How to remove left side bentley battery with plastic wiring components/

Your battery( main starting battery as the car has two ) for this model is actually in the boot / trunk area on the left hand side hidden behind the trim. Once in the boot / trunk area - you will see the trim on the side has a plug socket on it - the battery is in there.....and that plug is where you attach the Bentley trickle charger.

replace/charge the battery

I have the same problem..Called dealer who told me yuu need to remove fuse panel above and disconnect all the wires on the positive lead bracket to be able to puch out of the way. Also there is a small metal tiedown on the panel in front of the battery panel that needs to be unscrewed to allow that panel to be moved forward a little...I will try the replacement this weekend and see how it goes...

The right hand battery supplies the engine cranking current and so is of a type that has a high cranking performance. This has an effect on the amp/hr performance. The left hand battery is of the deep draw kind able to supply a low current for a long time. Both batteries are only connected to each other and charging when the ignition is on. Manual charging would be one side at a time. If the left has gone flat switch on the ignition for a while before trying to crank. The car works fine with the same batteries in but not Bentley fine.

This is all the Bentley shows:

Hi, your battery( main starting battery as the car has two ) for this model is actually in the boot / trunk area on the left hand side hidden behind the trim. Once in the boot / trunk area - you will see the trim on the side has a plug socket on it - the battery is in there.....and that plug is where you attach the Bentley trickle charger too...

Both Batteries should be removed/disconnected and charged until they read 12.65 vdc with a DVOM.

with a trickle charger you can connect to any wire that goes to the battery as long as there is no circuit between the charger and the batt

The problem is most likely a faulty micro-switch, on the driver's side, under the tonneau cover. Unfortunately, it's impossible to accurately diagnose without a Bentley diagnostic computer, which will have to be performed at a Bentley dealer. As for the windows, the proper way to program the "one-touch" windows is to start with the front. Fully raise the front windows, release the switch, then hold it in the up position for a few seconds (you will hear the door module/window motor click) then fully lower the window, release the switch, and hold it in the down position for a few seconds. This will program the front windows, now do the same in the rear. Low battery voltage will usually cause the windows to lose their programming. You should have the vehicle attached to a Bentley battery tender whenever it is going to sit longer than a few days. The vehicle has 2 batteries, one only starts the car (right-side/start battery), the other (left-side/main battery) runs all of the electronics. Most people think, as long as the car starts, the battery is ok. That is not so with these vehicles. The car will start, even if the main battery is totally dead, or vice-versa. The installed battery tender attaches to the main battery, and comes with a neatly installed wiring harness, and a AGM battery approved battery tender. This will help avoid many different annoying electrical malfunctions.

There are 2 ways to do this. Remove the right rear seat cushion, and seatback. You will find a lever, that is the manual release for the trunk. If this is broken, use a large suction cup, and remove the taillights. This will provide access to the main battery, and start battery. Using an AGM approved charger, charge the main battery(Left-side-AGM) and start battery (Right-side-regular)
