1Battery Lifespan
Most car batteries last 3-5 years in Canadian climates. Extreme cold and heat shorten lifespan. If your battery is over 4 years old, have it tested annually.
2Warning Signs
Slow cranking when starting, dimming headlights, electrical issues, and the battery warning light are all signs of a failing battery.
- Engine cranks slowly or struggles to start
- Headlights dim when idling
- Electrical accessories behave erratically
- Battery is swollen or leaking
3Terminal Maintenance
Check battery terminals for white or greenish corrosion. Clean with a wire brush and baking soda/water solution. Ensure connections are tight.
Pro Tip: Always disconnect the negative (black) terminal first and reconnect it last to avoid sparks.
Key Takeaways
- 1Replace batteries every 3-5 years
- 2Test annually after 4 years
