Hi Guys
Just aquired a gridcase 1520, how do I remove the battery, and where might I find a
battery?

Can't tell you how to remove the battery, since I don't have a 1520.
As far as replacement, if you can't find it on E-bay, you'll need to
build a pack. I've found that for gridpads at least, your best bet is
to crack open the dead pack and replace the cells with NiMH's of the
same size (but, of course, greater capacity). Ten 2/3AA NiMH
batteries will set you back a whole $20.
The CMOS battery is tougher, since, IIRC, it's a 3.6V stack of NiCd
coins, which I've never even seen available separately. A 3.5V
lithium battery would probably do the job, but would cost $20 by
itself. Or you could build a stack of three 1.5V coins and risk
over-voltage.

Frank,
If you are talking about the main battery, it is in the back of the
computer. There is a push button mechanical release just under the
opening for the battery. When you push the button the battery should
pop out about 1/4 of an inch from the spring tension of the contacts.
If you are talking about the cmos battery, it is under the keyboard
bezel and it a little harder to get to. You have to disassemble the
computer, at least partially, to get to it.
The battery life on that series of the GRiDcase was so bad that most
people I knew who used them didn't bother to use them with batteries.
GRiD made an AC adapter that was the same size and shape as the battery
that fit into the battery slot and took a standard Euro-type power cord
to the wall.
The 1520 was based on the 80286 cpu and it wasn't really the most power
efficient. Couple that with a fairly power-hungry display on the
computer and you get about 15 minutes to 30 minutes of battery life on a
good pack.
Hope this helps.

If it's the same as the 1520 I had, IIRC there's a button below/next
to the battery (mine had a PSU instead of a battery). Press it, and
the battery/PSU will pop out about 1/4" and can then be withdrawn.
