  2. Ampere-hour - Wikipedia

    en.wikipedia.org/wiki/Ampere-hour

    An AA size dry cell has a capacity of about 2,000 to 3,000 milliampere-hours. An average smartphone battery usually has between 2,500 and 4,000 milliampere-hours of electric capacity. Automotive car batteries vary in capacity but a large automobile propelled by an internal combustion engine would have about a 50-ampere-hour battery capacity.

    For reference, about 10,000 100-watt lightbulbs or 5,000 computer systems would be needed to draw 1 MW. Also, 1 MW is approximately 1360 horsepower . Modern high-power diesel-electric locomotives typically have a peak power of 3–5 MW, while a typical modern nuclear power plant produces on the order of 500–2000 MW peak output.

  4. AA battery - Wikipedia

    Its capacity at 250 mA drain is 1,700 mAh at 1.5 V, less than other chemistries, limited by the low efficiency of the step-down converter. [21] Some later Li-ion AA batteries advertise their capacity in milliwatt-hours (mWh) instead of the usual milliampere-hours (mAh), so a customer's attention is drawn to the figure, typically a claimed 3,000 ...

  5. Battery charger - Wikipedia

    en.wikipedia.org/wiki/Battery_charger

    A 10-ampere-hour battery could take 15 hours to reach a fully charged state from a fully discharged condition with a 1-ampere charger as it would require roughly 1.5 times the battery's capacity. Public EV charging stations often provide 6 kW (host power of 208 to 240 V AC off a 40-ampere circuit). 6 kW will recharge an EV roughly six times ...

  7. Kilowatt-hour - Wikipedia

    en.wikipedia.org/wiki/Kilowatt-hour

    This results in a 500 mA USB device running for about 3.7 hours on a 2,500 mAh battery, not five hours. The Board of Trade unit (B.T.U.) [17] is an obsolete UK synonym for kilowatt-hour. The term derives from the name of the Board of Trade which regulated the electricity industry until 1942 when the Ministry of Power took over. [18]
