What is a Coin Cell Battery? The Difference Between Lithium, Alkaline, and Silver Oxide Coin Cell Batteries
Coin cell batteries come in three main types: lithium, alkaline, and silver oxide. They’re all designed for small electronics like key fobs and calculators, but each one comes equipped with different features.
- Lithium: These batteries are ideal for devices that require extended battery lifespan. Wristwatches are a good example of this. Manganese dioxide provides the positive electrode with lithium as the negative electrode. As an added benefit, lithium batteries perform well in low temperatures.
- Alkaline: These batteries are typically less expensive and provide less energy than lithium and silver oxide batteries. The charge is created with manganese dioxide as a positive electrode and zinc as a negative electrode.
- Silver Oxide: Silver oxide batteries may have a stable voltage output before suddenly dropping off at the end of their life. Silver oxide is used as a positive electrode with zinc as its negative counterpart.
Sometimes, the different battery types are interchangeable with each other. However, this could lead to improper performance. Be sure to consult your vehicle owner’s manual to ensure you’re getting the battery your key fob needs to operate at the highest level.
