Rechargeable batteries are a type of electrical battery that can be charged and discharged multiple times. They are used in a wide variety of applications, including portable electronics, power tools, and electric vehicles. There are many different types of rechargeable batteries, each with its own unique characteristics and advantages.
The most common type of rechargeable battery is the lead-acid battery. Lead-acid batteries are relatively inexpensive and have a long lifespan, but they are also heavy and bulky. Nickel-cadmium (NiCd) batteries are another common type of rechargeable battery. NiCd batteries are more lightweight than lead-acid batteries and have a higher energy density, but they also have a shorter lifespan. Nickel-metal hydride (NiMH) batteries are a newer type of rechargeable battery that offers a good balance of performance and price. NiMH batteries are lightweight, have a high energy density, and have a long lifespan.
