The battery here seems to be holding (3.7V) but as the datasheet shows the curve is pretty steep at the end, so difficult to know for sure its state. These are supposed to have a shelf life of 10 years, with a 34 yrs old oscilloscope and an unknown history this is pretty much a disaster waiting to happen.
