NI-Zn AAA / AA and sub-c

found a seller on the bay selling all different Ni-Zn batteries including sub-Cs http://stores.ebay.co.uk/Recycle-Powers-Store/_i.html

2

i have orderd 8 AAAs

we will see what they are like when i get them

3

I look forward to your review. Its strange that some of the batts the seller has seem like unbranded NI-Zn.

4

Ultracell ?

5

i have notification the order has been shipped

i will let you know if they are any good once i get them

i have a couple of 2xAAA light that are not all that good on Ni-mh but really good on energizer lithium's

at the price i thought they were worth the gamble

6

Yeah thats what I'm thinking that if they are any good it would be great for my DQG instead of buying Energizer lithiums.

Wow, good find! Here are some thoughts:

  • The NiZn AA cells are being offered in two capacities: 2500 mWh and 2800. When PowerGenix left the AA market, the company had never introduced its second-generation AA cell; the market was glutted with its green 2500 mWh AAs. Could these 2800s be the second-gen cells we were holding our breath for?
  • AAA NiZns offer users a fantastic new choice. NiZn cells deliver more lumens in several ways: First, by providing higher starting voltage; by providing higher ending voltage; by undergoing less voltage sag under load; and by allowing more current to pass through, thanks to extremely low resistance. All four benefits will be welcomed by users of AAA lights who don't wish to, or can't, use lithium-ion cells of that size and who, unlike AA users, have not been able to buy 3V primary lithium cells.
  • I wonder how these chargers compare to PowerGenix's old black charger (Fast charger, 3-5hr) and white charger (Quick "smart" charger, 1hr, independent channels).
  • The sub-Cs appear to be tabbed, not button cells.
  • Do you suppose that PowerGenix is the manufacturer?

Paul,

I got the feeling PowerGenix was never the manufacturer, they just contracted to have the batteries built. Now that they are no longer selling them the actual manufacturer is building and selling them on their own. Just my guess with no facts to back it up.

It does make you wonder about patent issues.

i have been using these batteries for six weeks now and they are doing good so-far

they are coming of the charger at 1.95-1.96v settiling at 1.88-1.90v i am using the black powergenix charger

i have only used 4 of the 8 batteries but i charged them all when they arrived

the unused batteries are still sitting at 1.75-1.78v

the other 4 have been charged once a week i have been using them in my fenix L0D tank E09 and a 2xAAA light that performs very poorly in NIMHs but very good on these

i am very pleased with these batteries and even if they were to last only a handful of cycles they are worth it to me

they were cheaper than i can get lithium primaries here in the UK and are saving me money with every charge

only time will tell how long they last i am definatly getting more

Interesting find. I too thought patent issues means PowerGenix was likely to be the only manufacturer. On the other hand Nickel zinc itself has existed for a long while and perhaps the patents aren't that wide. And perhaps some of the stuff like electrode seperator can come from the techniques developed for LSD. I see someone at CPF had Ultralast NiZn a couple of years ago, I don't see any discussion whether these are rebranded Powergenix or what. http://www.candlepowerforums.com/vb/showthread.php?274332-Ni-Zn-from-UltraLast

I just received 4 of each type (AA and AAA) for testing purposes. I will see what how they compare to my old ones.

12

What are you guys charging them with?

I have a powergenix AA/AAA charger but Sub-Cs?

My iMax B6 clones can't handle them.

13

I don't have the sub C batteries but you might try making an adapter to use the AA charger. I heard the FMA 8 can charge Nizn but it is in the $240 range.

14

Adapter time then..

Well these cells aren't anything to get excited about. So far at 1amp discharge they are testing out to have about 100mah less capacity than the Original PowerGenix cells. Just another case of false advertising.

Of the 4 I bought for testing purposes one tested out 300mah less than the Original cells but it came out of the package reading about 1.44v. Subsequent charge and discharge cycles has shown no improvement. The other 3 tested out at 100mah less than the Original.
