    en.wikipedia.org/wiki/List_of_battery_sizes

    All these lithium cells are rated nominally 3 volts (on-load), with open-circuit voltage about 3.6 volts. Manufacturers may have their own part numbers for IEC standard size cells. The capacity listed is for a constant resistance discharge down to 2.0 volts per cell. [143]

    For example, consider a battery with a capacity of 200 Ah at the C 20 rate (C 20 means the 20-hour rate – i.e. the rate that will fully discharge the battery in 20 hours – which in this case is 10 A). If this battery is discharged at 10 A, it will last 20 hours, giving the rated capacity of 200 Ah.

    en.wikipedia.org/wiki/Electric_battery

    Capacity is usually stated in ampere-hours (A·h) (mAh for small batteries). The rated capacity of a battery is usually expressed as the product of 20 hours multiplied by the current that a new battery can consistently supply for 20 hours at 20 °C (68 °F), while remaining above a specified terminal voltage per cell.

    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.

  8. Rechargeable battery - Wikipedia

    en.wikipedia.org/wiki/Rechargeable_battery

    Older rechargeable batteries self-discharge relatively rapidly [vague] and require charging before first use; some newer low self-discharge NiMH batteries hold their charge for many months, and are typically sold factory-charged to about 70% of their rated capacity. Battery storage power stations use rechargeable batteries for load-leveling ...

  9. Electric vehicle battery - Wikipedia

    en.wikipedia.org/wiki/Electric_vehicle_battery

    In practical use, charging speed is more relevant than battery capacity (see rechaging section). Typical EV batteries in passenger cars have a weight of 300 to 1,000 kg (660 to 2,200 lb) [88] resulting in ranges from 150 to 500 km (90 to 310 miles), depending on temperature, driving style and car type.
