How to Know If Your Car Battery Needs to Be Replaced

In many cases, a failing battery will give off some telltale signs that it’s reaching the end of its useful life. If you spot any of these signs, make battery replacement a priority as soon as possible. Here’s how to know if your car battery needs to be replaced:

  • Dimming headlights
  • Increased need for engine revs or jumpstarts to start your vehicle
  • Noticeable fluctuations in vehicle power
  • The engine lags or struggles when you turn the key/push the button

How to Test a Car Battery

There are several ways to test a car battery, but the most common are the headlight test and the use of a digital multimeter. Either of these options gives you dependable results that tell you if your battery needs to be replaced. This is how to test a car battery using these two methods:

The Headlight Test

  1. Turn on the engine and headlights while keeping the car in park.
  2. Rev the engine and check if the brightness of the headlights changes.
  3. If the headlights are noticeably brighter, the battery current is not strong enough to keep the lights at normal brightness when the car is idling.
  4. Bring your car into our service center for more testing and a potential battery replacement.

With a Digital Multimeter

  1. Set the voltmeter to 20 DC volts.
  2. Pop the hood, and touch the negative black terminal with the negative meter probe, which is also black.
  3. Touch the red positive terminal with the red positive meter probe.
  4. Switch on the headlights and check the voltmeter reading.
  5. 12.5 volts or higher means your battery is fully charged; 12.3 volts means it’s around 75% charged; and 11.8 volts or lower means you have a charge of 25% or less.

How Much is a Replacement Car Battery?

If you’ve discovered you need a new battery, you’re likely wondering about cost. So, how much is a replacement car battery? Expect to spend between $75 to $200 for a new car battery. And how much is a replacement car battery for an EV or hybrid? Because of the bigger workload these batteries are tasked with, EV and hybrid batteries come with a significantly higher price tag.
