Hi textory,
After you have carefully removed the battery, I recommend that you do NOT replace it. The Amiga 2000 computer does not need a battery. The files really do not care about what day or time it is. If YOU need the correct day or time, you can always enter it in manually at startup. Then as long as your Amiga 2000 is on it will keep the correct date and time. I have four (4) Amiga 2000 Series computers and have removed the batteries from all of them. They are much happier now. :-D
