A rechargeable battery is a type of battery that can be recharged and reused multiple times. It is also known as a secondary battery.
Rechargeable batteries are available in different chemistries, such as lithium-ion, nickel-cadmium, nickel-metal hydride, and lead-acid. They are commonly used in a variety of portable electronic devices such as smartphones, laptops, and cameras.
Rechargeable batteries are environmentally friendly and more cost-effective than disposable batteries in the long run. However, they tend to have a higher upfront cost and may require special charging equipment.
