Hmm I happen to own a very old 4 bay AA charger that charges AA batteries as High as they want to go [ No voltage cut off ] , I think its strictly resistance regulated , because it does stop charging when a battery is full . So once internal battery resistance builds up [ battery is full ] the charger stops .
Dont ask me where to get one , as this was gifted to me , and its at least a decade old .
Nimh charger should be fine , but if you cant get the voltage up , the batteries will hold very little charge making them next to useless .
Discharge is with Powerex , not sure if powerex will take them as high [ Voltage ] as they need to go .
NIZN 's call to fame is its higher voltage , higher voltage usually means [ flashlights ] higher performance or brighter lights ..
Its also a safer chemistry than say Li-ion , so for those who demand the opportunity to Turbo a light [ Stuff in a Li-ion for higher performance ] , the NIZN offers a safer alternative , [ Safer for the user and the light itself ]
Fully Discharged , under load I have been discharging mine all the way to 0.9v , this is the normal for AA . At rest the voltage bounces back to 1.6v and then some .. So resting voltage and a discharged state is around 1.6? volts .. And a fully charged resting voltage is 1.8? volts [ Mine seem to be 1.84v ] So resting voltage wise its a some what small variation between empty and full .. Under load the variable is the amount of charge the battery holds . They are what they are [ battery wise ] , and I still prefer a decent LSD Nimh myself , especially in multi battery lights , but those single AA lights , well , Ive been using a NIZN in my Balder HD-1 ..
Long term ? If you buy a few to compliment your AA collection , my Powergenix are a Year + a little bit old ? I think . [ Checked = 1 year old ] and have lost no capacity ..
How long they will last ? - I think they were some what of a flash in the pan , people took a keen interest , and then the interest faded . So there is not nearly the amount of info out there as for LSD nimh , because only a very small % shares information ..
I see there are several flavors online now. I noticed on ebay that there were "generic blue and green label" as well as "old version & new version" Powergenix. I did not see Turnigy, but found them in a hobby shop website.
Any feeling or knowledge of who is really making these? Are all of them from the same Mfg? Just curious, as I remember that the first Powergenix were hit and miss and didn't hold up long term. I don't know about the newer generations of them.
From my standpoint, since I do so many 2AA lights, they are interesting, but still not as interesting as just supplying a dummy cell and letting people use their Li-ions. It's more for my personal use.
I thought this technology had died a natural death! It never really got started, as far as I could tell, and with that rate of self-discharge, I’m not surprised.
Here in our place we have been using these batteries to run our m4wd toys. a combination of one eneloop 1900 and Powegenix or Turnigy Nizn batteries.
So far doing great. We use chargers provided by Power Genix and Unicell. The unicell chargers are better because batteries are individually charged. But we don’t
discount the Power Genix batteries specially if you’re in a hurry to charge batteries or you need to boost the batteries.
The key for these batteries to last long is never fully discharge them. We automatically charge them again and boost the batteries before the race. so far no problem.
No memory effect too not like in NICAD batteries. My friend advised me to use another brand BPI and said that it is better than the two. Let’s see.
