Our Histo Lab uses "charged" slides for IHC and I use them for frozen
section  immunofluorescence.  I can't comment on the longevity of the
charge because we use them up so fast.  But I have had a problem with
a crosshatch pattern background due to poor QC when they paint the
label on.  We used to use slides from Fisher, but Surgipath gave us a
better price per case.
