Re: HP82161A Battery Voltage Message #3 Posted by Steve on 30 Mar 1999, 7:01 p.m., in response to message #2 by DaveC
Yeah, internal resistance all right. :-(
The batteries are not too fresh, having a combined output of 6.05 volts under no load (I would expect 6.4 to 6.8 for new cells (1.6 to 1.7v per cell))
Under load the analogue multimeter shows a drop to around 4 volts from time to time as the cassette motor does it's thing.
Maybe I'll try to find some nicads or maybe NiMH batteries that I can put together in a pack and squeeze into the battery compartment.
But the originals (nicads I assume) were 4 cells (4.8v) or 5 cells (6v)????
