Usually ships in 24 hours Core2Duoノートレビュー 's review (Bottom line....) 『Yes, they are rated in milliwatt hours not milliamps. However, my digital camera loves them since they are much closer in voltage to the 1.5v of alkalines, my portable ham radio loves them (uses 6 to get over 10 volts), my GPS loves them due to higher 1.6 volt vs. 1.2 of NiMh.
Almost all of my Nimh cells are in various states of degradation, won't charge, won't hold a charge for long etc. Nimh cells are terrible for self discharge and internal self-shorting. With the NiZn cells in it, my ham radio has been sitting for over a month and the display still says 10.6 volts.
I just order 8 more of these. You will love them too.』
(Perfect for use in digital camera!!!!) 『Who cares about the technical gobbledy goop!! I have problems with my camera when I am trying to take the next picture. It seems like it takes a long time and I miss the next shot. That definitely makes a huge difference to me! Try em, you'll love em! The "eco" aspect is just an additional benefit to our planet.』
(Marketing Hypes vs. Technical Facts of Nickel-Zinc Batteries) 『On first glance, the PowerGenix Nickel-Zinc Rechargeable Batteries seem to offer many advantages over ordinary rechargeable NiMH cells: higher voltage, higher energy density, lighter weight, longer cycle life, and so on. But before you rush to replace all your rechargeable batteries with NiZn type, let's examine each claim carefully to separate marketing hypes from technical facts:
"30% Higher Voltage" [FACT] The NiZn cell has a nominal voltage of 1.65V, which is 30% higher than that of a NiMH cell (1.25V nominal). When freshly charged, its terminal voltage is even higher at 1.85V!
"33% Higher Energy Density" [HYPE] The PowerGenix AA cells are marketed as "2500 milli-WATT-hour" (energy capacity). Most people may confuse this with "2500 milli-Ampere-hour" (charge capacity). But the data sheet for NiZn AA cell shows that its current capacity is only 1500mAh (this is verified by my own testing). It turns out that an 1500mAh NiZn cell actually contains the same amount of energy as a 2000mAh SANYO eneloop AA cell. - Energy in eneloop AA cell: 1.25V * 2000mAh = 2500mWh - Energy in PowerGenix AA cell: 1.65V * 1500mAh = 2475mWh
"30% weight and size reduction" [HYPE] The weight of each NiZn AA cell (25g) is about the same as NiMH AA cell (27g for eneloop). For certain applications, it is possible to use three NiZn cells (3*1.65=5V) to replace four NiMH cells (4*1.25V=5V). But doing so also shortens run time by 25%.
"Longer Cycle Life" [HYPE] PowerGenix claims service life of NiZn cell 'meets or beats' that of NiMH cells. However, technical data found on PowerGenix web site says NiZn cell is rated for 200 cycles (at 100% deep-discharge), shorter than the 500-1000 cycles cited for most NiMH cells.
"Longer shelf life" [HYPE] It is probably true that NiZn cell offers longer shelf life than Lead-Acid batteries (which are notorious for high self-discharge rate), but how does it compare against low-self-discharge NiMH cells? In the PowerGenix "Charging Procedure" section, it says you have to recharge the NiZn batteries once every 30 days!
In summary, the only verifiable benefit for PowerGenix NiZn cell is its higher operation voltage. However, even this may turn out to be a curse rather than a blessing. For example, the light bulb in a typical two-AA flashlight is only rated for 2.3V. But a pair of freshly charged NiZn cells produce 1.85*2=3.7V, which is enough to burn out the bulb. If you intend to use those NiZn cells in your digital camera, make sure the latter is still covered by warranty!
Finally, NiZn cells cannot be recharged using ordinary NiMH chargers. You have to purchase the special PowerGenix ZiNc 4-Position Charger, and be careful not to mix up different types of AA batteries and chargers. So unless you are desperate for higher battery voltage, it is probably not worth the extra expense and risk.』
(Best AA rechargable batteries) 『These batteries are the BEST. Any other rechargables should be replaced with this. These have greater power density than NiMH or NiCd batteries, which means more power, last longer, and lighter!! The weight difference is easy to tell. Putting four into a camera versus NiMH and you can easily tell the difference.
Voltage is closer to alkaline batteries that all AA devices are speced for (1.5 volts). These are 1.6 volts versus 1.2 volts for NiMH so you won't underpower your higher drain devices like cameras and wiimotes.
The best part is that they behave similar to Li-ions for charging and recharging. Charging is natively fast (about 1 hour) versus the long long time for the NiMH (using a fast charger for NiMH degrades the battery life). In addition, no memory loss effects like NiCd and power drain problems that NiMH are non-existant. Unlike NiMH I can charge these to full, leave them in a drawer for a few months and come back and they are almost still completely charged, while my NiMH are almost dead.
To add icing on the cake, these are easy to make (cost of production is less than NiCd) and they are extremely environmentally friendly: no heavy metals used and almost 100% recyclable (similar to NiMH).
These are the best AA type batteries you can get. Li-ion and AgZn cannot be made into AA or AAA type batteries based on cell chemestry (too much voltage). These are now the kings of the small rechargable batteries. Just as NiMH replaced the NiCd AA and AAA market, these will replace NiMH.』 『PowerGenix 4 Pack AA 1.6v High Voltage Nickel Zinc Rechargeable cells 2500 mWa』

They look very cool with the design and the blue light, but the sound quality is terrible. I wanted a pair of good-decent speakers to take with me when I travel, I thought these would be perfect, they are compact and they come with a great carrying case...I didn't think that they would sound as bad as they do...

Core2Duoノートレビュー 's review (it passed the first test) 『I received the rain cover on Wednesday and Friday night I had to photograph a football game in the rain. It worked. I need to use it more to be able to feel more comfortable with adjusting my camera setting while it is on. When I first saw this cover I thought, why couldn't I have invented this? It is truly a "simple" idea and all I can say is, I spent 4 hours in non stop rain and my gear did not get wet. I am glad that I bought it.』
(Recommended) 『I have the much more expensive Kata E-702 Large Digital SLR Camera Raincover, but I like this product better. It's very simple, with an elasticized end that just fits over my Canon EF 200mm f/2L IS USM Telephoto Lens for Canon Digital SLR Cameras, which has a pretty large diameter (too large for the Kata).
The soft material means it can be folded up very compactly - much more so than the rather stiff Kata raincover. It's as easy to pack as a plastic bag, and easy to slip over your camera and lens.
I suppose it might not be as waterproof as the thick plastic Kata if you're out taking photos in a hurricane. And the Kata has the advantage of being transparent, so you can read your LCD screen through it. (Though realistically, if it's raining, you can't see that much anyway.) All in all, I find this a much more useful product, not to mention cheaper. My thanks to whoever invented it. I love it.』
(Camera Rain Cover) 『Great product for the cost. Saved me potential damage to my Canon Rebel Xti, when a surprise rain shower came upon me.』
(second review) 『This is my second review for this product. I did not give this product a favorable review initially. Because of this, the seller contacted me and stated that I should have contacted him first. He then explained how he felt that the product was worth the money and asked that I remove my negative feedback. I have to be honest, I was offended that I was asked to remove my opinion. But in an effort to be fair, I followed up and agreed to change my feedback IF my opinion changed. This cover was purchased as a gift. Let me repeat, I am NOT a camera or camera equipment expert and I never said this was the most expensive cover. I gave the item as a Christmas present. Upon receiving the item, we realized that it came with no information or instructions either on the package or inside the package. I am still disappointed with, what I feel, is a "cheap" product. Again, I never said this was the most expensive cover, but I do feel the price was a bit much for what I received. After the gift was received we discussed my negative feed back and I asked what he thought of the product. He agreed that it did seem a bit on the "cheap" side and said he felt there should have been some information about the product included. The recipient has only been into photography for about 2 years so is also not an expert. Which is why the recipient is going to use the product and see how well it holds up and works. I am hopeful that it will prove to be a great product despite what my current opinion is! Unfortunately, I feel it necessary to keep repeating that this is MY OPINION and I am not in any way claiming to be an expert about cameras and their equipment. I do not want to hear back from the seller. While I appreciate his wanting to explain why its a good value, I do not appreciate his asking me to change my opinion. Information about the product should have been included with the packaging. I thought I had explained in my initial review that this was only my opinion.』
(Great price, great product!) 『I purchased your camera cover recently and I was extremely happy with it. My husband and I had taken it to Ireland for our vacation (to be used on my Canon XT.) I knew it was supposed to rain so I purchased the cover in advance and boy am I glad I did! Not only was it easy to use, the cover worked like a charm! We took some great photos we would have not been able to take without it. Thanks for making our Ireland vacation a memorable one!』 『
