Battery FAQ
Quick answers London drivers ask about batteries and no‑start problems.
How long does a car battery usually last in Ontario?
Most batteries last about 3–5 years depending on driving habits, heat/cold exposure, and electrical load. Regular testing helps you avoid surprise failures.
My car clicks but won’t start — is it always the battery?
Not always. Clicking can be a weak battery, poor connections, a failing starter, or a charging issue. We test the full starting/charging system to pinpoint the cause.
Can you test my alternator if the battery is dead?
Yes. We can test charging output and the condition of the battery and cables. If needed, we’ll charge the battery enough to run accurate diagnostics.
Do you install AGM or special batteries?
Yes. Many newer vehicles require AGM or specific ratings. We’ll match the correct battery spec for your make/model.
Why does my battery keep dying?
Common causes include parasitic drain, a weak alternator, corroded connections, or short-trip driving that never fully recharges the battery. We can diagnose the root cause.
