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

Frequently Asked Questions

How much does an alternator replacement cost in London? +
Alternator replacement typically costs $400-$800 including parts and labor. Premium or European vehicle alternators can cost $600-$1,200+ due to more complex installations.
How do I know if my battery or alternator is the problem? +
If the car won't start but the lights work, it's likely the starter. If the battery keeps dying, a professional load test will determine if the battery itself is weak or if the alternator isn't charging it properly.
How long does a car battery last in Canada? +
In Canadian climates with extreme temperature swings, car batteries typically last 3 to 5 years. Harsh winters significantly accelerate battery degradation.
Can a parasitic drain kill my battery overnight? +
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.
