As a car owner in Singapore, you understand the importance of keeping your vehicle in optimal condition. A healthy car battery is essential to ensure smooth functioning and avoid unexpected breakdowns.

In this guide, we will walk you through a simple DIY process to check the condition of your car battery, customized for our Singaporean audience.


What You’ll Need

Before we start, gather the following tools and materials:

  1. A pair of gloves
  2. Safety glasses
  3. A digital multimeter
  4. Battery terminal cleaner (if required)
  5. A clean, dry cloth
  6. A torch (if working in low-light conditions)


Step 1: Safety First

  • Always wear gloves and safety glasses to protect your hands and eyes from any corrosive battery acid or debris.
  • Ensure the car engine is turned off and the key is removed from the ignition.
  • Make sure your vehicle is parked on a flat surface with the parking brake engaged.


Step 2: Locate the Battery

  • Open the car bonnet and secure it in place.
  • Locate the battery, which is typically a rectangular box with two cables attached to it.
  • Consult your car owner’s manual if you are unsure about the battery location.


Step 3: Inspect the Battery

  • Check the battery casing for any signs of damage or leaks.
  • Look for any signs of corrosion or dirt on the battery terminals.
  • If the terminals are dirty, use the battery terminal steel brush to remove the corrosion or dirt.
  • Wipe down the battery with a clean, dry cloth.


Step 4: Check the Battery Voltage

  • Set the digital multimeter to measure DC voltage.
  • Attach the red (positive) probe to the positive battery terminal, marked with a “+” sign or red cover.
  • Attach the black (negative) probe to the negative battery terminal, marked with a “-” sign or black cover.
  • Check the voltage reading on the multimeter display.
  • A healthy battery should have a voltage reading between 12.4V and 12.7V when the engine is off.
  • If the voltage is below 12.4V, your battery may be discharged or weak.


Step 5: Perform a Load Test to Determine Alternator Charging for a 12V Mechanical Battery (Optional)

  • If your multimeter has a built-in load tester, you can perform a load test to check the battery’s ability to provide power under stress.
  • With the multimeter probes still connected, switch to the load test setting.
  • Turn on the headlights and air-conditioning for about 15 seconds to determine the alternator charging.
  • A good battery would have a healthy charging range between 13.6V to 14.5V during the load test.


Step 6: Interpreting Results and Next Steps

  • If your battery voltage is within the healthy range and passes the load test, your battery is in good condition.
  • If the voltage is low, you may need to recharge the battery or consider replacing it if it’s old or damaged.
  • If you are unsure about your battery’s health or if it fails the load test, consult a professional mechanic for further assistance.
