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.
About 60% of the weight of an automotive-type lead–acid battery rated around 60 A·h is lead or internal parts made of lead; the balance is electrolyte, separators, and the case. [8] For example, there are approximately 8.7 kilograms (19 lb) of lead in a typical 14.5-kilogram (32 lb) battery.
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. [64]
The same physically interchangeable cell size or battery size may have widely different characteristics; physical interchangeability is not the sole factor in substituting a battery. [ 1 ] The full battery designation identifies not only the size, shape and terminal layout of the battery but also the chemistry (and therefore the voltage per ...
Vosburg v. Putney, 80 Wis. 523, 50 N.W. 403 (Wisc. 1891), was an American torts case that helped establish the scope of liability in a battery. The case involved an incident that occurred on February 20, 1889 in Waukesha, Wisconsin. A 14-year-old boy, Andrew Vosburg, was kicked in his upper shin by an 11-year-old boy, George Putney, while the ...
Experts say vehicle-based attacks are simple for a 'lone wolf' terrorist to plan and execute, and challenging for authorities to prevent.

Battery electric vehicles have lower maintenance costs compared to internal combustion vehicles since electronic systems break down much less often than the mechanical systems in conventional vehicles, and the fewer mechanical systems onboard last longer due to the better use of the electric engine. Electric cars do not require oil changes and ...
