A Class I recall situation is one in which there is a reasonable probability that the use of, or exposure to, a volatile product will cause serious adverse health consequences or death (21 CFR 7.3(m)(1)).
Electrical energy can be converted back into kinetic energy in electric motors: this happens with the windscreen wipers and the starter motor. Electrical energy is converted into light energy in the headlights. In fact the only kind of energy which you will not find in your car is nuclear energy.
Your car's battery is tasked with storing electrical energy, power that is needed to ignite the starter and keep your car running. A weak or dead battery will leave you stranded, while a healthy car battery will perform the functions it is designed to perform. With electrical energy stored, your car's battery will have sufficient juice to supply power to the starter, which, when turned, helps to start your car's engine. A problem with your battery, connecting points, wires or starter will keep your engine from running. The moment your engine starts to run, the alternator is activated to supply electricity generated by the movement of two pulleys and a drive belt. As long as the alternator is working fine, important functions such as the headlights, the wipers, the sound system and climate control will work.
