Maximum temperature raise at different discharge currents: 1A:+4,1°C, 2A:+8,0°C, 3A:+10,3°C, 5A:+9,3°C
An AAA version of a NiZn cell. Again the capacity is specified as mWh (A very optimistic value), not mAh, this makes the value look much better than any NiMH AAA cell, but it is not (Check the Wh for NiMH from some of my NiMH reviews).
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 cells are not a perfect match. They handles high current fairly well, but the capacity is significantly lower than NiMH.
The energy is lower than the specified 1.15Wh.
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.
I do not believe the cells are useable as replacent for alkaline or NiMH.
I have some of the NiZn battery`s in the review, they need a special charger as they charge to 1.8-1.9volts i would charge them slowly 0.5c as they can be easily damaged, I regret buying them really.
I used SkyRC MC3000 charger to charge my NiZn battery`s
My conclusion so far is that these batteries might have only one “ideal” use….
And that is in a VERY low discharge application where the device has an internal, built in discharge voltage cut off.
I have just such an application.
I have a number of Alarm remotes for various vehicles I own.
They are very low drain (0.5mA) and do have internally built in voltage cut off limits of 1.3v which will ensure the batteries are never critically drained.
If the battery has 400 mAh capacity from full charge to my cut off voltage of 1.3v and the drain is only .5mA I should get
I am still waiting to see the capacity of my NiZn cells, My SkyRC MC3000 has a setting for them, I just used the stock setting, But i set the capacity to 600mah and the charger picked an 300ma charge and an 150ma discharge rate, It appears to be charging to 1.9v but i can select 1.8v I don't know what the cut-off voltage is set too.
