How long will the internal battery of my ps4 last?

I just read on the internet that the ps4 has an internal battery and when it is empty I can never play offline when I'm online. The most important (maybe?) First.

My Playstation is connected to the internet so I gugg youtube wrestling etc so nothing should happen to me right?

In the article stand that works until the support for the server and what has to do with the trophies.

You can then simply play offline without trophies. Put a lot of value on them anyway.

So now to my question above. I've had my Ps4 since about 2014-2015, I never know exactly and I play 2-3 hours almost every day, so how long does my internal battery last or can I check it somewhere and there's a warning beforehand according to the motto attention internal battery low.

And do I have to send it in to Sony or Mediamarkt or somewhere else or can I change the battery myself?

Thanks for the answers and hope you tell me the battery lasts an average of 25 years or so but I have no plan for it.

Oh, the said article is the following:

There's absolutely nothing to worry about. I've just heard about it for the first time, and after reading the article it becomes clear that this is more of a hypothetical and hardly practical problem.

I think it's like the PC with the BIOS. This always requires a low voltage to keep the settings. Otherwise you should please deduct it from the electricity.

Phew, then I'm relieved for now. As I said, I don't know anything about it and was shocked. Thanks for the quick answer and hope for the best now.

Stay healthy and I hope that there are no problems that I wrote the link in but seems to have helped here so with links ok for the future I hope
