Our lives in the digital age depend heavily on the use of batteries. Electronic devices operate on various types of batteries that have a range of lifetimes. There are also rechargeable batteries for laptop computers, digital cameras, camcorders and other devices. In emergencies, your family needs batteries to power smoke detectors, radios and flashlights. Even a car battery plays a vital role in your daily life. Alkaline, lithium ion and nickel-metal hydride are some of the common types of batteries that are available to consumers.
