    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.

    en.wikipedia.org/wiki/Leadacid_battery

    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.

    en.wikipedia.org/wiki/Rechargeable_battery

    The leadacid battery, invented in 1859 by French physicist Gaston Planté, is the oldest type of rechargeable battery. Despite having a very low energy-to-weight ratio and a low energy-to-volume ratio, its ability to supply high surge currents means that the cells have a relatively large power-to-weight ratio .

    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.

    The Headway 38120HP cells are used in high-discharge environments as they have very good continuous/peak discharge rates (10C/25C). Because four cells in series produces a voltage range similar to 6 cells of lead-acids and their fire-resistant properties, they can be used to replace a 12 V lead-acid car battery.

    A 12V VRLA battery, typically used in small uninterruptible power supplies and emergency lamps.. A valve regulated leadacid (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 ...
