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=singl
ecell>
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 found THAT out the hard way.
When I sold my NLS215 at VCF, I had to sell it "AS-IS" because the
batteries wouldn't take a charge.

Assuming the battery pack is just a battery (that is, no 'battery
management' circuitry), you can often run the unit from a bench power
supply connected to the battery wires _with the battery disconnected_. Of
course this assuems you have a suitable PSU...

Gates was a major provider of the single 2V cell in the "D" size with tabs
on one end. 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 ones they make with multiple cells in a plastic case have a flat top
that's rectangular in cross-section and that might be an issue, depending on
the housing. A quick google gets me to this page:
http://www.batteryprice.com/0819-00126v25ahcyclonleadacidbattery.aspx
where there's a picture of one, what they're calling a "0819-0012 6v 2.5Ah
Cyclon Lead Acid Battery". Not a bad price at $15.70, either, if it'll
fit. The individual D sized cells are here:
http://www.batteryprice.com/0810-0004cyclonbattery.aspx
at $7.90 each, not terrific but not too terrible either.

Local store ( Ford Electronics, Southern CA ) has " D " size rechargeable
batteries with tabs spot welded on either end, 4.5 AmpHour for $10 .
Shipping might be a deal breaker... I've used the " C " and " AA "
sizes to
replace dead cells in battery packs by solder the new tabs to the old tabs
of the cells surgically removed.
Best regards, Steven

Yeah, I'd remembered that a bit later on...
My stint in the battery retail store biz went from January of 1993 to of 1995, so I'm a bit fuzzy about recalling some
of those details these
days. :-)

Are these lead-acid though? Or something else...
The different types are not at all interchangeable, at least as far as the
charger is concerned.

Roy,
Sorry for the delay, I saw something shiny and got distracted... They have
two " D " size batteries. The 4.5 AH is a NiCad ( 1.25 VDC ) with welded
tabs at either end. They also have a 2.5 AH Sealed Lead Acid Gel Cell ( 2
VDC ) with two tabs out the same end. I believe the first one is made by
Cyclon. The other sizes ( i.e. AA, etc. ) are NiCad and other non-lead-acid
families which I have used to replace dead cells in battery packs ( like for
my Milwaukee cordless drill ). Hope this helps.
Best regards, Steven
