Back Bay Battery, Inc.


The battery industry is enormous, with worldwide revenues of approximately $45 billion. It is highly fragmented with at least 20 manufacturers in each technology segment. Because of the wide range of applications of batteries, companies have tended to specialize in a particular technology or market application. Disposable batteries, such as the widely available carbon-zinc and alkaline cells, are available in standard sizes such as AA, C, and D, and they are a fast-moving consumer-good category with emphasis on manufacturing efficiency and scale, marketing and branding, and distribution efficiency.

One of the earliest forms of rechargeable battery was the wet lead-acid battery, the chemistry for which was invented in 1859. The application that drove this battery into prominence was to power a starter motor for vehicles, but today lead-acid batteries are commonly used for uninterruptible power supplies-in forklift trucks, golf carts, boats and submarines, and vehicles for indoor operation. They are inexpensive, albeit heavy. A variant on the lead-acid battery is the Gel Cell, which is a sealed lead-acid battery with a gelified electrolyte, allowing a higher degree of portability.

Smaller rechargeable batteries began as size-compatible replacements for disposable batteries and used technologies such as nickel-cadmium (NiCd), nickel-iron (Ni-Fe), nickel metal hydride (NiMH), lithium ion (Li-ion) and lithium polymer. As demands for portable electronic devices such as laptop computers, music players, and cellular telephone handsets rose, makers responded...
