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?
I've used those 4.8V rechargeable battery packs for cordless phones as the emergency
retract batteries in a few RK05 drives, and they seem to work just fine. Just make
sure you get a NiCd pack rather than NiMH as there are charging differences and I'm
not sure if NiMH batteries would be happy in the charging circuit of an RK05 (but, who
knows, they may work, I just haven't tried it).
