A4000 doesn't recognize AGA properly!

I attach the photos of the battery (leak).

That's a coin battery, they ususaly don't leak. Is your motherboard a 4000CR version? Or did someone replace the leaky type with this?

Any tip on chemical to neutralize the battery fluid with? (without frying the pcb..)

I used vinegar, then baking soda then isopropanol alcohol to clean everything off.

As previous owner of this Amiga told me this is a replacement battery of the old one. Do you see a leak on the photo? Because it seems that it's present.

I can't seem to blow the picture up big enough to be sure. I think I see some silicone sealant.
