Hi all!

I'm just after a bit of advice. My DB7 has been laid up in the garage since October due to work and the awful weather up north. I had it on a trickle charger and conditioner which has always worked fine. However, this time it seems it hasn't done its job properly.

As is typical with these things, I removed the charger as normal, let the boot close, went to start up the car and then realised something was up. As the boot is power operated I now can't get back in to recharge the battery or even jump start it.

Can anybody help?! I should realised when the window didn't drop properly when I open the drivers door but as usual I was too excited to get my car out and make the most of a sunny morning (which has now turned cloudy...).

Thanks in advance (I also feel like a bit of a pillock).

I might be missing the point here but there is a lock under the Aston badge (it always sticks up for me after I open the boot mad ). Can you not just stick your key in there? I know they're sometimes a bit sticky because they're never used but a bit of WD40 should do the trick.

That's somewhat annoying!
I've run our battery conditioner on a V8V via the socket in the car rather than the boot one. The conditioner appears to do the business fine without any issue.
Assuming a similar arrangement on a DB7 (and that your conditioner conects via a regular cigarette lighter plug), if you plug your conditioner into the socket in the car it's probable it will give sufficient juice to open the boot.
I don't believe that there is any risk associated with this as both the in-car and boot mounted sockets would have protection (fuses) of a rating appropriate for the wiring.

Failing that, I'm out of ideas!
Good luck

This ^^

However don't twist too hard as you could shear the key!! If you haven't used it before, free it off...

no jump points at the front on a DB7?

Cheers for the advice. I've had the car since June and had no idea there was a lock under the badge. Apologies for being a complete tool.

I got the car started and took it out for a good run, all seems OK now but I'm heading out to buy a new charger for it.

I'd check the battery too, if it was flat for a long time it might not be 100% anymore.

Quite possibly.

On the 12v lead acid batteries, best not to let it drop below a terminal voltage of 10.5. If it had gone below about 7 you would not have been able to recharge it smile

I'd change the battery and screw messing about checking it. As stated a flat battery is rarely much cop afterwards.
Dying batteries are a royal pain and in my experience (not with an Aston) can have very undesirable consequences with imobilisers etc which will far exceed the cost of a battery.

Cheers for the advice everybody. A new battery is on order as I expect the plates have now furred up inside.

It was nice to get the car out whilst it was dry, I miss driving it when the weather is wet and miserable!
