Aston Martin Vanquish Flat Battery

We don't have a garage so can't leave the car on the trickle charger so the battery keeps going flat. It is an Aston Martin Vanquish 2004. When this happens, the boot locks so we can't access the battery or connect the trickle charger. Apparently there is a way of accessing the boot by removing the rear seats but we are not sure how to do this and obviously don't want to damage the car. Any suggestions?

There's a relatively easy answer.
You were told correctly that you have to take out the back seats.
This is easy.
Between the lower cushion parts of the back seats is a small, cucumber size piece of leather trim, this you simply pull out.
Under this are some manually screwed in bolts, a bit like the dials on your old car radio, take them out, then juggle out the lower cushions.
On fitting they're kind of pushed under the side panels (under the window) so you have to pull hard.
Next there are a couple of bolts holding the backrest in place, these are at the bottom of the backrest, remove.
You only need to remove the RH backrest. (Right hand means on the left if you're facing backwards).
After these are out all that holds the backrest is a spring 'jaw'.
To explain how this works, let me explain something.
Before the seats were in, if you were fitting the backrest and you were kneeling in the car, looking at the metal (body) backrest support you would see a 2" x 2" hole in the Body.
On the back of your seat panel is a large metal clip, it works a bit like a big paper clip.
This slides upwards into the metal body (hole) behind to fit, down to take the backrest out, so slide the seat panel downwards.
Now the seats are out.
Here you will see a handle like on a car bonnet release. Pull it, voila.
I had a similar charging availability problem to yours last year, all I did was about once a week, parked the car on the drive (overnight at least), put it on charge, gathered the cable to the right hand rear boot corner where there's plently of clearance then locked the boot.
You won't damage the wire, just trap it in the seal.
My battery never went flat once.
If you haven't got a drive do it at a friends.
Good luck.

Just an addendum if you need to access or change the battery. On the Vanquish S (left hand drive) you need to take out the rear passenger seat bottom and back. 1) Remove the small divider pad between the two seat bottoms-it is a tight press fit - maneuver froward and up to remove, 2) Undo the right knob in between the two seat bottom seats then wrestle the right passenger seat bottom out - it is a tight fit and is tucked under the arm rest. 3) Undo the 2 Bolts (10mm) that attach the seat back to the frame .4) Slide the seat back up un-clipping it from the retainer at the top of the seat back. 5) you will see an aluminum plate with 8 bolts and a flat harness of wires running diagonally across it.Note the positioning of the wire harness for reinstalling as in the wrong position they could get pinched iand prevent the seat bottom from fitting properly.6) Undo the 8 bolts and slip the aluminum panel out to have access to the battery. 7) Turn the Battery Switch 'Off" before removing the battery clamps, 8) There is a clamping bracket holding the battery in place with 3 bolts holding it in place. You are now able to carefully remove the battery-it is heavy and a close fit. When reassembling , it can be a little fiddly and I found it helpful to have a second set of eyes and hands.

First suggestion is if the battery needs to be charged all the time get it checked and also check ur charging circuit and find if there is a battery drain.

    The Vanquish is infamous for short battery life and high current drain when turned off which is why it comes with a trickle charger and an accessory input in the trunk-if the car is going to sit more than a week or so plug it in.-

How do I find and access a 2002 Aston Martin vanquish battery. Mine is completely dead and needs to be charged.

IIRC it is in the trunk/boot. However, there is a BATTERY + post in the engine bay so you don't need to pull the trunk/boot carpet up to charge the battery.

Location should be available from your Hand Book.

It is usually under a black plastic cover marked + in a circle. You attach the Positive+ clamp here and the Negative - clamp to a convenient metal engine component...such as a bracket.

WARNING: Modern vehicles are full of electronics. When charging a battery you must either remove the battery from the vehicle or use a low Amp charger set to 2 to 10 Amp for about 6 to 8 hours.

Failure to follow this proceedure will often result in electronic component failure of the 6 to 10 computers (ECU's.) placed around the car. Any of which can cost $1000.00 and up to replace.

I have just re ECU'd a Mercedes for $5,400.00 for a similar mishap !

Many European vehicles are equipped with a ballistic battery disconnect feature ....that disconnects the battery + cable in the event of a wreck. It is a fat bright RED component and must be handled with care.

You will also find some feature on the car will not work after charging the battery due to lost memory. ..such as window express down and radio pre-sets or activation code.

If you feel unable to reset these feature you need to go to the dealership. There are very few shop that are equiped to work on these machines.....and Aston is not forth coming with test information.

Where is battery located

I'm actually surprised at the lack of information about that vehicle. i would suggest looking in the trunk... as it is a rear engine from what i can find out. the trunk is in fact in the front.

Have an Aston Martin vanquish 2007. Battery is dead and can't use remote to open the car. The key does nt work either (both sets).

this works for other cars
can you jack up and support the car and hook a jumper cable to the positive terminal on the starter? If so you can hook up the jumper cables to a good battery and a ground on the car. This should give you the power needed to open the doors.
