So My Phat PS2 has begun the "Turn it on and set the clock every time." loop. Which I assume means I need to swap out the internal battery with a new one.

Is it as simple as opening it up and taking the battery out or do I have to take the whole thing apart and desolder /solder something?

Look it up on YouTube didn't yield many satisfactory results.

Depends on the model, some have it on the side of the disc drive which is accessible after lifting off the top shell. Be careful as you can very easily accidentally disconnect the power button ribbon cable from the main board if you haven't done this before. If it's not located here, it is on the main board which will require complete disassembly. They are socketed as well.

Soldering is only needed on early SCPH-3000x (V1/2) units, the position of the battery socket there is pure evil, you need to desolder the daughter board from the motherboard assembly,Late 10 screw models and all 8 screw models have the battery in a more sane location, most will still require extensive disassembly
V4 is the easiest, has the battery on the side of the dvd drive V5-11 need to be fully disassembled. V3 is the same as V1/2 but the assembly is stacked rather than soldered, one of the easiest to do

Once youve taken it apart all you have to do is pop out the battery and replace it set the time and there you go, had to do this a while back as mine finally died
