Exclusive Bentley battery replacement in Emirates Hills – where do you take yours?

I'm in a bit of a situation with my Continental GT. It's been parked up for a few weeks while I was traveling, and when I went to start it this morning, I just got that sluggish crank that makes your heart sink – it eventually fired up, but I know that's a warning sign I can't ignore. I've been reading up on it, and apparently in the Dubai heat, a Bentley battery typically only lasts around 2 to 4 years, which is shorter than in cooler climates because the extreme heat accelerates the chemical reactions inside . The problem is, I don't trust just any garage with this car; I've heard too many stories about sensitive electronics and control modules throwing faults if a battery change isn't done properly . I'm specifically looking for an Exclusive Bentley battery replacement in Emirates Hills, ideally from a workshop that understands these cars and uses genuine or OEM-spec AGM batteries for the start-stop system . I've seen a few places in Al Quoz that specialize in Bentley, but I'd rather not drive across town with a dodgy battery if I can help it. Has anyone here used a good specialist for their Bentley in the Emirates Hills area recently? Any recommendations would be massively appreciated.
