Bentley Continental GT, GTC & Flying Spur have two batteries fitted in the boot of the car. The left one is the main systems battery, whilst the right is the starter battery.
It is quite common for the battery to drain over time. If the key is nearby, the car will ready itself for starting which can accentuate the problem. We recommend keeping a battery charger connected when the car is not going to be used for a long period of time.
If you find the main systems battery has gone flat, turning the key anticlockwise in the ignition barrel will engage the starter battery as a backup. Allowing you to start the car. It is recommended that the main systems battery is then charged/replaced as this function will drain the smaller starter battery very quickly.
Please note: We can only ship batteries to the UK and most EU destinations
