The lead-acid battery is a type of rechargeable battery first invented in 1859 by French physicist Gaston Planté. It is the first type of rechargeable battery ever created. Compared to modern rechargeable batteries, lead-acid batteries have relatively low energy density. Despite this, they are able to supply high surge currents.
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 current to a trickle, hence the name. In such cases, the trickle charging equals the ...
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 ...
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]
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 ...
Galvanic cell. Galvanic cell with no cation flow. A galvanic cell or voltaic cell, named after the scientists Luigi Galvani and Alessandro Volta, respectively, is an electrochemical cell in which an electric current is generated from spontaneous oxidation–reduction reactions. A common apparatus generally consists of two different metals, each ...
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 ...
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 ...
