A penny battery knocks out the PlayStation 4. Consoles bought 4 years ago and later are at risk

About three weeks ago, we wrote about the so-called “time bomb” in PlayStation 4: it turned out that the CMOS battery affects the performance of the console much more than in a regular PC. Now the importance of this element is confirmed by enthusiasts: indeed, if the battery is removed or it runs out over time, there will be trouble.

This trouble is expressed in the inability to play either offline (from physical media) or digital versions of games – in any case, you will need to connect to PSN. Installation files of various games can also be damaged, which is also very unpleasant.

If you want proof of the #cmos issue with ps4's then heres video. I took out the battery and put the ps4 back together. The result, no physical or digital games work offline without connecting to Sony's server. ALSO may cause game install data corruption @dark1x @Dachsjaeger pt1 pic.twitter.com/ltCmh6M6rH

The problem is that the battery life is about 3-5 years, while the PlayStation 4 has been in production for 8 years. Therefore, anyone who bought a console 4 years ago or later could potentially encounter the CE-30391-6 error, which indicates a problem with the CMOS battery. And there is only one solution – replacing the battery with a new one.
