Cells

In summary, the difference between alkaline and Ag O button cells lies in the type of electrolyte and chemical reactions they use, resulting in varying voltages and capacities. Their lifespan can range from 1-2 years for alkaline cells and 2-3 years for Ag O cells, depending on usage and storage conditions. These two types of cells are not interchangeable due to their different performance capabilities and should be disposed of properly for recycling. While safe to use, it is important to handle them carefully and seek medical attention if ingested.

I read in maplin.co.uk that SR-41 button cells are superior to LR-41s.
In what ways and by how much?

Thanks

SR are silver oxide, they have more energy/volume than LR alkaline and have a flat discharge curve. They also have a long shelf life if not exposed to air.

Thanks. They should be suitable for my laser pointer.

Related to Alkaline and Ag O button cells

1. What is the difference between alkaline and Ag O button cells?

Alkaline button cells use alkaline material such as potassium hydroxide as the electrolyte, while Ag O button cells use silver oxide as the electrolyte. The chemical reactions that occur in these two types of cells are also different, resulting in varying voltages and capacities.

2. How long do alkaline and Ag O button cells typically last?

The lifespan of alkaline and Ag O button cells depends on various factors such as the type of device they are used in, the current draw, and storage conditions. On average, alkaline button cells can last for 1-2 years, while Ag O button cells can last for 2-3 years.

3. Are alkaline and Ag O button cells interchangeable?

In most cases, alkaline and Ag O button cells are not interchangeable. This is because they have different voltages and capacities, which can affect the performance of the device they are used in. It is important to use the type of button cell recommended by the device manufacturer.

4. Can alkaline and Ag O button cells be recycled?

Yes, both alkaline and Ag O button cells can be recycled. They contain materials such as zinc, manganese, and silver that can be extracted and reused. It is important to properly dispose of these batteries to prevent harm to the environment.

5. Are alkaline and Ag O button cells safe to use?

Yes, alkaline and Ag O button cells are safe to use. However, it is important to handle them properly and not expose them to extreme temperatures or puncture them. If swallowed, seek immediate medical attention as these batteries can be harmful if ingested.
