sounds like the battery acid leaked out and started eating away. Only way
to know if damage has been done is to see if the board still works (boots)
or not. You can't really clean it off without doing some damage to the
traces.

The tabe are usually spot welded on. Most cells are designed to go into
some sort of holder that has contacts. You might have to rig up a battery
with pigtail leads and attach that to the mobo, with the battery stuck on
somewhere with RTV or other adhesive.
