Battery Services

Certified Local Volkswagen Battery Service in Rensselaer, NY

Your engine is a marvelous machine, producing torque by converting fuel into explosive power. It can fire thousands upon thousands of times every minute, but that’s only possible after it starts up, and the key to starting up is your battery. The easiest way to avoid a dead car is to stay on top of your battery’s condition, and that’s done through battery service. At Cooley Volkswagen, we provide every battery service you could need, so you can know precisely when you need to get your car’s battery replaced.

How a Normally Functioning Battery Works

Car batteries are rechargeable, which allows them to work much longer in your car than they would otherwise. When you turn the key (or push the button), your battery sends vital electricity to the spark plugs. They provide the initial sparks that light your first cylinders full of fuel, and from there, the engine’s motion sustains the movement to get more fuel and vent the by-products. After the engine starts running again, your battery is recharged by the alternator constantly so that it can be ready to do the same the next time you turn on the car.
