How to Tell if Your Car Battery is Dead or Needs a Charge

Is My Car Battery Really Dead?

A car that won’t start could point to a dead or drained battery, but how do you know for sure? Common signs include dim headlights, flickering dashboard lights, or a complete lack of response when you turn the key. Sometimes, the battery isn’t dead but just needs a quick charge. Before jumping to conclusions, it’s good to test and confirm the condition of your battery, so we put together this how-to guide on testing your car battery.

How to Test a Car Battery

Testing your car battery can help you determine if it’s dead, weak, or simply needs to be recharged. Below, we listed simple steps to testing a car battery:

Use a Multimeter

A multimeter measures voltage to help you identify if the battery is within the normal range (usually around 12.6 volts). Connect the positive (red) lead to the positive battery terminal and the negative (black) lead to the negative terminal. If the voltage reads below 12.2 volts, the battery could be weak or discharged. Below 10 volts often indicates a dead battery.

Load Testing

Don’t have a multimeter? Don’t worry, some auto parts stores offer free battery load tests. These tests simulate a car starting to determine if the battery can hold a charge under load. If you can’t find a local auto parts store that offers battery load tests, feel free to bring it to our service center in Aberdeen for a test today!

How to Jumpstart a Car Battery

If your battery is drained, jumpstarting your vehicle can potentially get you back on the road and to our service center in Aberdeen. Plan on jumpstarting your car battery? Follow these steps carefully:

  • Find a vehicle with a functional battery and jumper cables.
  • Park the donor car close to yours, ensuring the vehicles do not touch. Turn off both vehicles.
  • Connect the red jumper cable clamp to your battery’s positive terminal, then attach the other red clamp to the donor vehicle’s positive terminal.
  • Attach one black jumper cable clamp to the donor vehicle’s negative terminal. Finally, clip the other black clamp to an unpainted metal surface on your vehicle (like the engine block). This prevents sparking near your battery.
  • Start the donor car and then attempt to start your car.
  • Once your car starts, remove the cables in the reverse order of attachment.
  • Allow your engine to run for at least 15 minutes to recharge the battery. If your car doesn’t start after a jump, it’s likely time for a replacement.

Unable or too uncomfortable to jumpstart your own car battery? That’s okay! At AutoMaxx of Aberdeen, we know that DIY car maintenance isn’t everyone’s cup of tea. That’s why we have our service center in Aberdeen staffed by expert service technicians ready to have your car back up and running in no time.

How to Replace a Dead Car Battery

When your battery is beyond saving, replacement is straightforward but requires care. Here’s how to do it safely:

Gather Tools

You’ll need gloves, safety glasses, a socket wrench, and the correct replacement battery.

Disconnect the Battery

Always disconnect the negative cable (black) first, followed by the positive cable (red).

Remove the Battery

Unscrew any battery hold-down clamps, carefully lift out the battery, and place it on a flat surface.

Clean the Terminals

Use a battery terminal cleaner or wire brush to remove corrosion from the terminal clamps.

Install the New Battery

Place the replacement battery into the tray, reattach hold-down clamps, and connect the positive cable first, followed by the negative cable. Tighten both connections.
