I cannot solder it properly from the top side because of the corrosion. But it's soldered nicely from the bottom and has good continuity according to my multimeter. These leaking batteries are no joke and I am always very disheartened when I see such a corroded motherboard. Affects all board up to 486. Luckily, some newer 486 boards started using coin batteries.

I'll probably try to reflow all joints just to be sure and figure out how to strenghten the connections on the upper side. It's probably fine now but you can never be too sure. I'll put the board through more testing with external battery and see if works fine or not. Thanks for your advice!
