Differences Between LR44 and L1154 Battery
LR44 and L1154 batteries are both common types of alkaline button cell batteries, often used interchangeably in various electronic devices. However, they do have some distinctions worth noting:
- Chemical Composition:
The LR44 battery typically uses a combination of zinc and silver oxide, whereas the L1154 is made from alkaline manganese dioxide with lithium as the negative electrode12. This difference can affect performance characteristics such as discharge rates and longevity.
- Dimensions:
While both batteries share the same diameter (11.6 mm), the height differs slightly: LR44 is approximately 5.4 mm tall, while L1154 is about 4.2 mm tall24. This height difference may impact compatibility with certain devices.
- Capacity Variance:
The capacity of LR44 can range from 100 to 175 mAh, depending on the manufacturer and specific type, while L1154 generally has a capacity around 150 mAh35. This can influence how long each battery lasts under similar usage conditions.
- Interchangeability:
Both batteries operate at the same voltage and are often marketed with overlapping names (e.g., AG13). They can generally be used interchangeably in many devices; however, it’s essential to ensure that the height difference does not affect fitting in specific applications.
In summary, while LR44 and L1154 batteries are similar in voltage and application, they differ in chemical composition, dimensions, and capacity. Understanding these differences is crucial for selecting the appropriate battery for your device to ensure optimal performance and compatibility.
