I have used these cards interchangeably for a number of years in an IIe.

The new battery is charging so it must be installed correctly. I have cleaned the card fingers.Any suggestions?My first question is how do you know the battery is charging?(There's no indicator.)I measured the voltage on the new battery prior to installing it in the IIe. After several hours I took the card out and re-measured the voltage which was higher that the original measurement.
OK.
Polarity is the only consideration in installation, aside from good contacts. Did anything happen to the card between the last time it worked and now?The battery on this card had failed so I removed it and stored the card (I really don't remember how long ago this was.) When I thought the battery was failing on my second card, I ordered two replacement batteries and installed one of this card. Although not an original replacement, it has the same specs as the replacement battery on the second card. I have replaced both batteries before.As far as I can tell, the switch settings, etc are the same on both cards
What *are* the specs on the replacement batteries? (They should be 3.6v and about 60-200mAh.) As I mentioned, the battery should be irrelevant when the card is installed and the computer is on. Can you set the clock under these conditions? (If the clock has not been set since it was powered off, it may not be running, which might be detected as "No Device connected" by the clock software.) -michael NadaNet networking for Apple II computers!
