I shave off
the top of the DS1287s and replace the cell. It's easy
to find the battery on those as it's magnetic!
Interesting! What tooling do you use to do this?
I file down
the half of the molded top where the battery is until I
reach the + pole of the battery. I use the wire of the + pole as a guide
for the next step. I use some Dremel like tool to mill the side of the
molded top away until I can access the + and - pole / the wires coming
out of the chip. Then I disconnect only the + wire from the battery,
solder wires to the wires coming out of the lower part of the chip and
attach a new battery. Finaly I put some glue on the miled side of the
chip to support the new wires.
