Disconnecting the 12 V battery on your Bentley Continental GT / GTC (393/394, 2011–2017) — for a new battery, winter storage, or work near the airbags — is straightforward once you know the battery is in the boot. These cars have a dual-battery setup (a main battery and a starter battery).
Find the Batteries First
The batteries are in the luggage compartment (boot), under the carpet and covers — a main battery and a starter battery. Note your radio presets and user settings before you start.
Disconnecting Safely
- Turn the ignition off and wait about 60 seconds.
- Remove the luggage-compartment carpet and the relevant battery cover.
- Disconnect the earth/negative (−) cable first, then the positive.
- Working near airbags or pretensioners? Wait a few minutes after disconnecting.
Reconnecting and Re-initialising
Reconnect positive first, then negative (don’t grease the terminals). The Continental then needs a few items settled:
- Power windows — re-initialise one-touch (hold the switch at the limits).
- Air suspension re-levels once driving.
- 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 like-for-like batteries of the correct type and rating.
Frequently Asked Questions

Which terminal first?
Negative/earth (−) off first, reconnect it last.
Why are there two batteries?
The Continental uses a main battery plus a dedicated starter battery; for normal work follow the cover labelling in the boot.
