A watch battery can be lithium, but not all watch batteries are lithium.
Watch Battery Chemistry
According to the provided reference, watch batteries come in different chemistries. The main types are:
- Silver Oxide
- Alkaline
- Lithium
The reference clearly indicates that Lithium is one type of chemistry used in watch batteries.
Identifying Lithium Watch Batteries
Lithium button cells are typically 3 Volt cells (with a rare exception like the Renata 751, which is a 2V lithium battery). This voltage is a key differentiator from Silver Oxide and Alkaline button cells, which are generally 1.5 Volt.
| Battery Type | Voltage |
|---|---|
| Lithium | Typically 3 Volts |
| Silver Oxide | Typically 1.5 Volts |
| Alkaline | Typically 1.5 Volts |
