Disconnect and Reconnect the Battery

Last updated: June 12, 2026

Disconnecting the 12 V battery on your Genesis GV70 (JK1, 2020–2024) — for a new battery, winter storage, or work near the airbags — is straightforward once you know it lives in the boot, not under the bonnet.

Find the Battery First

The 12 V battery is in the luggage compartment (boot), under the trim. Note your radio presets and user settings before you start.

Disconnecting Safely

1. Turn the ignition off and make sure all electrical consumers are off.
2. Expose the battery in the boot and disconnect the negative (−) terminal first, then the positive.
3. Working near airbags or seat-belt pretensioners? Wait a few minutes after disconnecting.

Reconnecting and Re-initialising

Reconnect positive first, then negative. The GV70 then needs a few items relearned:

• Power windows — re-initialise one-touch (see our window initialisation guide).
• Powered tailgate and sunroof may need re-initialising on first use.
• Tyre pressure monitor — drive to re-store the pressures.
• Re-enter the clock and presets.

If Something Isn’t Right Afterwards

• Warning lights often clear after a short drive.
• A persistent light stores a code — look it up on autodtcs.com.
• Fit a like-for-like battery — the correct type and rating for the car’s electronics.
