    0.1: 12.5 × 1.6 Used in some lighted watches and some LED decorator lights (electronic tea candles). CR1220: 5012LC: 35–40: 0.1 (CR) 0.03 (BR) 12.5 × 2.0 Used in keychain LED flashlights, and in some digital cameras to keep the time and date function running even when the main battery is taken out of the camera.

  3. IUoU battery charging - Wikipedia

    en.wikipedia.org/wiki/IUoU_battery_charging

    As a result of this current, the battery absorbs a charge and its voltage rises. The charger limits the maximum voltage to U max, a constant or temperature-dependent maximum, typically around 2.4 V per cell. Once the U max voltage is reached, typically when the battery is charged to 70–80% of its capacity, [1] the charger enters the Uo-phase ...

    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.

    Pump Express Plus supports elevated voltage levels of 7, 9 and 12 volts, whereas the specification for Quick Charge 2.0 lacks the 7-volt level. A 20-volt level was added in a revision named "class B" of the specification. [12] [13] The voltage range of the successor Pump Express Plus 2.0 is between 5 volts and 20 volts, with 0.5 volts steps.

  7. Trickle charging - Wikipedia

    en.wikipedia.org/wiki/Trickle_charging

    [1] [2] 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 ...

  8. Rechargeable battery - Wikipedia

    en.wikipedia.org/wiki/Rechargeable_battery

    The energy used to charge rechargeable batteries usually comes from a battery charger using AC mains electricity, although some are equipped to use a vehicle's 12-volt DC power outlet. The voltage of the source must be higher than that of the battery to force current to flow into it, but not too much higher or the battery may be damaged.

  9. 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).
