“017 and 019 Battery” are both acronyms, but they represent different concepts:
Below are the main Differences between 017 and 019 Battery.
I assume that you are referring to button cell batteries, specifically the CR017 and CR019.
The main difference between the CR017 and CR019 batteries is their size. The CR017 battery has a diameter of 5.8mm and a height of 1.7mm, while the CR019 battery has a diameter of 6.8mm and a height of 1.9mm.
In addition to their size difference, the CR019 also has a slightly higher capacity compared to the CR017. The CR019 has a capacity of 28mAh, while the CR017 has a capacity of 20mAh. This means that the CR019 battery can provide slightly more power before it needs to be replaced.
It’s important to note that these batteries are not interchangeable, as they have different sizes and voltage ratings. It’s important to check the device’s manual or specifications to determine the correct battery type and size to use
