What is Automotive battery

Automotive batteryAn automotive battery is a battery that can provide energy for electric driving. Traditionally, this began, lighting, for insurance, called flash, its main objective is to start the engine.

When the engine is running, alternator provides the power for the car. Normally, the battery capacity is less than the resolution of the rupee by three percent. SLI batteries, AC current measure is designed to release a high burst, then quickly looked to be waning. They are not designed for deep discharge and complete discharge of the battery can be reduced lifespan.

The engine started and SLI batteries for extra power provided by the vehicle electrical system supply exceeds the needs of those. It is also a stabilizer, the evening can be harmful voltage spikes.  While the engine is running, the alternator voltage regulator includes provides much power between 13.5 and 14.5 and to keep output.

Automotive battery History

Home Cars, the battery will not be limited to their email systems. The bell was used instead of an electric horn, gas powered vehicles and crank the engine was started with. Car battery electric sṭāṭar was appointed in 1920 consisted of approximately widely used in cars. The need for an outlet sealed batteries, created in 1971.

Start with the first 6-volt and positive- and those methods can be designed to have a direct positive battery terminal connected to the chassis ground, system. Today, all vehicles have a negative ground system. The negative battery terminal is connected to the cars.

When they start using the Hudson Motor Car Company in 1918 passed the first automotive battery using battery batteries Council. BCI ‘organization has set standards for battery dimensions.

Cars that use 6 V electrical system, and hence the mid-1950s to 6 V battery had. 6 to 12 with the high compression ratio of the engine changes from a V need more power to start. 6 V longer stay with the initial low power, for example, requires the small car, Volkswagen Beetle and Citroen 2CV 1970 in mid-1960.

In 1990, the standard 42V electrical system was proposed. It is the most powerful, electrically reasons Accessories, cable harnesses and light motor vehicles was intended to. High-efficiency motors abundantly available, a new wireless technology and digital control systems and high-voltage start/generators used in hybrid vehicles have been instrumental in the drive to focus attention on the main car voltage switch systems.

Automotive battery design

  • Low maintenance or maintenance-free: in the past, in the form of battery electric station maintenance required. Retain their power to battery fluid for modern battery life. When the batteries weaken, they left in search of the car battery completely drained, for example, a deep discharge that is not. Battery life can be reduced when the Jackets the lead sulfate deposited plate electrodes, and a third or more.


  • VRLA: The absorption glass cover (AGM) tolerate more deep discharge, known as batteries, but are more expensive.
    A series of circuits in the battery usually six galvanic cells. Each cell provides 2.1 volts to 12.6 volts for all of the full charges. Front storage battery cells in each plate of lead options (a cathode) and lead dioxide (lead anode immersed in a greased) solution of sulfuric acid electric. True standard cells have the potential to lower the standard. This causes a chemical reaction on allowing the electrons to flow through them, to produce electricity conductors. The battery out, when the electronic acid changes their surface, react with the lead sulfate plate material. When the battery looked distraught, chemical reactions reversed: the lead sulfate reforms into lead dioxide. With sheets restored back to their original, this process can be used again and again. Use of several vehicles starting batteries. Porsche 911 GT3 RS has an option to save weight 2010 lithium-ion battery. There may be a series of two heavy duty 24 V battery system to provide or may have been 24 teams in parallel-series batteries


  • Physical Form: physical size battery, the terminal posts and the type, style, Ampere-hour battery energy storage
  • Ampere-hour battery energy storage capacity and are connected unit. This rating is required by law in Europe.
  • DC (CA) Cranking: current battery amount 32 ° F (0 ° C) can be given. Cold cranking current (CCA) battery current amount (-18 ° C) can be provided at F at 0 °. Computer controlled fuel injection engines of modern cars and numbers start to take more than a few seconds to CCA, they are less important than the days kābiyuerṭar.
  • Hot cranking current (HCA) batteries 80 ° F (26.7 ° C) is the amount of current that can be provided. For free for 30 seconds and at least one cell of 1.2 volts (7.2 volts for 12-volt battery) temperature can be defined to maintain the current rating as the front-acid batteries.
  • Reserve capacity minutes (RCM) and the ability to sustain the battery at least the electrical loads; The volt voltage drops below 10.5 F ° 80 before (27 ° C) in the front-acid batteries continue to offer the current 25, it (minutes) is defined as the period.
  • Group size batteries Council (BCI approval) a length, width, height, and physical dimensions as batteries, displays. The group has decided to organize.
  • The automotive battery has a code to help consumers in the United States recently. When batteries are stored, they can start losing their charge. In the month before the batteries of 10-5 numerical code or a K-5 grade is October 2015.
