2. Ampere-hour - Wikipedia

   en.wikipedia.org/wiki/Ampere-hour

   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. Since one ampere-hour can produce 0.336 grams of aluminium from molten aluminium ...

3. Automotive battery - Wikipedia

   Ampere hours (Ah or A·h) is a unit related to the energy storage capacity of the battery. This rating is required by law in Europe. This rating is required by law in Europe. The ampere hour rating is generally defined as the product of (the current a battery can provide for 20 hours at a constant rate, at 80 degrees F (26.6 °C), while the ...

4. Peukert's law - Wikipedia

   en.wikipedia.org/wiki/Peukert's_law

   is the actual time to discharge the battery (in hours). Using the above example, if a battery rated for 100 ampere-hours at a 20-hour rate has a Peukert constant of 1.2 and is discharged at a rate of 10 amperes, it would be fully discharged in time (), which is approximately 8.7 hours. It would therefore deliver only 87 ampere-hours rather than ...

5. Lead–acid battery - Wikipedia

   en.wikipedia.org/wiki/Lead–acid_battery

   The sum of the molecular masses of the reactants is 642.6 g/mole, so theoretically a cell can produce two faradays of charge (192,971 coulombs) from 642.6 g of reactants, or 83.4 ampere-hours per kilogram for a 2-volt cell (or 13.9 ampere-hours per kilogram for a 12-volt battery). This comes to 167 watt-hours per kilogram of reactants, but in ...

6. Electric battery - Wikipedia

   en.wikipedia.org/wiki/Electric_battery

   An electric battery is a source of electric power consisting of one or more electrochemical cells with external connections [1] for powering electrical devices. When a battery is supplying power, its positive terminal is the cathode and its negative terminal is the anode. [2] The terminal marked negative is the source of electrons.

   Nissan Leaf cutaway showing part of the battery in 2009. An electric vehicle battery is a rechargeable battery used to power the electric motors of a battery electric vehicle (BEV) or hybrid electric vehicle (HEV). They are typically lithium-ion batteries that are designed for high power-to-weight ratio and energy density.

9. Power-to-weight ratio - Wikipedia

   en.wikipedia.org/wiki/Power-to-weight_ratio

   Battery discharge profiles are often described in terms of a factor of battery capacity. For example, a battery with a nominal capacity quoted in ampere-hours (Ah) at a C/10 rated discharge current (derived in amperes) may safely provide a higher discharge current – and therefore higher power-to-weight ratio – but only with a lower energy ...
