The battery will most likely drain over time and not store any of the information, and will need to be replaced with a new one. It stores it for a good amount of time whenever the system is unplugged so that the owner of the system will not have to reapply any settings after the system not having power for a few minutes, hours, or even days or weeks.

This is because there is a clock battery inside the PS2 that stores the system's information, like date and time and a few other system configuration settings. In some cases, just after unplugging or turning off the system, turning it back on can cause the system to lose its time again, making the orbs static in one circle and the system going back to the same date with the time going up. Whichever way you need to go, check out the fan repair guide. The fan is connected with just one small plug inside the unit, so before resulting to a complete replacement, try taking apart your PS2 to check the connection. The system can lose track of time after a long period of being disconnected, and you will need to set the date from to the current date. If you look on the back of the PS2 and the fan isn't spinning, it may be time to replace the fan.

They spin in motion with the system's time, and if the system is stuck with the time not going up or down, the orbs will stay static. Load any game (with PADEMU and VMC enabled to mimic my setup).

To Reproduce Steps to reproduce the behavior: Use the same USB drive (or something equivalent to it I guess) to load games. The blue spinning orbs or dots that you see on the menu that gives you the option to go to the Browser or System Configuration are connected to the system clock.
