When to Change Your Car Battery

When to Change Your Car Battery
Close-up of a car battery

A flat battery is one of the most common reasons a car will not start — and it usually happens at the worst possible time, on a cold morning or just as you are about to leave for work. The good news is that a failing battery almost always gives you warning signs first. Here is what to look out for, and when to change it.

Slow Engine Crank

If the engine turns over more slowly than usual when you turn the key or press the start button, your battery may be losing its charge. A healthy battery should turn the engine over briskly. If it sounds tired or laboured, get the battery tested.

Dim Lights and Weak Electrics

Headlights that look dim, a dashboard that seems dull, or electric windows that move slowly can all point to a battery that is no longer holding a proper charge. The same goes for a radio or heater fan that seems weaker than it used to be.

The Battery Warning Light

If the battery warning light comes on while you are driving, do not ignore it. It can mean the battery is not charging properly, and the car could stop. Have it checked as soon as you can.

How Old Is Your Battery?

Most car batteries last a few years, and they wear out gradually rather than all at once. Cold weather makes a weak battery worse, which is why so many batteries fail in winter. If your battery is several years old and you have noticed any of the signs above, it is probably time for a new one.

Swelling, Leaks or Corrosion

Take a look at the battery if you can do so safely. A swollen case, a leak, or white or blue crusty deposits around the terminals are all signs that the battery is coming to the end of its life and should be replaced.
