    It produced a lot more hydrogen gas when being charged, meaning it could not be sealed, and the charging process was less efficient (it was, however, cheaper). Seeing a way to make a profit in the already competitive lead-acid battery market, Thomas Edison worked in the 1890s on developing an alkaline based battery that he could get a patent on ...

  3. Nine-volt battery - Wikipedia

    en.wikipedia.org/wiki/Nine-volt_battery

    The nine-volt battery, or 9-volt battery, is an electric battery that supplies a nominal voltage of 9 volts. Actual voltage measures 7.2 to 9.6 volts, depending on battery chemistry. Batteries of various sizes and capacities are manufactured; a very common size is known as PP3, introduced for early transistor radios.

    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 that will ...

  7. Trickle charging - Wikipedia

    en.wikipedia.org/wiki/Trickle_charging

    A battery under continuous float voltage charging is said to be float-charging. [3] For lead–acid batteries under no-load float charging (such as in SLI batteries ), trickle charging happens naturally at the end-of-charge, when the lead–acid battery internal resistance to the charging current increases enough to reduce additional charging ...

    Constant voltage. Constant voltage charging is a widely used charging method involving constant voltage between the battery poles. The starter battery uses constant voltage charging when the vehicle is running. If the specified voltage constant value is appropriate, it can ensure that the battery is fully charged, while also minimizing gas and ...

    en.wikipedia.org/wiki/Qi_(standard)

    The standard allows compatible devices, such as smartphones, to charge their batteries when placed on a Qi charging pad, which can be effective over distances up to 4 cm (1.6 in). [2] The Qi standard is developed by the Wireless Power Consortium. [1] As a universal, open standard Qi-enabled devices are able to connect to Qi chargers from any ...
