Hello all!

I am looking for a replacement battery for a Tektronix "Power Scout"
222PS portable scope. The original battery supplied by Tek consists
of two Panasonic 4 V 2.2 Ah/20h gel cell batteries glued together and
wired in series. The Tek label rates this combination at 8.0 V,
2.1 Ah/10h and gives the part number as 146-0075-00. (This same battery
may have been used in the other portable scopes like this one, like maybe
the 222/A and 224.)

The Panasonic part number for each battery is LC-2042R1PU . I can't
find this number, but they are the same size, shape, and terminal
configuration as the (discontinued) LCS-214P,
http://www.panasonic.com/industrial/...scontinued.pdf
.. (Tek welded some tabs onto the battery terminals to connect the wires
to.) I have checked some of the usual suspects (Power Sonic, CSB,
Yuasa/Enersys, and Sonnenschein) and none of them make exactly this
battery. Power Sonic makes some 4 V batteries that are physically and
electrically too big. They also make an 8 V 3.2 Ah battery
http://www.power-sonic.com/ps-832.pdf that will almost fit in
the hole except it's just a bit too long (the 5.3"/134 mm dimension).

If I can't find the right battery, I have other options. I sort of want
to stay with lead-acid or with something that has a compatible charging
requirement so I can keep using the charger built into the scope. If I
can find a 12 V battery that fits in the hole, I can run it into the
external power jack on the scope, but then I have to come up with a
separate charger for the battery. Or, maybe I can stack up some NiCd,
NiMH, or 2 V SLA cells to get there.

Any tips or leads will be appreciated. Thanks!
