17 Feb 2023 - Version 2 has the
female 9V snaps turned 45 degrees because the vendor changed the
product and no longer offers the earlier version.
5 June 2014 - New lower cost version
This one does not have provision for the large battery snaps, it
just has small snaps for five 9V batteries. This opens up
room down the center for a buss that can be wired to either end so
that you can chain a number of sticks to make 90 or higher voltage
battery packs. This also allows the printed circuit board to
be the same size as the batteries allowing tight packing.
There are 4 mounting holes that will clear a No. 4 screw.
These are now for sale. See my
products
for sale web page.
Eveready No. 455 - NEDA 201
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.
There are narrow spots on the traces to each of the big snaps so
that the snaps can be electrically isolated from the local
batteries. At the left and right side in the photo below
there are jumper positions to allow a series connection of the
sticks to make 90, 180, etc. voltage battery packs.
Technical problem with large snaps prevents
this becoming a product.
