How does a rechargeable battery work?

You can compare the operation of a rechargeable battery with a battery of a car. When it’ s empty, it can be recharged and used again. With the best possible treatment, these batteries can be recharged up to thousands of times. Because of its constant power (1.2 Volts), a rechargeable battery has virtually the same power from start to finish. Then it stops quite suddenly and has to be loaded. Rechargeable batteries are produced by brands such as Saft and Tadiran.
