2. Lead-acid battery - Wikipedia

   en.wikipedia.org/wiki/Lead-acid_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.

3. Peukert's law - Wikipedia

   en.wikipedia.org/wiki/Peukert's_law

   For a lead–acid battery is typically between 1.1 and 1.3. For different lead–acid rechargeable battery technologies it generally ranges from 1.05 to 1.15 for VRSLAB AGM batteries, from 1.1 to 1.25 for gel, and from 1.2 to 1.6 for flooded batteries. The Peukert constant varies with the age of the battery, generally increasing (getting worse ...

4. 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 ...

5. Trickle charging - Wikipedia

   en.wikipedia.org/wiki/Trickle_charging

   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 ...

6. Comparison of commercial battery types - Wikipedia

   en.wikipedia.org/wiki/Comparison_of_commercial...

   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.

7. Nickel–cadmium battery - Wikipedia

   en.wikipedia.org/wiki/Nickel–cadmium_battery

   Compared to lead–acid batteries, Ni–Cd batteries have a much higher energy density. A Ni–Cd battery is smaller and lighter than a comparable lead–acid battery, but not a comparable NiMH or Li-ion battery. In cases where size and weight are important considerations (for example, aircraft), Ni–Cd batteries are preferred over the cheaper ...

8. 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 ...

9. Galvanic cell - Wikipedia

   en.wikipedia.org/wiki/Galvanic_cell

   A battery is a set of galvanic cells that are connected together to form a single source of voltage. For instance, a typical 12V lead–acid battery has six galvanic cells connected in series with the anodes composed of lead and cathodes composed of lead dioxide, both immersed in sulfuric acid.
