I think PowerGenix consumer products have been discontinued for a few years, so this is probably old stock. This is probably a dead end, and completely unnecessary anyway since LSD NiMH’s can hold a charge and undergo a lot more cycles.
Don’t know about the Turnigy cells. Maybe there is some demand for replacement NiZn cells?
The only advantage to NiZn is the higher nominal voltage of about 1.6v vs 1.2v of Ni-mh. For example I’ve used NiZn cells in a Xeno E03, and it provided a nice increase in output over regular eneloops.
I picked up a charger and 4x NiZn cells at biglotts a while back for only $6.
OK, I agree. But the batteries are too delicate. I have read that if you discharge below a certain voltage (much higher thant the 0,9volt of the nimh) the batteries die instantly, not as the NiMh or Li-ion, that you can use them… but the batteries will not be at 100% health
It seems far more likely that it was just a case of the charger refusing to charge the battery because the voltage was too low. This can even happen with NiMH, and it doesn’t automatically mean that the cell is completely dead.
I’m not saying that you can’t kill a NiZn cell by over-discharging it (or any other type of cell for that matter), only that you’d typically have to do a lot more than discharge it below 1 volt or so just once.
No, I can verify that they are easily killed. A couple of them I don’t think I even discharged too much, but they simply stopped working. I had 12 of them and every time my SC51 accidentally came on and discharged them, the cell was dead. I have a few left but no longer use them. A shame since they really kick out the current when new.
