I've been thinking about the same issue on an old T400s, which I
keep for the rare occasions needing a Windows system.

The charging voltage limits for the higher-performance lithium 
chemistries are relatively narrow and likely depend somewhat on
manufacturing details that could easily drift over decades. It
might be worth looking up the original cell specs now, on the 
supposition that the charge management is matched to it. 

Measuring the old set under charge might be informative also,
unless it's totally dead.

Presumably one should err on the side of undercharge, not over....

Thanks for reading,
