GS Battery Replacement

[brian.hammack@rook.wa.com (Brian Hammack)]

The battery in my GS ROM 01 isn't dead yet but like us it will go one
day, so I'm trying to come up with a replacement.  I've read about the
slide-in replacements and all but I've decided that I want to keep the
same type of battery in my machine as was originally found there.

The battery in my ROM 01 is a Tadiran lithium TL-5101, 3.6V 850mAh,
size 1/2AA, with axial leads.  There are two possibilities here...

WITH LEADS:
Radio Shack     10046423 (RSU order)    $10.49
Jameco          33371                   $5.95

WITHOUT LEADS:
Radio Shack     23-026 (in-store)       $9.99
Jameco          126754                  $8.95

[Radio Shack:  1-800-THE-SHACK  ...  Jameco:  1-800-831-4242]

So I went in search of a PC-mount 1/2AA battery holder.  One can be
ordered from Radio Shack for $1.13 plus $1 shipping -- ask a RS sales
associate to order "RSU part 11354834" for you and it'll arrive in
your home (or wherever) in about a week.  Here's what I did with mine:

There are two tabs at the bottom; bend them "out" slightly and solder
an inch or so of wire to them as leads.  Desolder the axial leads on
the original battery carefully (hold the iron to the solder joint with
one hand and pull the battery with the other).  You will see markings
on the motherboard perfectly outlining where to put the battery holder;
put a small piece of double-stick foam tape about the size of the
bottom of the holder in the outline, leaving the backing (if any) on
the side which faces up.  Cut a second piece of double-stick foam tape
for the bottom of the battery holder and again leave the outer surface
covered.  Now a moment of soldering to join the ends of the wires to
the vacated joints -- negative toward the front of the CPU, positive
toward the back (the holder I got has the poles marked clearly) --
and once in you can pull the backing off the pieces of tape and stick
the holder in square.  I used two pieces of foam tape to elevate the
battery holder's contacts above the PC board because there are some
solder joints near the PC's positive contact I wanted to avoid.

When done right it'll look like Apple intended battery replacement to
be a fast and easy procedure, and you can use Macintosh batteries as
a testiment that Apple got the clue eventually.  :)
