  2. AA battery - Wikipedia

    en.wikipedia.org/wiki/AA_battery

    A Li-ion 1.5V AA-size battery, sold by the Chinese company Kentli as "Kentli PH5" since 2014 and with similar batteries later available from other suppliers is a AA-sized battery housing containing a rechargeable 3.7 V Li-ion cell with an internal buck converter at the positive terminal to reduce the output voltage to 1.5 V. [19] The Kentli ...

  3. Alkaline battery - Wikipedia

    en.wikipedia.org/wiki/Alkaline_battery

    An AA-sized alkaline battery might have an effective capacity of 3000 mAh at low drain, but at a load of 1 ampere, which is common for digital cameras, the capacity could be as little as 700 mAh. [12] The voltage of the battery declines steadily during use, so the total usable capacity depends on the cutoff voltage of the application.

  4. 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.

    The ESR and the voltage of a notional ideal voltage source within the battery are theoretical constructs that represent an approximation to physical properties of the battery chemistry. The graph data is adapted from the data-sheet for a Duracell Ultra-Power AA MX1500 Alkaline-Manganese battery.

    en.wikipedia.org/wiki/Lithium_metal_battery

    CR2032 lithium button cell battery Lithium 9 volt, AA, and AAA sizes. The top object is a battery of three lithium-manganese dioxide cells; the bottom two are lithium-iron disulfide cells and are compatible with 1.5-volt alkaline cells. Lithium metal batteries are primary batteries that have metallic lithium as an anode.
