How can I recover a bum battery?

That fixed the second battery - when I plugged in the AC power to the
XO, the Battery LED first turned yellow, and after a period of charging
turned green.  I'm concluding the second battery is o.k.  Thanks.

On the first battery, the values did change - but the Battery LED on the
XO still stays dark when the AC power is plugged in.  [By the way, I
have an XO-1.5 B2, if running batman.fth there would help things.]
