why does my Honda CR-V Fifth Generation (2017-2022) battery keep dying

Solution

1. Preparation

• Gather tools such as an OBD-II scanner, multimeter, and basic hand tools.
• Ensure safety gear is worn, including gloves and goggles.
• Disconnect the negative battery terminal.

2. Battery Replacement (if faulty)

1. Remove Old Battery:

   • Unscrew the battery hold-down bracket.
   • Carefully lift the battery out of the tray.

2. Clean Battery Tray and Terminals:

   • Use a wire brush to clean corrosion from the terminals and battery tray.
   • Apply a terminal protector spray.

3. Install New Battery:

   • Place the new battery in the tray.
   • Secure it with the hold-down bracket.
   • Reconnect the positive terminal first, followed by the negative terminal.

3. Repair Electrical Issues (if applicable)

1. Identify Faulty Components:

   • Inspect wiring harnesses for frays or shorts.
   • Test and replace any defective relays or fuses.

2. Fix Parasitic Draw:

   • Identify the circuit causing the draw by pulling fuses one at a time.
   • Repair or replace the component causing excessive current draw.

4. Test Charging System

1. Check Alternator Output:
   • Reconnect the negative battery terminal and start the engine.
   • Use the multimeter to check voltage at the battery while the engine is running.
   • If the voltage is outside the specified range, replace the alternator.
