One trick that often works is to zap the 9.6 v battery with a 12 volt
car battery for 5-10 seconds. The sudden rush of current will melt the
crystal dendrills that form thru the electrolite and discharge some
cells. After the zap, if you have full voltage on the battery (check
with a voltmeter!) then the battery will charge normally on the charger
and work in use. The fix won't last forever, you'll probably have to
zap it every time you want to charge it because the crystals punched a
hole in the separator that will allow the crystals to regrow. If your
use is infrequent you can live with it for years.
