It's just silicone caulking, just rip it off. I would also dust the board with a chip brush (non-plastic).
Usually it goes 10mA per month roughly. The original battery I think is 50-60mAh, coin cells are actually higher in capacity than the originals. A VG2430 is about 90mAh. You just need to make sure the battery is fully charged if you plan to leave it in storage for a bit.
does the board you posted pics of work ok? The corrosion doesn't look all that bad to me. Just clean it up/neutralize the leakage and you should be fine.
As for the board you purchased recently: What's it look like, how bad is the corrosion?
I finally decided to pull out my battery in my 2 slot, as well as from my PGM mobo. I’ve yet to add the coin cell to the 2slot (hopefully soon), but that seems easy and straightforward (even with my very low soldering skills).
The PGM tho, I managed to install the coin cell battery holder (no battery in for the moment), and remove the D2 diode. But the 470ohm resistor marked R24 on the back of the mobo, I’m not really sure how to remove it. Am I supposed to desolder on both sides of the little 471, and try to pull it out? It seems mighty small.
