Afternoon chaps, put new battery in my Vantage in October 2016, and it’s now dead. To be fair due largely to work commitments I only (shamefully) managed 1100 miles in the 12 months to October just gone.. it went flat after a three week period in September and October when I forgot to put the ctek on it... charged up ok, or so I thought.. two weeks ago I drove from Norwich to Sevenoaks and back to pick up an auntie... got home at three in the afternoon then next morning not enough battery to start it.. been on the trickle since, unplugged yesterday and fired first turn, left it unplugged overnight and it’s dead again this morning.. batteries either a gonner or I’ve got a serious drain going on... any thoughts fellas?
3 years isn't log but in the realms of possibly if the battery hasn't been used much. Worth a 5 Warranty year battery next time?
If you have a multimeter, you can test the battery. After running the car (or charging the battery) leave it connected for an hour and it should settle down to 12.6V or higher. No, 12.4V is not enough! Testing while the engine running should read 14.4V or similar but that's really checking your car's charging system. Cranking voltage should drop to about 9.6V. It's easier than most cars in Astons to do this...

This worked in my Vantage too, just don't crank too long, and you will need a spare pair of hands or feet to read the meter, as you can't do both.
Caveat emptor and all that...
Or just get someone else to check it, as above.
