  2. Lead-acid battery - Wikipedia

    en.wikipedia.org/wiki/Lead-acid_battery

    AGM cells already have a high acid content in an attempt to lower the water loss rate and increase standby voltage, and this brings about shorter life compared to a lead–antimony flooded battery. If the open circuit voltage of AGM cells is significantly higher than 2.093 volts, or 12.56 V for a 12 V battery, then it has a higher acid content ...

  3. Automotive battery - Wikipedia

    en.wikipedia.org/wiki/Automotive_battery

    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 ...

  4. 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]

  5. State of charge - Wikipedia

    en.wikipedia.org/wiki/State_of_charge

    State of charge. State of charge (SoC) quantifies the remaining capacity available in a battery at a given time and in relation to a given state of ageing. [1] It is usually expressed as percentage (0% = empty; 100% = full). An alternative form of the same measure is the depth of discharge (DoD), calculated as 1 − SoC (100% = empty; 0% = full ...

  6. Deep-cycle battery - Wikipedia

    en.wikipedia.org/wiki/Deep-cycle_battery

    A deep cycle battery powering a traffic signal. A deep-cycle battery is a battery designed to be regularly deeply discharged using most of its capacity. The term is traditionally mainly used for lead–acid batteries in the same form factor as automotive batteries; and contrasted with starter or 'cranking' automotive batteries designed to deliver only a small part of their capacity in a short ...

  7. VRLA battery - Wikipedia

    en.wikipedia.org/wiki/VRLA_battery

    A 12V VRLA battery, typically used in small uninterruptible power supplies and emergency lamps. A valve regulated lead-acid (VRLA) battery, commonly known as a sealed lead-acid (SLA) battery, [1] is a type of lead-acid battery characterized by a limited amount of electrolyte ("starved" electrolyte) absorbed in a plate separator or formed into a gel; proportioning of the negative and positive ...

    en.wikipedia.org/wiki/Peukert's_law

    For example, consider a battery with a capacity of 200 Ah at the C 20 rate (C 20 means the 20-hour rate – i.e. the rate that will fully discharge the battery in 20 hours – which in this case is 10 Amps). If this battery is discharged at 10 A, it will last 20 hours, giving the rated capacity of 200Ah.

  9. Electric vehicle battery - Wikipedia

    en.wikipedia.org/wiki/Electric_vehicle_battery

    An electric vehicle battery is a rechargeable battery used to power the electric motors of a battery electric vehicle (BEV) or hybrid electric vehicle (HEV). They are typically lithium-ion batteries that are designed for high power-to-weight ratio and energy density. Compared to liquid fuels, most current battery technologies have much lower ...
