No, mercury batteries are not rechargeable.
They are honestly a really major hazard, and need special disposal.

Subject: battery education sought
I noticed my HP 262X terminals have a "Duracell
TR133" battery in the back
to maintain settings when powered off. The battery indicates "Mercury" on
the side.
Are mercury batteries rechargable? I would have thought they'd use a nicad
or something to charge up while the unit was on.
The TR133 battery also indicates "4.2V". It seems the Duracell replacement
for this battery is Alkaline, and 4.5V. Should I use it?
