10. Charging a Nickel Zinc Cell
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 benet 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). Specically
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.
