Hi;
I'd suggest briefly shorting the batteries' terminals with the batteries installed, as stated in all Voyagers manuals. The brief short circuit must be fast enough to ensure the voltage in their terminals briefly drops to zero AND THAT the batteries' energy is not drain too much. Of course, even the briefest short will be equivalent to some hours of calculator activity.
The reason to keep the batteries in place has already been discussed in this forum some time ago, and I still believe that the batteries make sure the voltage in their terminals never goes higher than 4.5Vcc, so there is no way to dammage the calculator with an ESD if they are in place. If you remove the bateries and short the calculator terminals without them, chances are that residiual static electricity is trasnfered to the calculator circuitry and it may hang. It may happen.
I prefer loosing a few hours of calculator activity...
My 2¢.
