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.)


Did you check to make sure your batteries are not just sulfated?
