A typical 12 V, 40 Ah lead-acid car battery. An automotive battery, or car battery, is a rechargeable battery that is used to start a motor vehicle.. Its main purpose is to provide an electric current to the electric-powered starting motor, which in turn starts the chemically-powered internal combustion engine that actually propels the vehicle.
Cahill had tremendous ambitions for his invention; he wanted telharmonium music to be broadcast into hotels, restaurants, theaters, and even houses via the telephone line. [3] At a starting weight of 7 tons (and up to 200 tons) and a price tag of $200,000 (approx. $5,514,000 today), only three telharmoniums were ever built, and Cahill's vision ...

The firm pioneered the dynamo-charged battery principle and in 1911 it produced the world's first lighting system used on a double-decker bus. [12] By 1918 1,000 employees were making vehicle electrics and aircraft magnetos. [12] Wireless components were also made from 1923. [12] In 1926 CAV was bought by Lucas. [12]
