Test/Review of NiZn AA 2800mWh (Green)
NiZn AA 2800mWh (Green)
Official specifications:
Maximum temperature raise at different discharge currents: 1A:+3,5°C, 2A:+5,4°C, 3A:+5,5°C, 5A:+1,8°C This rechargeable chemistry has higher voltage than NiMH and are supposed to be the superior replacement for alkaline in some applications. . In practical usage the cells has a rather low lifetime, probably because they are over discharged when used as replacement for alkaline or NiMH cells. The official capacity is not specified in mAh, but instead energy is specified in Wh, probably to hide the fact that they has less capacity than NiMH batteries. The two cells has different capacity, not very practical if they are supposed to replace a couple of alkalines and must not be fully discharged. The energy is significantly below the rated value. Conclusion The cells might be useful for some special applications, but as replacement for alkaline or NiMH they are not very good. The higher voltage might damage equipment and the cells will be damaged when discharged to much. The different in capacity between the two cell I have tested is not very good. I do not believe the cells are useable as replacent for alkaline or NiMH. Notes and links I have also tested PowerGenix AA NiZn cells. A better rechargeable replacement for alkaline might be Kentli How is the test done and how to read the charts Compare to other AA/AAA batteries: Alkaline/NiMH/Lithium
