(Replaced by 50-0059-003)
50-0059-003 12v DC
50-0059-003 LIEN 3.6 AMP
Works with the X-C 6000 and 6250.
The split pin design was chosen for more positive connection
Center positive. 12vDC
Thanks to Andrew C. Blakely for getting me to finally pop one open...
I bought an extra pack off ebay, knowing that it was only
1900mAH, and probably in bad shape. I tried charging it, but it started to
leak acid, leaving white crystal deposits on the outside of the pack. Prime
candidate for disassembly... I used a pair of Channel Locks to crack the seams,
then a knife to (slowly!) pry the halves of the pack open.
B Ground lead
C1 SMD capacitor
R Positive lead (to cells 4 & 5)
R1 SMD resistor, 301
R2 SMD resistor, 121
TVS1 Uh...MOSFET??? M12

Between Cells 4 and 5
Please note that all other tabs are attached dead center,
while the tab between #4 and #5 is offset and sticks out so the red lead
can be attached to it. Length of the tab to include extension for red lead
is 1.38" (@ 36mm), amount bent over battery is .33" (@ 9mm).
Battery Pack Components for 1900mAH Battery
Dallas DS2434. DS2434 Data Sheet
VSE 4/3 A
1.2V - 1.9A charge 190mA x 16 hours
I guess that a 4500mAH pack would take 6 1.2v 4500mAH
batteries. Please make sure you use the AC Adapter 50-0059-002 or 50-0059-003
to charge the 4500mAH pack. These AC adapters can handle 3.6A
Batteries for Replacement
The Battery Station,in
Ottumwa, Iowa has Nicad
and Metal Hydride Batteries
HR-4/3FAUX Sanyo 4/3A 18x67mm, NiMH Flat Top 4500mah $5.50 (Actual cell width
on 1900mAH batteries is 17mm, BUT Andy Blakely used the 18mm diameter cells
and it fits).
For packs up to 10 cells, just add $5 to the total cell cost per pack. Style
24 (two sticks with 3 cells). Still working on the easiest way to order these-
you'll see what I mean, read below...

I have some good news. I got my assembled batteries from
BatteryStation.com. And when I say assembled, I mean ASSEMBLED.
They not only put the cells together, but also shrink-wrapped both rows of
cells in white plastic, glued them together with a bead of hot glue, and
then wrapped the whole pack in black shrink-wrapping. I'll show you
some pictures after
I pull them off my camera. After the agonizing process of stripping
all the shrink-wrapping off, I realized that these Sanyos are the same green
with black letters "Japan 4500mah" as my originals! I carefully took
the do-dads off the original cell and connected them to my new pack.
I didn't have any soldering tools or other ideal ways to connect the wires,
so I just used electrical tape on the red wire, and crimped the tabs together
tightly with needle-nose pliers. I hated doing it this way, but the
connections worked and I was too excited to wait and borrow tools.
Plugging the new battery pack into my xc6250 was the
scariest part - by FAR! Without external power, I connected it and immediately
all the lights flashed on & off (and everywhere in between), and a whining
sound escaped through the pc speaker! (Ed.
I think this could be a low battery alarm) Of course, I ripped the pack back
out in fear that I just destroyed the computer! Tried again, and the
same thing happened. Plugged external power in, booted into Win95 just fine,
opened Battery Maintenance, and hesitantly plugged the thing in (expecting
an explosion or house-fire).... BOOM! It worked. *smile*
It even detected the battery's serial number, temperature, gas guage at 0%,
the rating of 4500mah, EVERYTHING worked. So I started a deep cycle

Computer Battery Memory and Charge Parameter Messages.
"the DS2434, features an ID code that the user can define so his supporting
electronics can identify that battery pack as one of his. The DS2434 removes
the requirement for a thermistor in the battery pack because it features
a direct-to-digital thermometer to allow for self-discharge calculations
based on the environment to which the battery has been subjected. The final
core feature of the DS2434 is on-chip non-volatile memory to allow the designer
to carry around vital
data such as gas gauge levels, warranty information, lot codes, etc. in the
Known Problems in XC95TOOL Version 308
Do not run the Battery Maintenance application on units that
have 80C552 firmware version 0.04 or less. Doing so will cause the battery
pack to have decreasing capacity.
