Car Battery Replacement Service


Your car’s battery is responsible for providing power to your ignition system, headlights, instrument panel, air conditioning system and more. Without a healthy battery, your vehicle won’t get very far! To keep your vehicle in good condition, follow these guidelines around car battery replacement.

How Often to Replace a Car Battery

Over time, the battery’s charge capacity diminishes, and it struggles more to hold a charge. This means the battery won’t provide enough power to start the vehicle or run the electrical system effectively.

The life expectancy of most car batteries is between three and five years, depending on usage and the manufacturer. Once your battery reaches this age, you’ll need to pay more attention to how it operates to know when to replace it.

Signs You Need to Replace a Car Battery

If you notice any of the following symptoms and/or your battery is more than three years old, it needs to be recharged or replaced:

  • The battery warning light is on.
  • The engine dies quickly after starting or won’t start at all.
  • The vehicle needs frequent jump starts.
  • The headlights and interior lights are dimming or flickering.

To manage these symptoms, you can try recharging the battery before fully replacing it. Your car’s internal charging system powers the battery when you drive, but sometimes, driving around isn’t enough. Use a battery charger or booster pack or jump-start your vehicle to bring your battery up to 12.4 volts or higher.

If you notice any swelling, cracks, corrosion, or leaking from your battery during a visual inspection, don’t recharge it. In these cases, go straight to replacing your battery.

Choosing a Replacement Battery

Getting the right battery for your car is crucial to the replacement process. There are three common car battery types:

  • Lead-acid: Most common in passenger vehicles because of the affordable price and easy installation.
  • AGM: Last longer than lead-acid batteries but are more expensive. You can upgrade to an AGM battery from a lead-acid one, but you can’t downgrade to lead-acid battery if your car originally had an AGM battery.
  • Lithium: Primarily used in electric vehicles.

Check your owner’s manual for information on what battery to pick in terms of size, voltage, and terminal placements.

Car Battery Replacement Cost

Battery prices depend on the size and cold cranking amps required for your vehicle. Prices for batteries vary; however, expect to pay a few hundred dollars depending on your vehicle model.

If you follow the instructions carefully, replacing your own car battery is a fairly simple task. Check out this guide to do your own car battery replacement service. If your battery looks difficult to remove/replace, take your vehicle to a NAPA AUTOPRO service centre to have it assessed by a professional.

Battery Maintenance Tips

To help your battery last as long as possible, follow these maintenance tips:

  • Drive your car at least once every three to four days.
  • Clean the battery once every four to six months.
  • Test the battery every six months with a multimeter.
  • Avoid storing your car/battery in extreme temperatures (ideal battery storing temperature is 27°C.)

We understand that the last point may sound confusing: temperatures routinely drop much lower than that in the Canadian winter. But if you’re able to store your vehicle in a garage or use a battery warmer on it overnight, you may be able to increase the longevity of your battery.
