THE IMPORTANCE OF A Battery Replacement

What is a car battery and how does it work?

A car battery provides electrical power to start your vehicle. It also powers all of the electronics on board until the engine is running. When you activate the ignition, the starter pulls power from the battery to start the engine. In the process, the starter depletes the battery slightly. Once the engine is running, however, the alternator (a generator attached to the engine) recharges the battery and takes over all of the other electrical functions. The battery also acts as a buffer to the electrical system in the case of a power surge or excessive current draw. Note, this is not the same component as the high-voltage battery found in an electric or hybrid vehicle.

COMMON SYMPTOMS

When should a car battery be replaced?

A fully-charged car battery should measure 12.6 volts at rest. If the battery consistently falls below that measure, it likely needs to be replaced. Actually, a battery that tests below 12 volts is considered a “dead” battery. When that is the case, you may notice the following signs:

FREQUENCY OF INSPECTION

How does a technician perform A Battery Replacement ?

To replace a car battery, a mechanic will first install a temporary power source to preserve the computer memory of your navigation, audio, engine management, and other electronic systems. With the electronics safeguarded, the technician will disconnect the negative terminal from the battery, followed by the positive cable. The battery tie down device is loosened, and the old battery is removed and discarded according to state and local regulations. The cable ends and wires are carefully inspected for signs of corrosion or other damage before the new battery is installed, strapped down, connected, and dressed with an anti-corrosion compound.
At this point, some vehicles may require programming of the Powertrain Control Module (PCM). Finally, your vehicle is started and the output of the charging system is tested.

Other Questions Customers Ask

How much should a car battery cost?
Depending on the make and model of your vehicle, which will determine the type and power requirements of a car battery, you can expect to pay anywhere from $150 - $200 for a quality battery and as much as $250 or more for a premium model.
How often should you change a car battery?
Most drivers will find that their vehicle’s battery will last four or five years or more. Drivers in extremely hot climates are not so fortunate, as their batteries suffer with the heat and do not last as long. REplace your battery when you find that it no longer holds a full charge.
How long can a car battery last without driving?
If you have a vehicle that is driven less frequently, or one that will be stored for a prolonged period of time, make sure to install a smart charger or tender to keep the battery fully charged. Otherwise, a battery left in the vehicle unattended may lose its charge in a matter of weeks.
