Reconditioning batteries for IBM Thinkpad X40?

I use an IBM Thinkpad X40 and need to recondition my batteries.

From Battery information, there was an option to recondition the battery.

These options seem to have dissapeared, right clicking the batter icon only brings up the "Close Battery Maximiser gauge"option.

Any ideas how I can access the option to recondition?
