why does my Ford Explorer Fifth Generation (2011-2019) battery die after sitting for a few days

Solution

1. Preparation

• Gather tools: multimeter, socket set, wire brush, battery terminal cleaner, and a battery charger.
• Ensure safety by wearing gloves and eye protection.

2. Disconnect the Battery

• Use a socket set to disconnect the negative terminal first, followed by the positive terminal.
• Ensure the battery is completely isolated.

3. Clean Terminals

• Use a wire brush and battery terminal cleaner to remove any corrosion from the battery terminals and connectors.
• Reconnect terminals securely after cleaning.

4. Test and Replace Battery

• If the battery voltage is below 12.4 volts after charging, consider replacing the battery.
• Use a battery tester to confirm the health of the battery. Replace if faulty.

5. Address Parasitic Draw

• With the multimeter set to measure current, connect it in series with the battery.
• Identify and disconnect fuses one at a time to isolate the circuit causing the draw.
• Repair or replace components associated with the circuit that is drawing excessive current.

6. Reconnect Battery

• Reconnect the positive terminal first, followed by the negative terminal.
• Ensure all connections are tight and secure.
