There is a need to replace 45, 90, 180,
etc. Volt dry batteries using common 9 Volt batteries and an
adapter. This is my first attempt at a 45 Volt stick. It
has been designed to allow connection of multiple sticks in series to
get the higher voltages. It also has large snaps on the top to
emulate the 455 45 Volt battery electrically, but it is not physically
the same size as the 455 battery.
