I've done that -- clip several in series. Not sure I'd want
a higher DC voltage. But, who knows?

What's a way to use up old 9 volt transistor batteries?
I've
got a couple dozen that still have some charge. I figure
with a couple battery clips, I could put two in series.
Dump
the charge into 12 volt lead acid batteries to keep my
devices going some day when the power is out.

One of the charge bases for my FRS walkies takes 9 volts
in.
Maybe rig something up, and parallel a couple transistor
batteries to keep FRS walkie charged.

If you want to run things, you make an external pack to
run the
device drect. Probably several 9V batteries in parallel
to get the
needed current.

Or several in series to get more voltage, and then parallel
the
series groups to get more current at that higher voltage.
Note that to
connect them in series, you don't *need* and clip leads or
other
connectors -- you just snap the button of one into the cage
of the
other, and keep doing that until you have enough in series.
That is one
of the nice things about those battery connectors, though I
would use
new batteries for anything which matters, as the output
voltage of the
old cells will be a function of how discharged they are when
you start.

Enjoy,

Someday I will get bored enough to take two new alkaline 9V batteries
and snap them together.
