Tools & Parts Needed (DIY)
Always use the correct tools for your specific model. Using wrong-sized screwdrivers can strip screws and cause additional damage.
Step-by-Step DIY Guide
Follow these steps carefully. Take photos at each stage for reference during reassembly.
Turn off and locate the battery
Turn off your Hyundai Tucson and remove the key. Open the hood and locate the battery — usually in the engine bay, though some models mount it in the trunk or under the rear seat.
Disconnect the negative terminal first
Use a 10 mm wrench to loosen the negative (-) terminal clamp and pull it off the post. Tuck it away from the battery. Then disconnect the positive (+) terminal.
Always disconnect negative first. If a wrench touches the positive terminal and any ground point simultaneously, it will create a dangerous short circuit with sparks and potential battery explosion.
Remove the battery
Remove the battery hold-down clamp (usually a bracket with a bolt). Lift the battery straight out — it weighs 30–50 lbs. Use both hands and keep it level to prevent acid spills.
Install the new battery
Place the new battery in the tray with the positive and negative posts matching the original orientation. Reinstall the hold-down clamp. Connect the positive terminal first, then the negative. Tighten clamps snugly.
Test and reset
Start the engine and verify all electronics work. You may need to reset the clock, radio presets, and window auto-up/down. If the check engine light appears, it usually clears after a few drive cycles.
