Brooke -
Thanks for the suggestion. I did want to replace them with the same
chemistry for the reasons you stated. You are of course also correct that
the more modern cells have a higher A/Hr capacity. So, sounds like regular
modern NiCd D cells will be the way to go. That was my inclination to begin
with, but, since John was probably also facing a similar problem I thought I
would ask. Thanks for the ideas and the URL. I will check them out. 73 -

Hi Mike:
http://www.batteryspace.com has a number of Ni-Cad and Ni-MH cells.
It's a good idea to replace with the same chemistry so that the charger
works properly. Most modern batteries have a capacity that's much
higher than batteries 10 or 20 years ago, so getting the exact same size
is not so important. Better to make up a smaller battery but that has
about the same number of cells and Amp-Hour capacity. Note that many
cells are available with pre welded tabs to simplify making up a battery
pack. They also have a number of pre assembled battery packs, one of
which may be just what you need.
I see that John already has posted that the battery was 12 F cells
each speced as 1.2 Volts and 7 AH. This is less than a modern D cell.
Battery Space also carries Universal chargers that are the Burp type
which are in my opinion the only way to go.
http://www.batteryspace.com/index.asp?PageAction=VIEWCATSCategory=944
- some 12 and 14.4 Volt packs.
But if a 2x6 configuration is not correct then combine some smaller
packs like:

If you make an online order use the discount code:batteryspace
for a little off.
Have Fun,

BTW, John, I meant to ask you this before when you mentioned this clock,
but
what did you decide to do about the backup batteries, if anything? I have
not found a source for those 1.5 size NiCd D cells that were in there. The
clock of course works fine without them, but, it would be nice to get it
back to original. I may just have to go with external backup batteries. -

Not HP, but it seems that manuals for Austron gear are always hard to
find. At the moment, I'd like to find one for the 1210D portable clock.

Thanks John, I wonder if the group has any requests.
I'm working on a personal project to scan a considerable archive of
documentation. It has required me to write a lot of custom OCR software
and I
thought I would try it on my favorite source first.
What's the most requested or desired manual or manuals?
Jack
