DEC RK05 Emergency Retract Batteries

We started working on the RK05 drive that is part of the PDP-12 at the RICM.

The drve is very clean and in good condition. It will need new seals
between the blower and the card cage, and between the plenum and the disk
pack. I think that 1/2" and 1/4" weatherstrip from Home Depot will work

The NiCad batteries for emergency head retract are toast. These look like
standard 1.2V 2/3AA 400mAh cells. It looks like some cordless phones use
the same batteries so I can buy an assembled 4.8V battery pack.

Any other suggestions for replacement batteries for the RK05?
