Anyone have a line on batteries for the NLS portable oscilloscope?

Those are *very* standardized, in terms of similar sizes being offered by a great many different manufacturers. When I was doing the retail battery thing some years back (roughly 1993-5), we carried PowerSonic and one other brand I'm not remembering at the moment, and the sizes for similar capacities was a pretty good match for the Panasonic units listed in the Digi-Key catalog. Folks would come in with all sorts of other units and I was usually able to match them up with something that would fit. I've never seen single cells, but we did have some 4V units which were only two cells. Capacity in any given size of box seems to gradually increase over time. I've seen 6, 6.5, and 7AH in exactly the same size container, for example. Shipping is going to be the worst of it. I'd find some national chain convenient to you (Batteries Plus being an example) and then see if you can get them to order what you need, and it won't cost you for shipping at all. Feel free to direct any other battery-related questions my way, if you have any. :-) -- Member of the toughest, meanest, deadliest, most unrelenting -- and ablest -- form of life in this section of space, a critter that can be killed but can't be tamed. --Robert A.
