Large batteries
Large batteries are usually of the rechargeable lead-acid type. Applications include starting batteries for automobiles and deep cycle batteries for leisure use.[3] Starting batteries are usually 12 volt batteries containing six lead-acid cells. Large vehicles, such as trucks and buses may have two 12 volt batteries connected in series to give 24 volts.
Even larger batteries are used for powering Submarines[4] and Electric Vehicles, such as forklift trucks.[5]
