A 3v 2025 battery is a small, button-shaped battery that is commonly used in a variety of electronic devices such as watches, calculators, and key fobs. It is a primary battery, which means that it cannot be recharged once it has been discharged.
3v 2025 batteries are made up of three main components: a positive terminal, a negative terminal, and an electrolyte. The positive terminal is made of metal, the negative terminal is made of carbon, and the electrolyte is a liquid or paste that contains ions. When the battery is connected to a circuit, the ions in the electrolyte move from the negative terminal to the positive terminal, creating an electrical current.
