Problem Statement

Learn how to check the battery health in a 2020-present Ford Explorer. Step-by-step guide with symptoms, diagnostic steps, and tools required.

Affected Component

Electrical

Estimated Time

1-2 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Always wear safety gloves and goggles when working with batteries.
•Disconnect the battery before performing any electrical repairs.

Symptoms

•Difficulty starting the engine
•Dim or flickering dashboard lights
•Electrical accessories malfunctioning
•Frequent need for jump-starts
•Slow cranking of the engine

Diagnostic Steps

1
Check for corrosion on battery terminals and cables, ensuring they are tight and clean.
2
Use a multimeter to measure battery voltage; it should read around 12.6 volts when fully charged.
3
Perform a load test using a battery load tester to check how the battery performs under a simulated load.
4
Use a hydrometer to check the specific gravity of the electrolyte in each cell (if applicable).
5
Use an OBD-II scanner to check for any battery-related error codes stored in the vehicle's computer.

Solution

💡 Expert Tip

For complex repairs like this, consider taking photos at each step. This helps if you need to reverse a step or consult with a mechanic. Also, keep all removed parts organized - you may need to reference them during reassembly.

Verification

After completing the repair, verify that the issue has been resolved:

✓Test the affected component to ensure it functions correctly
✓Check for any error codes or warning lights
✓Monitor the vehicle for a few days to ensure the issue does not recur

Prevention Tips

To prevent this issue from occurring again:

•Follow the manufacturer's recommended maintenance schedule
•Address warning signs early before they develop into major issues
•Use quality parts and fluids recommended for your vehicle
•Keep detailed records of all repairs and maintenance

Tools & Equipment Required

•Multimeter
•Battery load tester
•Hydrometer
•Safety gloves
•Safety goggles

Parts Required

•Battery cleaner (optional)
•New battery (if replacement is necessary)

Diagnostic Steps

Solution

1. Preparation

Tools Required:
- Multimeter
- Battery load tester
- Hydrometer (if applicable)
- Safety gloves and goggles
Make sure the vehicle is off and parked on a flat surface.

2. Visual Inspection

Inspect the battery terminals for corrosion (white, ashy substance).
Clean terminals using a wire brush and a solution of baking soda and water if corrosion is present.
Ensure connections are tight; loosen and re-tighten as necessary.

3. Measure Voltage

Connect the multimeter leads: red to the positive terminal and black to the negative terminal.
Read the voltage; a healthy battery should show around 12.6 volts. If the reading is below 12.4 volts, the battery may be weak.

4. Load Test

Connect the battery load tester's clamps to the battery terminals.
Follow the tester's instructions to apply a load equivalent to half the battery's CCA (Cold Cranking Amps) rating for 15 seconds.
Observe the voltage; it should not drop below 9.6 volts under load.

5. Check Specific Gravity (if applicable)

Use the hydrometer to draw electrolyte from each cell of the battery.
Check the color of the float; it should indicate the specific gravity. A range of 1.265 to 1.300 is generally considered fully charged.

6. Scan for Error Codes

Connect the OBD-II scanner to the vehicle’s diagnostic port.
Check for any battery or charging system-related codes. Clear any codes if necessary.
