Rechargeable (secondary) batteries are an environmentally friendly and cost-effective power source, ideal for high-drain devices and applications requiring frequent battery replacement. Their ability to be recharged and reused multiple times makes them a sustainable choice.

These batteries are available in various chemistries, including nickel-metal hydride (NiMH), lithium-ion (Li-ion), and nickel-cadmium (NiCd). Each type offers distinct advantages, such as long cycle life, high energy density, and robust performance in varying conditions.

Manufacturers like Samsung, LG Chem, and Panasonic lead the market in developing advanced rechargeable battery technologies. Whether for consumer electronics, electric vehicles, or industrial equipment, secondary batteries provide reliable, long-lasting power solutions.
