   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.

3. Peukert's law - Wikipedia

   en.wikipedia.org/wiki/Peukert's_law

   Peukert's law brings a certain degree of fire-safety to many battery designs. It limits the maximum output power of the battery. For example, starting a car is safe even if the lead–acid battery dies. The primary fire hazard with lead–acid batteries occurs during over-charging when hydrogen gas is produced.

4. Power-to-weight ratio - Wikipedia

   en.wikipedia.org/wiki/Power-to-weight_ratio

   Battery discharge profiles are often described in terms of a factor of battery capacity. For example, a battery with a nominal capacity quoted in ampere-hours (Ah) at a C/10 rated discharge current (derived in amperes) may safely provide a higher discharge current – and therefore higher power-to-weight ratio – but only with a lower energy ...

6. Lead–acid battery - Wikipedia

   en.wikipedia.org/wiki/Lead–acid_battery

   Consider a battery that has been completely discharged (such as occurs when leaving the car lights on overnight, a current draw of about 6 amps). If it then is given a fast charge for only a few minutes, the battery plates charge only near the interface between the plates and the electrolyte.
