In mine, the battery is a Tadiran AA 3.6 volt with
axial wire leads. Here is one source. This is also the same battery used in the
70900A/B and also other 70k modules so buy a few if you are into the 70k series
instruments.

WE have the schematics/CLIP for the 70004A but there is no
schematic for the A3 display section proper . This usually implies that the
display was originally a3rd party drop in and not a Agilent design
The
Service Guide refers to the battery being on the A5 board and elsewhere talks
about a red LED error light relating to a battery failure. But I did not see a
part number for the battery, there is a crude drawing showing the location on
page 4-10 in the service guide.

Thanks for the info on battery location, I went through the manual, and
did not find it, or any parts shown for it. it is not shown in the error
messages either, which is disturbing.
what possible purpose does this
battery serve, and why is there also one in the display? does anybody have a
part number for it, so I can get a replacement on order before I rip the
unit apart?
I am aware of the LCD replacement (I have one waiting to
install), but was just wondering if there's an internal intensity limit or
contrast I can tweak to get a bit more life out of this display before I go
that route. I don't see any schematics in these manuals so it's not as
helpful as it might be in that regard.
does anybody have a true
hardware level 70004A manual with schematics?
all the
best,
