It had one of the 3.6v batteries like most older Macs but with wire leads (sort of like the old paper wound capacitors). Since I was a bit leery of soldering directly on the mother board, I clipped the battery leads close to the battery. Next I clipped the wire leads from an old capacitor and "tack soldered" them to each end of a 3.6v PRAM battery, using low temp solder. I then soldered these new leads to the wire protruding from the mother board, using alligator clips as heat sinks between the new battery and the mother board. Back in business.
