.5V, while the 357 battery provides a marginally higher voltage of 1.55V. Devices that require precise energy output can be affected by this voltage difference. Especially in applications where reliability is crucial, the 357 battery's consistent discharge curve may benefit devices that are more sensitive to voltage variations.

Shelf Life and Storage

Shelf life is generally better for 357 batteries than LR44 batteries. 357 batteries retain their charge longer than other batteries due to the silver oxide chemistry they use, often up to five years when they are stored correctly. A LR44 battery, on the other hand, typically has a shelf life of three to four years. With this difference, users who prefer to keep spare batteries on hand without worrying about them losing their charge will prefer the 357 battery. A 357 battery's longer shelf life is an added convenience and assurance for devices that may sit unused for extended periods.

Cost and Availability

The difference in manufacturing processes and materials makes LR44 batteries more affordable than 357 batteries in terms of cost. A wide range of retailers and online marketplaces offer the LR44 battery. Silver oxide, which is generally considered a premium battery chemistry, is used in the 357 battery, which is also widely available. In particular, consumers seeking budget-friendly options may be influenced by this price difference. Users find the 357 battery's benefits to be worth the additional cost for applications that require higher reliability and longer shelf life.

Discharge Characteristics

Batteries LR44 and 357 exhibit significantly different discharge characteristics. Battery performance may be reduced during a charge or discharge cycle with the LR44 battery due to its gradual voltage drop. A 357 battery, on the other hand, is capable of maintaining a higher voltage output for a longer period before degradation occurs, which is imperative for devices that require consistent performance. In high-precision devices such as medical instruments and some electronics, where accurate readings and reliable operation are critical, a stable voltage is especially important.

Applications

LR44 Battery

Calculators

Scientific calculators, financial calculators, and basic calculators commonly use LR44 batteries. To perform accurate calculations, these calculators need a compact power source with a consistent voltage. Its small size makes it the ideal choice for portable devices, as it can easily fit into the slim design of calculators. Furthermore, even when calculators are not regularly used, LR44 batteries will remain functional for a long time.
