Where to find Aston battery specialists near Za'abeel?

I've been driving my DB9 for about three years now and absolutely love it, but recently I've started noticing that the battery seems to be struggling, especially after the car sits for a couple of days. The past few mornings I've been getting that slow, labored crank that makes you hold your breath and pray it actually turns over, and I know I'm probably on borrowed time at this point. The thing that's making this complicated is that I work in Za'abeel and live closer to Business Bay, so I don't really have time to drive all the way out to the industrial areas during the week to get this sorted. I've been doing some research trying to find certified Aston Martin battery dealers in Za'abeel and Business Bay because it would be so much easier to find someone nearby who can come to me or at least isn't too far out of the way. I'm particularly nervous about getting this right because I've read that Aston Martins can be really picky about battery replacements, something about the intelligent charging system needing to be reset properly, and I definitely don't want to end up with warning lights or electrical issues because someone didn't know what they were doing. Has anyone had a good experience with a mobile service or a garage around these areas that actually knows how to handle the electronics on these cars properly? I'm willing to pay a bit more for peace of mind, I just don't want to end up with more problems than I started with because I'm really not looking forward to dealing with electrical gremlins later on.
