NiZn rechargeable batteries - when Nickel and Zinc create a strong pair

1,6V rechargeable batteries experience “rebirth” and bring several advantages in comparison to 1,2V NiCd accumulators

Experts in electrotechnics might say, that these are a long-time known batteries invented already by Edison thus being no novelty at all. That´s true but in contrast to older tyes is in technological advance of electrolyte and electrodes so as to reach a substantially higher lifetime that few decades ago.

So what´s interesting about these rechargeable batteries? By one sentence, NiZn cell has an output voltage of approx. 1.65V, what´s about 0.4V more than NiMH/ NiCd cells.
At the same time they´re able to provide a high current, similarly like NiCd/ NiMH cells, that´s why they´re also usable in devices with high current demands (conductivity of Zinc is about 15% than Cd). NiZn cells are easily recyclable and they´re very environmentally friendly. Another benefits:

●energy density of NiZn cells is about a third higher than that of NiCd cells (Wh/kg and also Wh/liter).
●higher voltage (1,6-1,8V) enables to reach a higher voltage of „battery-packs“ with a lower count of cells
●lifetime is comparable with NiCd cells
●no memory effect, trouble-free recharge to 100%
●flat discharging characteristics, average voltage aprox. 1,6-1,7V

It is recommended to recharge NiZn cells by C/4 to 1C current (i.e. for example 500 mA to 2000 mA for a 2000mAh cell) while observing a max. voltage of 1.9V/ cell. It´s not recommended to leave cells at a so called “trickle charging” as overcharging might decrease lifetime of cells. Naturally, like in case of almost all rechargeable batteries, the highest lifetime can be reached at operation on a partial discharge (not to a deep discharge). It´s worth to say, that NiZn are not an ideal replacement into devices with a very small power consumption ( e-g- remote controllers), where still win primary alkaline cells.

In our offer can be found NiZn cells themselves: 4AA2500mWh1.6V BP4 and 4AAA900mWh1.6V BP4 as well as a set - charger + cells (4xAA+4xAAA) NizN Charger + Accu. This charger charges by 500 mA current (AA/AAA) and monitors each slot individually. During recharging a LED at agiven slot blinks slowly (1x/s) and after finishing of recharge it shines continuously. In case of a faulty cell it blinks quickly (4x/s).
