Electrical System

id you know that summer heat greatly reduces battery life? You may not notice until winter when your battery is called upon to deliver more power to start the engine. Come visit Automotive Techniques for a 7-point battery inspection before your battery leaves you out in the cold.

Warning Signs:

  • The battery light comes on.
  • The alternator is making a noise.
  • The starter motor turns the engine slowly or unevenly.
  • You hear a clicking or chattering noise when you turn on the ignition.


The battery in your car supplies electricity to your vehicle, powering the starter, ignition, lights, stereo, and other components. As you drive, the car’s alternator uses the engine’s power to recharge the battery. Since the average battery lasts approximately four years, you will need to replace your battery at some point.

Our technicians will check the power specifications, particularly the Cold Cranking Amps rating (CCA) and Reserve Capacity (RC), and make sure your battery has the correct ratings for your vehicle. The CCA refers to the battery’s capacity for starting your engine in colder temperatures – essential for the Canadian winter. The RC rating refers to the battery’s Reserve Capacity – the time in minutes that the battery will power essential car functions if the alternator or charging system fails.

Your vehicle’s electrical system is always on as the battery continues to run the computers that operate the vehicle so they retain their settings. These use little power and under normal circumstances will not drain the battery.


Like all batteries your car battery would eventually go dead without a built-in recharging system. The recharging system consists of the alternator, alternator drive belt, the battery, the voltage regulator, main fuses, charge indicator, cables and wiring harness.

A battery stores about enough power to get your vehicle started. After that, it’s up to the alternator to re-charge the battery and create enough electricity to power your vehicle’s electrical components. If you notice that your vehicle’s electronics are not working properly, take your vehicle to your local Speedy as soon as possible. This will avoid further complications, as you may be unable to re-start the vehicle.
