If that is the siren module it gets constant +12v from the battery provided Fuses 11A/2 and F16 are good so it should be charged after a few hours and definitely over night regardless of ignition state. Silly question but worth asking, are you sure you connected the battery leads correctly?

Also, it looks like there is corrosion on some pins on the IC, in the red circle. Hard to see for sure but I've been in a similar situation with a door controller.

Ouch, yeah its dosnt look good. Didnt notice that when I had it out, thought it looked good in general so I didnt eyeballed it to long.

No codes that I'm aware of and its newly serviced at Volvo with all green system and even "newlyer" at Volvo for some other work where they noticed the message in the display but couldnt find any codes.

 

Do you have any alarm codes, they may need to be erased.
Below is a big list of codes that the car monitors for. I posted them to show what is wrote into the logic and possible problems that all car not just Volvo monitors. The Engine, transmission, brakes, suspension, audio, SRS, climate control are not listed here. I did not see any specific alarm codes. A battery reset may help. Remove both battery cables and touch the cables together for 10 seconds or so. Or use a jumper wire. This will erase any stored memory in the ROM/RAM.

I too replaced the battery pack in one of those alarms. Charged it beforehand, it didn't work. The metal box the alarm unit sits in looked quite corroded, it "lives" in a position high up in the front wheelarch, where it is exposed to water.

Someone on the UK Volvo owners site indicated they had had success by replacing the unit with a second hand one from a 2014 Mazda 2 . I bought one, I think it was £14 delivered, fitted it, still "alarm service message", but overnight it disappeared, presumably as it's battery got charged.

The Mazda one clearly was fitted where water exposure was not an issue. No external corrosion on it at all. I'll post the part number later.

 

The part number on the siren I bought, not on the bracket, was 6G9N-19G229-CG ( original on my Polestar was 6G9N-19G229-BK
