The word “battery” comes from the Old French word baterie, meaning “action of beating,” relating to a group of cannons in battle. In the endeavor to find an energy storage device, scientists in the 1700s adopted the term “battery” to represent multiple electrochemical cells connected together.
A battery is a device that converts chemical energy contained within its active materials directly into electric energy. Car batteries fall into the designation of SLI batteries, which stands for Starting, Lighting and Ignition. SLI batteries are rechargeable lead-acid batteries designed for applications that require lots of power upfront to start a vehicle’s engine, followed by slower, more consistent delivery to keep the vehicle and its accessories running.
A typical 12 volt lead acid auto battery contains 6 separate battery cells. Each cell contains a series of rectangular grids, housing a number of lead plates that is divided by a series of separators.

The separators are made of a thin, porous material that allows ionic current to flow between the positive and negative plates, while preventing them from short circuiting.

How Does Your Car Start?

When you insert the key in your car’s ignition and turn the switch or push the button to ‘ON,’ a signal is sent to the car’s battery. Upon receiving this signal, the car battery converts chemical energy into electrical energy. This electrical power is delivered to the starter to crank the engine. The battery also provides power to the car’s lights and other accessories.

How Do You Recharge a Car Battery?

Once a battery is discharged, it needs to be recharged in order to function again. Your alternator is responsible for recharging the battery using a belt-driven system that turns the rotor in the alternator cables.


Super Crank Battery are designed to provide enormous cranking with ultra deep cycle reserve power. Super Crank unique plate design made of 99% pure lead – not lead alloy, like many conventional batteries ensures its extraordinary performance. Super Crank batteries crushed expectations when drivers needed them most – in extreme weather conditions and for high-performance output. Today, Super Crank batteries meet the power-hungry demands of new vehicles. Punch grid technology provides nearly three times more corrosion resistance, increased durability and full grid utilization for 60% more electrical flow compared to other grid designs.
