Should I replace my Maserati's battery before it fails completely?

I've been going back and forth on this for a while now and I could really use some outside perspective from people who know these cars better than I do. My 2017 Quattroporte has been absolutely flawless since I bought it, but I've started noticing a few subtle signs that make me wonder if the battery is approaching the end of its life. The car still starts fine, no hesitation or slow cranking, but I've noticed that the stop-start system has become a bit unpredictable over the last month or so. Sometimes it works perfectly, other times it just Quick battery repair and replacement for Range Rover in Musaffah Gardens doesn't engage at all and I get a message saying battery charging, which seems odd because I drive the car almost every day and I take it on decent length journeys. I've also noticed that the infotainment system seems to take just a fraction of a second longer to boot up when I first start the car, and the ambient lighting doesn't seem quite as bright as it used to be. I know these Maseratis are extremely sensitive to voltage fluctuations because of all the complex electronics they have, and I've read that a failing battery can actually cause all sorts of weird issues with the gearbox and the engine management system that make you think something expensive is wrong when it's really just the battery. I've heard that on these cars, the transmission can start behaving strangely when the voltage drops below a certain level, which is one of the reasons I've been paying close attention. The thing is, I'm not sure whether I should just wait until the battery completely dies and then replace it, or if I should be proactive and get it replaced now before I end up stranded somewhere. I've seen people say that with modern luxury cars, it's actually better to replace the battery at the first sign of trouble because once it fails completely, it can cause all sorts of electrical glitches that are a nightmare to diagnose. But I also don't want to spend money unnecessarily if the battery still has a good year or two left in it. I've been looking around for a specialist who can properly test the battery and give me an honest opinion about its condition, because I don't trust the basic load test that most garages do, it doesn't really tell you the full story about the battery's health. I've read that you need to do a proper conductance test and check the internal resistance to really know what's going on, and that most places don't have the right equipment to do that properly. I've also heard that if you do need to replace it, you absolutely have to use the correct AGM battery with the right specifications and get it coded to the car's computer, otherwise the car won't charge it properly and you'll ruin the new battery within a year. I'm based near the Muwailih area and I've been trying to find a place that really understands these cars and can give me proper advice. I came across a mention of a Trusted Maserati transmission repair near Muwailih Commercial Sharjah, and it made me think that if they're good with transmissions, they probably have the right diagnostic equipment and technical knowledge to handle battery issues properly too. But I'm still not sure whether I should just bite the bullet and get it replaced, or wait and see if the symptoms get worse. Has anyone else been in this situation with their Maserati, where the battery was showing early signs of trouble but wasn't completely dead yet? Did you replace it straight away or did you wait until it failed completely, and how did that work out for you? I'd really appreciate some advice because I want to make the right decision for my car and avoid any unnecessary headaches down the road.
