![]() ![]() A lead-acid battery is an electrical storage device that uses a chemical reaction to store and release energy. The lead-acid battery is still the most widely used 12 V energy storage device. More than one hundred fifty years later, we still have no real cost-effective alternatives for cars, boats, RVs, wheelchairs, scooters, golf carts, and UPS systems. Invented by the French physicist Gaston Planté in 1859, lead-acid was the first rechargeable battery to be used in commercial applications. Lead-acid is the oldest rechargeable battery technology in existence. ![]() Manufacturers, driven by demands from new applications, are constantly pushing the envelope by making changes in the chemistry and structure in search of improved battery life and greater energy density. Today, lithium battery technology continues to evolve at a rapid pace. The unique nature of the various chemistries allows each type to fill special application niches.Įven with wide market adoption in the early 1990s, as societal demands for lightweight portable electronics was burgeoning, the high cost barrier and complexities in battery management circuits would prevent lithium batteries from being used widely in support of larger devices or in scaled energy-storage systems such as large vehicles or uninterruptible power supply (UPS) systems. At first glance, they might all seem to be the same, but there are exploitable, distinct differences between them. There is a diverse family of lithium chemistries available. For example, they are the standard battery technology for high performance in portable electronics ranging from cell phones to laptop computers. Today, lithium batteries are most associated with enhancing “portable” capabilities. Experimental lithium batteries were developed as early as 1912, but it took nearly 70 years before a commercial lithium battery was developed for a wide market.
