Battle of the NIZN - Turnigy VS PowerGenix

Battle of the NIZN 


Turnigy VS PowerGenix  By old4570


Photobucket



BatteryCapacity
PowerGenix1349mAh @ 500mAh Discharge
Turnigy1531mAh @ 500mAh Discharge


Wow , this was a interesting test , the first time around the Turnigy returned some 906mAh  , and the second time it returned some 1531mAh . Now I find this interesting enough for a round 2 . I will charge both batteries the exact same time and hopefully voltage level , and then discharge again . A quick note , NIZN in my charger reach about 1.94v and after some time to rest settle at about 1.84v .  Im happy to see the Turnigy reach claimed capacity [ 1500mah ] rather than fall short . I really want to see if there is another increase in capacity in the Turnigy , so stay tunned for part 2 .

The resulting sound may , or may not be worth listening too ….

Nice! Thanks for the tests.

What charger are you using to charge and discharge the cells?

Love the high voltage chemistry but not so sure with what charger to get.

Can I use the same delta peak charging method for NiMH’s?

Merry Christmas.

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 .

Gotcha, thanks for your reply.

Looking forward to the second round. Big Smile

Hmm…. just did a quick search and NiZn’s terminal voltage should be 1.9V, just like li-ions have a max voltage of 4.2V.

Screw capacity, see if the Turnigy are more robust. Maybe overdischarge both to see if the Turnigy can handle more (i.e. any) abuse.

No but really, thanks for the tests. Smile

Both are being discharged to 0.9v under load ...   

I also have another PowerGenix , doing nothing for maybe a year ?????  Has not seen a charger in that time anyways ...  Sitting on 1.67v   

I will discharge it to see what capacity it has ...

Wow! Interesting test!

Do you do any discharge testing. I mean, X amps for X amount of time. All I would care about is how they handle discharge under heavy loads, 3 amps+

I don't know if you have the stuff to do that, or the interest.

Wow 3A +   , My hobby charger could do that [ Discharge ] , But no time - Going prospecting !  

NIZN not being charged for 12 months = 227mAh capacity [ or longer than 12 months ]  @ 1.67v  [ LSD I dont think so ]  

After Being discharged to 0.9v the voltage does bounce back to around 1.6v , so 1.6?v = almost no charge left ..

Ive found all Turnigy LSD nimh and Nizn to be underrated in capacity Also hold their charge like eneloops.

Definitely a bargain if choosing cheap shipping .

Thanks for the test.

Does NiZn really is a chemistry worth to invest in?

How many cycles do they last? Can be fully discharged with no worries?

Thanks!!!

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 tested a pair of PowerGenix in a 2xAA Nichia 219 Maglight… they really work well there.

Ok here we go .. I charged the batteries and then gave them a good 36 hour rest ... 

Turnigy returned 1472mAh 

PowerGenix returned 1282mAh  

So looks like there is some loss almost right away [ self discharge ]

So the Turnigy showed a 4% self discharge and the PG 5% during the 3 day period…. Interesting data!

Thanks for the tests!

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.

Cheers

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.

I wish I could find NiZn cells with overdischarge protection circuits built in.
And a trickle charger for them so I could leave them on the charger when not in use.
I gather that overdischarge is what kills them, and mine have never lasted very long.
Mostly from sitting on the shelf, I suspect, but I’ve never known what voltage level to watch for.
