SIMPLE FIX TO MAKE IT WORK
on February 12, 2014
I purchased this battery case, and like many reviewers pointed out... no electrical connection.
The reason it fails is because the battery case width (AAA's end to end) is a tiny fraction too small for the batteries when inserted. They tend to 'pop' out of their slots just a little bit, and thus no electrical circuit completed. Just closing the case top on them does not push them into the full seating required. This tends to be centralized on the 'middle' batteries of the group. I can only assume this is the general reason for the product not working... perhaps they designed the case based on a different battery manufacturer that has slightly short battery nibs... I don't know. (I always use Duracell alkaline batteries)
Insert your batteries inside the case shell, and take a small piece of 20-lb paper (common printer paper) which needs to be cut in a short rectangle with the edges just covering the footprint of the battery group installed. Place it over the batteries in such a manner that the paper edges do not interfere with the case back being installed. Slowly close the back up and you should be good to go.
The paper insert gives just enough fill to keep the batteries down allowing continued contact with the metal fingers of the case.
Battery pack now works.
