6-QW-45 Automotive/Car Lead Acid Battery

Lead Acid batteries which were the first rechargeable battery ever built and are still the most common rechargeable battery on the market to this day. Due to the low cost and high power-to-weight ratio lead-acid batteries remain in high demand as starter batteries. However, because they also have low energy-to-weight and energy-to-volume ratios they are often chosen for stationary applications rather than mobile and portable applications like electric vehicles or hand tools. Lead-acid battery technologies should continue to be used extensively for off-grid solar applications for years to come.

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. Once the engine is running, power for the car's electrical systems is still supplied by the battery, with the alternator charging the battery as demands increase or decrease.
