Lead acid cells were invented in 1859 by the French Physicist Gaston Plante‚ and are the oldest types of rechargeable batteries. These types of batteries typically weigh at 5kg‚ but can range from half a kilogram to over 30 kilograms on the consumer market. Though their chemistry means a very low energy-to-weight and energy-to-volume ratio in comparison to other modern batteries‚ their ability to supply high surge currents means that the cells maintain a large power-to-weight ratio. This makes them

The dry cell or Leclanche cell was the first commercial battery and therefore had a big impact on society. It is the most common and the cheapest of the commercially available cell and is most widely used in torches‚ portable radios and battery-operated clocks. It is best used for low drain appliances‚ which need only small currents such as portable items (radio). It consists of a zinc outer casting‚ the anode‚ an aqueous paste of ammonium chloride and a mixture of powdered carbon and manganese

SIMULATION FOREGROUND READING Back Bay Battery‚ Inc. Overview The battery industry is enormous‚ with worldwide revenues of approximately $45 billion. It is highly fragmented with at least 20 major 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
