2016 XC90 T6, bought it in 03/2016. Does anyone know when the battery should be replaced? I have not noticed any problem yet, just thinking it's about time?

Depends on a lot of factors including climate, driving habits, and which battery you're talking about. There are two: the main battery and the support battery. I had both replaced in our 2017 XC90 after 3.5 years/68k miles, albeit preemptively. My battery on my last car went 2.5 years/70k miles and I was stranded on top of a mountain when it went dead. So my personal experience is around 3 years in a harsh climate and/or 70k miles.

AGM batteries are better than the typical flooded lead acid batteries. Expected life is 6 years, but it failed on my 2017 XC90 in just 2.5 years. Volvo replaced it under warranty.

To add to this, since I had the dealer replace them, they provided a 5 year unlimited miles warranty on both batteries. And they price matched the online prices (almost $200 less).

We we sold our XC70 after 13 years, the original battery was still in good shape.
This may be exceptional, but it shows, as you wrote, that it depends on a lot of factors

Volvo uses a pretty good battery. I'm always surprised how rare it is that I need to jump start a car. Generally it's just if they are in the showroom too long. Other brands we kept a jump box by the front door. Here I haven't used it perhaps at all this year.
My 16 XC90 since 1/16, both batteries and stop/start are working perfect, although I disable this function 95% of the time. I think battery health check is part of the annual/ every 10K services(multi-point check list?) if your car is serviced at the dealer. You can also go to an auto store like Advanced Auto Parts ask to check the battery for free.

AGM batteries are pretty durable. My Audi is now 8 years old and still has its original battery running strong
