What Are the Signs of a Failing Battery?

A car battery provides electrical energy to various systems in the vehicle. More importantly, it powers the starter, which then cranks the engine. Getting stranded in the middle of nowhere because of a dead car battery can be a harrowing experience. Not all car batteries will give you a sign before dying out, but luckily, most do.

What Causes a Dead Battery?

There are several reasons why your car battery is dying or not performing optimally, which include:

  • Corroded terminals or loose battery connections
  • Leaving your headlights on for an extended period
  • Extreme temperatures in winter or summer
  • The battery is too old
  • The battery is not charging while you drive
  • Parasitic draws on the battery due to faulty electrical systems
  • Taking too many short drives that don't allow sufficient battery recharging

Signs of a Dying Car Battery

The following are the top 5 most common signs of a battery in need of a thorough check or replacement:

Clicking Sound When You Turn the Key

A weak battery will send insufficient power to the starter when you try to start the engine. Reduced power supply to the starter will cause it to emit a clicking sound.

Dim Headlights

A dying battery cannot supply adequate power to all electrical systems, including the headlights. If you notice your lights are dimmer than usual, check your battery.

Slow Start or Sluggish Crank

A slow and dragging engine start is a sure sign that your battery is on its last legs. Your engine should crank up quickly unless outside temperatures have dipped dramatically. If not, the starter isn't getting insufficient power from the battery.

The battery is Swollen or Smells Funny

If your battery appears bloated and smells of rotten eggs, it is damaged beyond repair. This could result from a bad voltage regulator in the alternator, which results in overcharging, causing the battery to produce excess gas.

The Battery is Old

Car batteries can last up to five years. If your battery is a few years old, check it regularly to ensure it produces sufficient power and charges correctly. An old battery will fail sooner or later, so be vigilant to identify any signs of battery failure.

Wonderful, quick service. My low tire pressure light came on while driving to work downtown. I was able to make an appointment to drop off my car at lunch and picked it up after work. No charge for checking my tires and the employees were extremely friendly and efficient even though they were busy.
