  2. Float voltage - Wikipedia

    en.wikipedia.org/wiki/Float_voltage

    Float voltage is the voltage at which a battery is maintained after being fully charged to maintain that capacity by compensating for self-discharge of the battery. [1] The voltage could be held constant for the entire duration of the cell's operation (such as in an automotive battery) or could be held for a particular phase of charging by the charger. [2]

  3. Nickelā€“metal hydride battery - Wikipedia

    en.wikipedia.org/wiki/Nickelā€“metal_hydride_battery

    At this charge rate, Panasonic recommends to terminate charging when the voltage drops 5ā€“10 mV per cell from the peak voltage. [23] Since this method measures the voltage across the battery, a constant-current (rather than a constant-voltage) charging circuit is used.

  4. Battery charger - Wikipedia

    en.wikipedia.org/wiki/Battery_charger

    A battery charger, recharger, or simply charger, [ 1][ 2] is a device that stores energy in an electric battery by running current through it. The charging protocolā€”how much voltage, current, for how long and what to do when charging is completeā€”depends on the size and type of the battery being charged. Some battery types have high ...

  5. Lead-acid battery - Wikipedia

    en.wikipedia.org/wiki/Lead-acid_battery

    IUoU battery charging is a three-stage charging procedure for lead-acid batteries. A lead-acid battery's nominal voltage is 2.2 V for each cell. For a single cell, the voltage can range from 1.8 V loaded at full discharge, to 2.10 V in an open circuit at full charge.

  6. Lithium-ion battery - Wikipedia

    en.wikipedia.org/wiki/Lithium-ion_battery

    Nominal cell voltage. 3.6 / 3.7 / 3.8 / 3.85 V, LiFePO4 3.2 V, Li4Ti5O12 2.3 V. A lithium-ion or Li-ion battery is a type of rechargeable battery that uses the reversible intercalation of Li + ions into electronically conducting solids to store energy. In comparison with other commercial rechargeable batteries, Li-ion batteries are ...

  7. Rechargeable battery - Wikipedia

    en.wikipedia.org/wiki/Rechargeable_battery

    Rechargeable battery. A battery bank used for an uninterruptible power supply in a data center. A rechargeable lithium polymer mobile phone battery. A common consumer battery charger for rechargeable AA and AAA batteries. A rechargeable battery, storage battery, or secondary cell (formally a type of energy accumulator ), is a type of electrical ...

  8. Lithium iron phosphate battery - Wikipedia

    en.wikipedia.org/wiki/Lithium_iron_phosphate_battery

    The lithium iron phosphate battery ( LiFePO. 4 battery) or LFP battery ( lithium ferrophosphate) is a type of lithium-ion battery using lithium iron phosphate ( LiFePO. 4) as the cathode material, and a graphitic carbon electrode with a metallic backing as the anode. Because of their low cost, high safety, low toxicity, long cycle life and ...

  9. 18650 battery - Wikipedia

    en.wikipedia.org/wiki/18650_battery

    Each cell has a capacity of 2450 mAh. An 18650 battery [1] or 1865 cell [2] is a cylindrical lithium-ion battery common in electronic devices. The batteries measure 18 mm (0.71 in) in diameter by 65 mm (2.56 in) in length, giving them the name 18650. [3] The battery comes in many nominal voltages depending on the specific chemistry used.
