Batteries turn chemical energy into the energy all the electrical components in your car need to work, including the ignition. The wrong, damaged or old battery can leave your car's electronics non-functional and even cause other parts on your car to become damaged or non-operational. Your battery and alternator feed off of each other and if one isn't working, neither will the other. The alternator is responsible for distributing the power the battery gives it to all the different electronic components and for charging the battery so that it keeps working. Here you will find everything you need to keep your electronics working properly, including alternators, batteries, battery chargers, battery testers and more!
