1. Gather the necessary tools:
- Multimeter or voltmeter
- Wrench or socket set
- Safety goggles
- Gloves
2. Prepare the battery:
- Disconnect the battery terminals from the vehicle or device.
- Clean the battery terminals and posts to ensure good electrical contact.
3. Set the multimeter or voltmeter:
- Set the multimeter or voltmeter to measure DC voltage in the 0 to 20-volt range.
4. Connect the multimeter or voltmeter:
- Connect the positive lead of the multimeter or voltmeter to the positive terminal of the battery.
