A weak battery can leave you stuck when you least expect it. The good news is that there are often warning signs before a battery fails.

One common sign is a slow engine start. If your vehicle takes longer than usual to start, your battery may be getting weak.

You may also hear a clicking sound when you try to start the vehicle. This can happen when the battery does not have enough power to start the engine.

Other signs of a weak battery include:

  • Dim headlights
  • Interior lights that look weak
  • Electrical issues
  • A battery warning light
  • Trouble starting after the vehicle sits
  • Corrosion around the battery terminals

Weather can also affect your battery. Extreme heat and cold can both make battery problems show up faster. That is why battery checks are helpful before summer and winter.

If your battery is several years old, it may be smart to have it tested even if the vehicle still starts.

A battery test can help you know if your battery is still healthy or if replacement may be needed soon.

If your vehicle is starting slower than normal, schedule a battery test at Dave Sinclair Buick GMC in St. Louis. Our service team can test your battery and charging system and help you avoid getting stuck.
