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.
Example charging graph. On the left: per-cell quantities. On the right: example values for a 40 Ah, 6-cell (12 V) battery. Note: schematic illustration; not based on actual measurements. IUoU is a DIN-designation [1] (DIN 41773) for a lead-acid battery charging procedure that is also known as 3-stage charging, 3-phase charging, or 3-step charging.
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.

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 ...
The main disadvantage of lead-acid jump starters is weight, size and battery chemistry. Lead-acid jump starters can be extremely heavy and large, making them less than convenient when transporting between vehicles. Lead-acid batteries may self-discharge if they develop a condition called sulfating, which permanently decreases battery capacity.

Lead reacts with the acid by taking in two electrons, leaving it negative while also producing lead sulfate. The two chemical processes continue as long as an external circuit is available to allow the electrons to flow back into the positive plates, but reaches equilibrium quickly when the battery is disconnected from the circuit.
