They work as designed
There’s a few devices that use multiple AA alkaline cells that I chose to power with lithium ion 14500 3.7v cells and these blank(dummy) units are perfect to adjust the voltage. They are simple and straightforward pass through vehicles. I recommend this product.

Won’t hold a charge
Tried for days to get these to charge. They did not. The description is accurate. One star off for my frustrations. Good product.
