I wonder if someone could help!

The battery is dead and a google search seems to bring up either 017 or 019 batteries. 019 is slightly taller.

Other PH articles suggested this

http://www.ebay.co.uk/itm/Aston-Martin-DB9-Coupe-5...

But the thread was drifting betweeen two cars so I can't be certain that this one for for a DB9 coupe.

If anyone could put me out of my mystery I would appreciate it!

Thank you

I have just replaced mine with a 019. It was the worst bit of car DIY that I have ever attempted...As the battery was flat I couldn't move the drivers seat forward to get to the rear seat.... Never again...

hello
,just done mine this aft, i have a late 2005 but think they are the same,bought this one on fleabay

H3 Varta Silver Heavy Duty Car Battery 100AH SIZE 017/019 (5 Years Warranty)
( 271728100058 ).cheap enough and delivered next day

its not a bad job to change but is bloody heavy!!!,

move the seat all the way forward, remove the lower part of the rear seat, its velcroed and just pulls up, theres another small panel at the base of the backrest just pulls off.

this reveals the top plate which is secured by 8mm head bolts, 3 across the back , 3 on the front edge 2 down either side.

once the bolts are removed you can lift this plate out carefully ( the edges are quite sharp and its a tight fit).

now you can see the battery and the cut off switch/clamp assy behind it.take a couple of pics so you get things back exactly as.

disconnect the battery breather (its a small plastic elbow with a pipe attached, it just pulls out of the battery).

disconnect battery terminals -ve ( earth) first, then + , these use a 13mm headed clamp bolt just slacken it off dont take the nut off, a twist and pull should get them off ( if your car has the back up battery alarm the manual says to switch the ignition on then off and disconnect within 10 seconds , this should prevent the alarm sounding)

the manual says "remove the battery clamp" this is part of the battery disconnect assy two legs run in slots down to the base of the battery the end of these legs forms the clamp.the idea is to remove the two 10mm headed nuts and lift the disconnect assy up to free the battery, well you`ve got no chance unless all the wiring is removed from the disconnect unit, not something i fancied at all!, just remove the two bolts that hold the disconnect unit down and ease it up a little bit maybe 10mm.
The front and sides of the battery are surrounded by an alloy box , lift the carpet at the front edge and remove 3x 10mm headed nuts , the box goes around the sides of the battery and theres 2 more 10mm nuts round by the disconnect unit , remove those , now the battery box can be lifted up and out or up to clear the studs at the front edge unit and forward a bit your choice, this releases the battery from the clamps.

Its time to lug the old one out, take your time ,plan the lift , put some protection on the back side of the drivers seat.

refit is reverse but when connecting its + first then -. the terminals may need "seating" a few gentle taps with a hammer shaft should do the trick.

One thing i noticed was the + cable was hard against the inside of the alloy box, twistng the terminal slightly clockwise on refit moved it away slightly.

because the battery has been disconnected its quite possible that the various ecu`s for engine and transmission will have lost some stored data, this is returned by driving the car , the values will be "relearned" but it may drive a bit differently until then.

Like I said...Never again. Try doing that with the drivers seat all the way back....

It must of been a s*d to do with the seat back!!, if you find yourself in a similar position to speculatore and you have another vehicle or a good battery and some jump leads follow "Electrical start from another vehicle" in the handbook which involves connecting to the "jump start terminal(+) under the bonnet and - to alternator bracket, this will power the seats (you might have to switch ignition on). you dont have to try and start engine if you dont want to.
