why does my Ram 1500 DT (2019-Present) battery die after a few days

Solution

1. Preparation

• Gather necessary tools and materials.
• Tools Required:
  • OBD-II scanner
  • Multimeter
  • Wrench set
  • Wire brush or battery cleaning tool
• Safety Warnings:
  • Disconnect the battery before working on electrical systems.
  • Wear safety goggles and gloves.

2. Clean Battery Terminals

• Disconnect the negative terminal first, followed by the positive terminal.
• Clean the battery terminals using a wire brush to remove any corrosion.
• Reconnect the positive terminal first, then the negative terminal.

3. Replace the Battery (if necessary)

• If the battery voltage is below 12.4 volts after charging, consider replacing the battery.
• Remove the battery hold-down bracket and disconnect the terminals.
• Install the new battery, ensuring it is securely placed and connected in the correct order (positive first, then negative).

4. Repair Electrical Drain

• If excessive current draw was identified, locate the source by removing fuses one at a time until the draw drops to a normal level (below 50 mA).
• Repair or replace any faulty components or circuits that are causing the parasitic draw.

5. Recheck and Test

• Once repairs are completed, recheck the battery voltage and current draw.
• Test drive the vehicle to ensure all electrical systems are functioning correctly.
