Reliable mobile battery replacement in Dubai for a Cadillac Escalade?

I've got a 2020 Cadillac Escalade that's been a dream to drive, but the battery is clearly on its last legs, especially with the UAE heat. I had a bit of a scare last week when it almost didn't start, and with the summer coming, I want to get it replaced before I end up stranded. I've had bad experiences with those random mobile guys who just show up with a basic multimeter and a generic battery, and don't even bother checking the alternator or doing the proper diagnostics. I'm looking for a professional service that stocks a high-quality AGM battery that can handle the heat and the electronics in this truck. I stumbled across a website that claims to be a top battery supplier in UAE and they have 24/7 availability with a quick response time, which is exactly what I need since I can't afford to take time off work to sit at a garage. They also mention that they do a proper alternator test and even register the battery for vehicles that need it, which sounds like the level of service I'm after. Has anyone here used them for a replacement on a full-size SUV like the Escalade? I'd really like to know if they actually show up with the right tools and do a thorough job, or if it's just another quick swap and go operation.
