 Powers Things Longer than NiMh AA's November 16, 2009

I've been using these new nickel-zinc AA cells for about 2 months now. I'm impressed by how long they will power things compared to the usual NiMh cells.
I have a Magellan GPS unit that uses 2 AA's. It was probably designed for alkaline cells. New alkaline cells give a full scale battery bargraph, but freshly charged NiMh cells only make the bargraph hit about 80%. NiMh cells drop to about half scale after an hour. I only get about 4 hours with NiMh cells before the voltage drops too low and it turns itself off. Alkalines will last about 7 hours. The new PowerGenix NiZn cells give a full scale battery bargraph for about 3-1/2 hours, then it slowly drops until the unit turns off. My first test powered the GPS for 6 hours and 20 minutes, the second time it went 6 hours and 55 minutes. I left the batteries in the charger longer the second time I charged them, about 4 hours instead of 2. With my GPS, the PowerGenix AA's lasted almost twice as long as 2200mAh NiMh.
I have also used these in my Fuji digital camera that uses 2 AA's. They also last a long time, longer than the NiMh cells I have used in the past. The LCD display is also just a little brighter with the NiZn cells.
I have a little Grundig G6 radio that also uses 2 AA's. It won't turn on with these installed. I'm guessing that the radio is sensing the higher than usual voltage (about 3.6 volts) and won't power up. This is the only device I have found so far that isn't happy with the NiZn cells.
When these come out of the charger, they read about 1.82 volts without a load using my Fluke DMM. Of course the voltage will drop when current is drawn and as the battery discharges.
To sum it up, these cells act a lot more like alkaline cells with the higher voltage available. It takes a lot longer for the voltage to drop down to about 1.2 volts per cell when comparing to NiMh types. These start off at a higher voltage than alkaline and take a good long time to drop to the point when you need to recharge.
Give these a try, I think you'll be happy. I'll be buying more AA's and some of the AAA size when they are available.
Are these things really better? Or are they going to destroy your gear? December 7, 2009

Interesting technology....and somewhat scary if you look at the 1.8 volt figure. I got a 2 set of them to test. I have UW LED lights..and two large strobes that both take 4 AA batteries.
Until trying these, I have been using eneloop's (or the japanese duracell version)..which are very nice nimh's. The larger capacity standard rechargables work well in the strobes for the first 20 or 30 cycles, but eventually one of them will have charging/discharge issues and mess up the strobe firing and recycle time.
As they are higher voltage, there is the possibility that they would not work, or could damage equipment, so I started my testing with a simple 4 AA LED light that produces around 100 lumins. I charged the batteries and put them in light, and tested the light for one hour every week. The light was slightly brighter initially, but to my amazement, did not loss very much brightness over a two month test window (standard Ninh's drop off considerably after the two houra with this light). After nine weeks and 9 hours, I stopped the test (the light is supposed to last 6 hours with standard Ninh's).
Note: Capacity and discharge rate are related with batteries....faster usually means less capacity, slower means more.
Only issue I had was that this underwater light was not meant to be run for any length of time on the surface and there was some heat distortion of the plastic case making getting the thing apart really tough. My latter tests were with lights in water.
Then I installed them in a larger LED with 180 lumin light output....to my surprise, the light was the same intensity as with Ninh's.. as it turns out the unit has a voltage regulation system and and over temperature sensor.. which never went off. However, overall light output was much more consistent over the 4 hours I tested it. ( the time the mfg stated the light would be at around 25% output).
Having success with these two guys, I tried them out in one of my strobes. Ok, the recycle time is faster... and I suppose, if my camera could recycle faster and I could shoot fast enough to over heat them. However, I would find that very difficult to do, as one has to focus and compose the shot, and that takes time.
Strobes and cameras tend to do short duration, rapid charging... which is very stressful to batteries. Each of my strobes have three flash heads, and they recycle in around 2 -3 seconds and have any battery variation in internal resistance or capacity and they will not charge correctly. It has been common to shoot 40 or 50 flash images, and then have to reset the auto system due to a faulty charge cycle...
Note: These are underwater strobes, and essentially every image is a strobe pictures...so far this year, that means around 5,000 strobe flashes.
Recyle time, after a couple hundred flashes, takes less than an hour, compared with the typical 4 hours for eneloops and the best battery chargers I can find.
No battery I have used has ever recharged as fast or been as cool after recharging. That, by itself, would make it 5 stars to me.
I have tested the voltage after using them in the strobes for a day and have only seen less than a .1 volt variation.
I think the charging time issue is nothing more than the difference between a typical charge and the time it takes to completely charge dead batteris.. which hopefully no one does.
I happen to have all the test equipment necessary to do detailed electrical analysis... but these are just batteries and in the end, they either work better or they don't....
Nice product...

So, I saw a wonderful write up in a PC magazine about these, and I thought, gee, I'll give them a try as my little cannon camera chews up batteries and spits them out. I'm talking 25 flash photos and they are done, NOT very fun!!
The day I received these I plugged them in to recharge and read the instructions. It CLEARLY states that the quick charge will get them to about 80% and another 3-4 hours will get them to 100%, so I let them charge overnight. The next evening, while watching a movie, I placed a set in the camera and started firing off photos as fast as I could. The refresh rate on a short range flash was VERY quick, almost instant. On a long range flash, the recycle time would lag, depending on a variety of circumstances. (Did I let the batteries rest, how "fresh" were the batteries, etc.)
At the end of it all, and after my wife gave me enough looks like I was crazy, I fired off 250+ photos WITH a flash! (They were still alive, I just got tired of taking test photos!) That is 10 times the going rate of the alkaline batteries that it typically chewed thought. Even lithium batteries don't seem to hold up that long.
At the end of the day, I am VERY happy with this purchase. The test camera was a Cannon PowerShot A720 which only take two batteries at a time.
You won't regret your purchase for life draining gadgets!

I've been using these in my 580 EX flash and have had excellent results. Compared to the Ni-MH batteries I have been using, these batteries recharge faster and last longer.
Great in Digital Camera, childrens computer and flashlights November 6, 2009

Alkaline batteries are wasteful and just don't last long. NIMH and NICD don't have the needed voltage to run some of my devices, like my Olympus FE110 camera. Alkaline batteries go for about 50 pitures, CRV3 Lithium Ion don't fit in the camera battery compartment, and Fully charged NIMH, even eneloops show up in the camera as weak and only allow a couple of pictures before turning off. My alternative has been to buy the expensive non-rechargeable Lithiums. Functionally this works great but it is expensive and wasteful of resource.
The new Power Genics AA ZiNc batteries work great in every application I have tried them in. I've not had them long enough to know if they suffer from the discharge problem that NIMHs do, but I've had no problems of the slightly higher voltage causing any issues with my equipment. It's awesome to finally have a solution for our battery hungry FE110 camera. I can't wait for AAA's to come out!
