PS5 Slim may get more accessible CMOS battery
A teardown of one special edition points to a new motherboard, but Sony has not confirmed the change.
An independent technician has found a new motherboard in one special edition of the PlayStation 5 Slim. The CMOS battery therefore appears to be easier to reach, but there is still no evidence that this change is present in all models sold.
The finding comes from a teardown of the Wolverine Limited Edition of the PS5 Slim. The technician identified the motherboard as EDM-051 and also described changes to the cooling system and internal layout.
The built-in CR2032 battery helps maintain the console’s internal clock, among other functions. In older PS5 Slim models, the battery was reportedly harder to reach, according to the technical reporting consulted. In the example examined, replacement appears to be less involved for an experienced repairer.
The same teardown points to a different heatsink, modified protection around the liquid metal and a revised HDMI retimer. These are observations of the opened device, not measurements showing that the console operates more coolly, quietly or reliably.
Sony has not officially announced the change. It is also unclear which regular retail models, regions or production numbers use the EDM-051 board. Based on the available information, buyers therefore cannot know for certain which internal version is inside a box.
The report is mainly relevant to repair and longevity. A more accessible battery could make future maintenance easier, but no official repair procedure or warranty guidance has been published. Opening a console may also affect its warranty and safety.
For now, the correct conclusion is limited: one special PS5 Slim presumably contains a revised design. Until Sony provides information itself or several independent teardowns show the same thing, it remains unclear whether this is a broad product change or merely a limited production run.

The technical findings are limited to one dismantled console and are presented as such. Sony’s official information confirms the model, but not the new motherboard.

Editor's note
The available sources all refer to one teardown of a special edition and contain no confirmation from Sony. The status is therefore insufficient_sources, and performance claims have deliberately not been presented as facts.Sources
