Eveready #QCC4 battery recharger question

[tenplay]

I own an old Eveready #QCC4 battery recharger. The indicator lights
work with all batteries except for 9v's. On the lid, the directions say
to look at the manual for the case with 9v's. I cannot find the
directions and the Eveready website does not offer any for my recharger.
Thanks for any advice or suggestions. Mike

I once had a charger like this; while the AA/AAA cells were inserted
horizontally into wells, the 9V battery went standing on its top, plugged
into a connector sitting in between the AA/AAA wells. The indicator light
didn't work either. As I recall, the design was such that the 9V charging
circuit was pretty much an afterthought, and entirely separate from the
main circuit that charged the 1.2V cylindrical cells.
