Hi, All,
The topic of replacement batteries came up in the Yahoo Group
for the RB5X, and someone posted a link for 2 volt 2.5 Amp-hour
cells (which are apparently used in an older version of the robot
than mine)...
<http://www.batteryweb.com/hawkersla-detail.cfm?Model=0810-0004&label=singlecell>
I saw the image and immediately thought of my NLS portable oscilloscope.
I'd love to refurb mine, but $45 in batteries is a little on the high
side for me.
Has anyone on the list replaced a set of this sort of battery, and does anyone
know of a place that stocks them for a bit less?

Are we talking about more or less standard gel cells? The 2V terminal voltage
would seem to indicate so.
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. :-)

I'm not concerned about specific vendors - just D-sized (to fit the
enclosure) with solder-tabs.
I've never seen single cells, but we did have
some 4V units which were only
two cells.
My NLS has 3 single cells, bonded together, IIRC. I would be happy to
solder up loose 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.
Capactity isn't really a show-stopper for the oscilloscope, but I
think I do need good batteries in there to function, even when plugged
in.

I can certainly start there. There's one nearby, and I have a target
price of $7 each (ex. S&H)

On re-reading my earlier post, I *do* remember D-sized single cells, with
tabs on them. I think spade lugs were perhaps the more usual means of
connecting to them but I don't see soldering as being that much of a problem
either. Gates made 'em.
There were also sets of 2, 3, and 6 cells packaged in plastic and in various
sizes including D sized. Some lawn mowers used these for starting! In some
cases we were able to get a replacement pack that included a six-cell setup
that would go inside the original plastic box.
I didn't know that about those little scopes, which I'd still like to get one
of someday, just to play with it. :-) I remember them coming out with a
dual-trace model too, and can't quite imagine how that'd be on that small of
a screen.
There you go, then.

But, it was often there when no other scope would have been.

Yup! I have a 5xx series Tek, huge and clunky, and also a 2246, which is a
bit more portable, even the accessory pouch to carry the probes and such and
the protective cover to go over the front of it, but I sure wouldn't want
that living in the trunk of my car, and all that entails.
Those little bitty ones, though, look like they'd fit in my toolbox. :-)
