car and truck batteries


Every motor vehicle requires a battery. In fact, cars, trucks, buses, and the like, are such integral sources of transportation for most, that it makes sense people often think of these types of batteries first when recycling is concerned. Because their primary function is to start the engine, vehicle batteries are sometimes referred to as cranking batteries, and their power is measured in CA (cranking amps). The most common types of lead-acid vehicle batteries include flooded or AGM.

MORE INFORMATION

Most, if not all vehicles that require a quick, powerful current to start it's engine, use flooded or wet cell batteries. Flooded batteries, still by far the most popular car/truck battery, work by means of a chemical interaction between the lead plates and the sulfuric acid electrolyte solution. A high number of thin plates and an ample amount of sulfuric acid within the battery provides a large surface area for energy exchange. The resulting high initial current makes them ideal for their application in starting engines. The starting power of a flooded battery is measured in CA (cranking amps). Batteries with a higher CCA rating are used for starting larger engines. This includes truck and heavy construction equipment which are often 3-4 times larger and heavier than a car battery.

In recent times AGM batteries have grown into popularity for their ability to withstand greater temperature extremes and vibrations. They also charge up to 5x faster than flooded batteries, do not spill, and have a slower discharge rate when not in use. AGM batteries contains plates that are separated by polyester or fiberglass mats, which absorb and hold around 95% of the acid within the battery, preventing spilling and fluid loss. All of the chemical reactions that occur within the battery are self contained, and gasses and liquids that result from the chemical reactions between the sulfuric acid and lead plates recombine internally. The batteries also contain a relief venting valve to allow the release from the minor gassing that results from charging, while also preventing air from entering the battery by only opening under low pressure.

The reason some people choose AGM batteries in their vehicles, despite their higher initial investment and sensitivity to overcharging, is their durability and longevity. These types of batteries, originally developed for use in military aircraft and equipment, are typically found in start/stop vehicles, as well as those equipped with a lot of electronics.

   KEY POINTS

  • Are one of the most common lead-acid battery
  • Designed to crank the engine and provide power to on-board lights and electronics
  • Utilize 12V Wet Cell Lead-Acid and AGM Lead-Acid, with the most common being flooded
  • AGM batteries work better in colder temperatures, withstand vibrations, charge faster, and have a slower rate of discharge
  • Flooded batteries require maintenance, but are the most cost effective option
  • Alternator charges battery when not in use
  • Must be replaced every 2-5 years
  • Can be scrapped for money when batteries go bad
