NLS used three of them but a 6V monolythic battery with the same outer
dimensions will also work fine as the tabs soldered to the rear board for
mounting and to create a series connection.
The only reason batteries are needed to run the NLS is the charger is way
too small run run it directly.

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)...

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. :-)
