Replacing the battery on an Apple IIGS

Which battery should you get for the Apple IIGS?

The real time clock chip takes 5V, so you can use either of the following replacement batteries:

The TL-5902 has more capacity, and has a lower discharge rate.



If you have a ROM 01 motherboard, you'll want to get the TL-5902/T which has solder tabs already attached.

If you have a ROM 3 motherboard, you'll wan tto get the TL-5902/S which is the normal button top.

Remember to check back in another twenty years!
