Batteries and electrical

The first minus twenty morning of the year finds every weak battery in Ottawa. We test the battery, the alternator and the starter together, because a new battery on a bad alternator just goes flat again.

Signs your battery or charging system is going

  • The engine cranks slowly on cold mornings.
  • You needed a boost, and it happened again.
  • The battery light comes on while driving.
  • Headlights dim at idle and brighten when you rev.
  • The car is dead after sitting for a few days.
  • The battery is five years old or more.

How we test

We load test the battery to see how it holds up under the kind of draw a cold start puts on it. We check the alternator's output at idle and under load, and we check the starter's current draw. We clean and tighten the terminals and check the grounds.

If a battery goes flat while the car is parked, something is drawing power with the key off. We measure the drain and pull fuses one circuit at a time until we find it. Aftermarket remote starters, dash cams and trailer wiring are common causes.

Replacement

We fit a battery with the right size and cold cranking rating for your car. Many newer cars with start stop systems need an AGM battery, and some need the new battery registered to the car's computer so it charges correctly. We handle that.

Questions about
batteries and electrical

How long does a car battery last in Ottawa?

Usually four to six years. Cold winters and hot summers are both hard on batteries, and short trips never let them fully recharge.

Why does my battery keep dying?

Either the battery is worn out, the alternator is not charging it, or something is drawing power while the car is off. We test all three.

Do you replace alternators and starters?

Yes, after testing confirms that is the problem.

My car won’t start. What should I do?

Call Tow Kings at (613) 276-4714, or call us at (613) 745-0004. We will get the car in and find out why.
