Test setup: USB-cable, plug board, red LED, orange LED, resistor 100 Ω, battery 

holder, NiZn rechargeable battery AA mignon or AAA micro.
The nickel zinc cell (NiZn) is a very old and also more recent development on the 

rechargeable battery market. The benefit of this cell type is a higher cell voltage of 

approx. 1.6 V. Thus, it is better to replace disposable batteries (1.5 V). Specifically 

in electronic devices intended for only one or two battery cells, the NiMh-cells 

are frequently below the required operating voltage too quickly. This prevents the 

capacity from being used fully.
