Age: If your battery is over 3-4 years old, it’s wise to have it tested, even if you haven’t noticed issues.

How to Test Your Car Battery

You can test your battery at home or have it done for free at most auto parts stores. At home, you’ll need a multimeter:

Make sure the car is off and has been sitting for at least an hour.
Set the multimeter to DC Volts (usually marked with a V and a wavy line or DC).
Place the red (positive) probe on the positive battery post and the black (negative) probe on the negative battery post.
Read the voltage:
- 12.6 volts or higher: Fully charged and good.
- 12.4 volts: About 75% charged.
- 12.2 volts: About 50% charged.
- 12.0 volts or lower: Needs charging, likely needs replacement soon.

A more thorough test, called a load test, measures how well the battery performs under load (like starting the car). This is best done at an auto parts store or repair shop.

Step-by-Step Guide to Replacing Your 2012 Kia Sorento Battery

Replacing a car battery is a straightforward DIY project. Safety first! Follow these steps carefully.

Safety Precautions: What You Need to Know

Car batteries contain sulfuric acid and can produce flammable gas. Always prioritize safety:

Wear Safety Gear: Safety glasses and gloves are a must.
Work in a Well-Ventilated Area: Avoid enclosed spaces.
No Sparks or Flames: Keep cigarettes, lighters, and sparks away from the battery.
Disconnect in Order: ALWAYS disconnect the negative (black) cable FIRST, then the positive (red) cable.
