Testing and Replacing a Car Battery

To determine if your car battery is failing, you can perform a test using a multimeter. Follow these steps:

• Set the multimeter to measure DC voltage.
• Connect the red probe to the positive terminal and the black probe to the negative terminal of the battery.

Here’s what the voltage readings might indicate:

• 12.6 volts: Fully charged.
• 12.4 volts: 75% charged.
• 12.2 volts: 50% charged.
• 12 volts or less: Recharge or replace the battery.

If the battery needs replacing, here’s a quick guide to help you remove and install a new one:

• Tools needed:
• Wrench or socket set.
• Battery terminal cleaner.
• New battery.

Steps to replace the battery:

1. Disconnect the negative cable, then the positive cable.
2. Remove the battery hold-down clamp.
3. Lift out the old battery.
4. Clean the terminals and tray.
5. Install the new battery, securing it with the hold-down clamp.
6. Reconnect the positive cable, then the negative cable.

Remember to recycle the old battery at an authorized center.
