Battery Boost in Ottawa: What to Do and Who to Call

Dead Battery? Here's What Actually Works

Ottawa winters are brutal on car batteries. When it's -20°C and your car won't start, a battery has lost about 60% of its cranking power. If it's more than 3 years old, the cold might finish it off.

Here's what to do, in order:

1. Confirm it's the battery

Turn the key (or press the start button). If you hear a rapid clicking sound or the engine cranks slowly and dies, it's almost certainly the battery. If you hear nothing at all — no lights, no click — it could be the battery, the alternator, or a bad connection. A boost will tell you which.

2. Try a jump start (if you have cables)

If you have jumper cables and a second car:

  • Park the working car close enough that the cables reach both batteries (don't let the cars touch)
  • Turn off both cars
  • Red clamp to dead battery's positive (+) terminal
  • Red clamp to good battery's positive (+) terminal
  • Black clamp to good battery's negative (-) terminal
  • Black clamp to an unpainted metal surface on the dead car (not the battery — this prevents sparks near the battery)
  • Start the good car, let it run 2–3 minutes
  • Try starting the dead car
  • If it starts, remove cables in reverse order and drive for at least 20 minutes to recharge

3. Call for a battery boost if that doesn't work

If you don't have cables, or the jump start doesn't work, you need professional help. A boost from a roadside service takes about 5 minutes once they arrive.

Call Most Valuable Towing at 613-262-6912. We'll come to you anywhere in Ottawa with a commercial-grade jump pack that works on cars, trucks, SUVs, and even box trucks. Available 24/7 — including those -30°C mornings.

What if the boost doesn't work?

If the car starts with a boost but dies again shortly after, the problem isn't the battery — it's the alternator. You need a tow to a mechanic. If the car won't start even with a professional boost, the battery is completely dead and needs to be replaced. We can tow you to your mechanic or a shop that sells batteries.

Prevent it from happening again

  • Replace your battery every 4–5 years — don't wait for it to die
  • In winter, plug in your block heater if you have one
  • Park indoors or use a battery blanket when it drops below -20°C
  • Get your battery tested at any auto parts store — it's free and takes 2 minutes
  • Keep jumper cables in your trunk — and know how to use them

Why our boost service is different

Most tow companies use a basic jump pack. We use commercial-grade boost equipment that delivers enough amps to start diesel trucks and heavy equipment — so your car, SUV, or pickup is no problem. Our drivers test your battery after the boost and can tell you if it's time for a replacement or if you just left a light on. No upsell, just honest advice.

Save 613-262-6912. When your battery dies in an Ottawa winter, you'll be glad you did.

Frequently Asked Questions

Quick answers

How long does a battery boost take?

Usually five to ten minutes once the tech arrives. If the car starts but won't stay running after a short drive, the battery isn't holding a charge and needs replacing, not another boost.

Does a battery boost work at -30°C?

Yes. We carry both jumper cables and portable jump-packs built for extreme cold. The battery may take a few extra minutes to accept a charge at that temperature, but we can usually get you started.

How do I know if my battery needs replacing or just a boost?

If the car starts after a boost and runs normally for several days, the battery is likely fine. If it dies again within hours or won't hold a charge overnight, it needs replacing. A free voltage test at any Ottawa auto-parts shop will confirm it.
