Auto Electrical Tips

  • Have your battery tested before every winter—cold weather dramatically reduces battery capacity
  • Keep battery terminal connections clean and tight using a wire brush and anti-corrosion spray
  • If your vehicle sits for extended periods, use a battery tender to maintain the charge
  • Never attempt to jump-start a cracked or leaking battery—it could explode
  • Replace your battery every 4 to 5 years as preventative maintenance
  • If you notice a burning electrical smell, disconnect the battery and get a professional diagnosis immediately

In Canadian climates with extreme temperature swings, car batteries typically last 3 to 5 years. Harsh winters significantly accelerate battery degradation.

Yes, a parasitic draw from a faulty module, interior light, or aftermarket accessory staying on can drain your battery overnight. A mechanic can perform a parasitic draw test to isolate the circuit causing the problem.
