My Radio Shack wanted $20 for a new 4.5 volt for my Performa 636 so instead
I just bought 3 N cells (the half-tall AA size) and soldered them together
in series (with wires so they'd fold over into a neat little triangular
pyramid) and to the connector and velcroed it back in place Been working
like a charm ever since. 4.5 V is 4.5 V, plus it should last a lot longer
than the $20 one would have.

Hmmmm. I always thought that an electric appliance was designed for 4.5 V
(for example) AND a particular current. That is why I thought I could not
connect a car battery on a 12V handheld flashlight.
