  2. Lithium iron phosphate battery - Wikipedia

    en.wikipedia.org/wiki/Lithium_iron_phosphate_battery

    The energy density (energy/volume) of a new LFP battery as of 2008 was some 14% lower than that of a new LiCoO 2 battery. [46] Since discharge rate is a percentage of battery capacity, a higher rate can be achieved by using a larger battery (more ampere hours) if low-current batteries must be used.

  3. Lithium iron phosphate - Wikipedia

    en.wikipedia.org/wiki/Lithium_iron_phosphate

    The most notable difference between lithium iron phosphate and lead acid is the fact that the lithium battery capacity shows only a small dependence on the discharge rate. With very high discharge rates, for instance 0.8C, the capacity of the lead acid battery is only 60% of the rated capacity.

  4. Comparison of commercial battery types - Wikipedia

    Under certain conditions, some battery chemistries are at risk of thermal runaway, leading to cell rupture or combustion.As thermal runaway is determined not only by cell chemistry but also cell size, cell design and charge, only the worst-case values are reflected here.

    The remaining capacity can also be withdrawn by reducing the current. For example, when the battery in the previous example reaches the cut-off voltage at 200 A, tapering the current down as necessary to keep the voltage at the low voltage cut-off value will enable nearly all the missing capacity to be taken from the battery (albeit over a ...

  6. Electric battery - Wikipedia

    It is defined as the current through the battery divided by the theoretical current draw under which the battery would deliver its nominal rated capacity in one hour. [51] It has the units h −1. Because of internal resistance loss and the chemical processes inside the cells, a battery rarely delivers nameplate rated capacity in only one hour.

    A Battery: Eveready 742: 1.5 V: Metal tabs H: 101.6 L: 63.5 W: 63.5 Used to provide power to the filament of a vacuum tube. B Battery: Eveready 762-S: 45 V: Threa­ded posts H: 146 L: 104.8 W: 63.5 Used to supply plate voltage in vintage vacuum tube equipment. Origin of the term B+ for plate voltage power supplies.

  8. Automotive battery - Wikipedia

    en.wikipedia.org/wiki/Automotive_battery

    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.

  9. 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 protocol—how much voltage and current, for how long and what to do when charging is complete—depends on the size and type of the battery being charged.
