Digital Cameras Photo Reviews of Sanyo Eneloop AA NiMH Pre-Charged Rechargeable Batteries - 8 Pack
Customer Review: Great battery for photographers
Summary: 5 Stars
I purchased a set of 8 about 2 months ago, after becoming thoroughly frustrated with my much more expensive Powerex 2200mah batteries, that I had been using for about 1 year prior.
I use a Canon S2 IS, which goes through batteries like they're going out of style. I had thought the Powerexs would be ideal from what I read in their marketing, but I had some very bad luck with them. Out of the 8 Powerexs, one is now completely dead (as of 4 months ago, will not charge at all), and the remaining ones seem unable to hold a charge at all. Despite my best efforts to "match" them, a set of four will not last me a weekend of shooting (I shoot motorsports racing) without needing to be charged at least 4 times a weekend. Meaning I had to bring a car charger and charge in between races, often missing some races altogether.
Enter the Eneloops - so far, so good. They do seem to hold their charge extremely well, as advertised. I don't run any tests, I simply go by what I see. I charge both sets after finishing up a weekend, and let them sit until the next event. I can pull them out of the case, pop them in my Canon and shoot away, it is not uncommon for me to be able to shoot an entire weekend (2 days of racing) on one set of the Eneloops (although I always bring two sets just in case, that is never a bad idea, hence this 8-pack being such a great deal IMO). The fact that they work so well in such a power-draining application is testament enough for me, I will never go back to Powerex.
The Eneloops charge using my Powerex charger, I think you can use any charger that is made for these NiMh type batteries.
Customer Review: Great batteries
Summary: 5 Stars
I bought several sets of these batteries a year or so ago and have been testing them in our real-world environment in the house where my kids go through batteries almost as fast as they go through shoes. We use the batteries in wireless controllers for video games, digital cameras and other household electronics devices.
I let the kids treat the batteries as disposables (just that they need to bring them back to me when the get new ones from the battery drawer) and they change them as necessary. I take the used batteries, charge them up and put them back in the battery drawer for subsequent use. Keeping some ready-spares makes this entire process work. This also keeps the kids from having to wait to recharge the batteries since they have ready replacements.
This is all enabled by having rechargeable batteries that don't lose their charge while sitting in the drawer and this has worked very well for us.
We haven't measured how long they last, but the general feeling is that they last at least as long as typical alkaline batteries (and in some devices like digital cameras they last much longer).
I've recently bought more of these batteries -- not because we're replacing the old batteries but because I went to lengthen the pool of spare batteries so we can put these into more and more of our devices in/about the house.
Very happy with these batteries and strongly recommend that if you use batteries in your house you switch over to using these type of batteries rather than continuing with traditional batteries (for cost, environmental, *and* convenience reasons).
Customer Review: These batteries are great!
Summary: 5 Stars
I bought these batteries for use with my Canon S2 digital camera. I was having trouble with typical nimh batteries because I would charge a spare pair of batteries for use when the main pair died. But I was finding that the ones I charged a few weeks ago would be almost fully discharged by the time I would swap them. This was really annoying and pretty much defeated the purpose of having rechargeables... I had to use alkalines instead. But this new so called 'hybrid'/low discharge technology finally solves this problem. Of course it does not solve it completely because these batteries still discharge over time... just a lot slower, but at least now I know I have a pair of batteries that are at least 80 percent or so charged when I swap them. This technology was actually developed by an small independent company and licensed for use with all the major battery companies now. For instance, Sony is also utilizing it in their new batteries now. To me, this demonstrates how well it works.
So how does it hold up in real life? Pretty darn well, actually. I noticed that these particular batteries last really long in my Canon S2. I haven't had the problem of charged batteries being totally discharged by the time I swap them anymore. So if you're having similar problems with your older Nimh batteries, I would recommend giving these batteries a try. But don't feel limited to this brand, there are many other brands utilizing this technology and I've used other brands with the same great results.
Tip: If you live near a Fry's Electronics, they have a nice selection of battery choices that utilize this technology.
Customer Review: Eneloops - the only batteries I trust.
Summary: 5 Stars
I have been using Sanyo Eneloop batteries for about seven months now and they are, hands down, the best AA batteries that I have ever used. They last a long time both in use and when in storage. My flashlight, a Fenix TK40, is notorious for showing the limitations of various types of AA batteries. If high quality batteries aren't used, even brand new ones fresh from the package, the highest "turbo" light output setting on the TK40 will noticeably not be much brighter than its high setting. With ordinary alkaline cells, the turbo mode becomes the same as the high mode, but with Eneloop batteries, the turbo mode definitely blows away all the other settings. That is still true today, about seven months after I first bought the Eneloop batteries.
One of the best things about the Sanyo Eneloop batteries that isn't mentioned on the product packaging is that they do not leak. Alkaline batteries are notorious for leaking, even when brand new, so I do not suggest using them in any electronics that you care about. Sanyo Eneloop batteries just do not leak at all. Thus, I use them in all of my electronics that require AA batteries, including not only my high quality flashlights, but all my Nikon camera equipment (F-100 and SB-23) as well. After discovering Eneloops, I will never ever use an alkaline AA battery again.
Do yourself a favor and replace all the alkaline AA batteries in your house with Sanyo Eneloop AAs. All it takes is one alkaline battery leakage to ruin your electronics gear and thus the cost of the Eneloops is money well spent.
Yes, they are *that* good.
Customer Review: Do not order them from GE
Summary: 1 Stars
*UPDATE* 3 1/2 Stars
I just checked my email and amazon responded quickly and appropriately, if I could go back I would give this product a 3 1/2 stars due to the excellent customer service. And really this 1 star rating was just to get the vendors attention. But I believe amazon when they say they will look into this situation and hopefully for their sake and everyone elses it is an isolated one.
Also I have read many great things about this battery from several well known camera message boards online and the consensus is that these battery really work well and last longer than most. Sanyo also has 2700mah ones out now too, I'd like to try them but I will wait since I have these on the way already.
If you value your time and money don't open your wallets with these people. According to this the product is provided by "Sanyo Energy Corporation"? This is the most annoying circumstance I have been in since ordering online for years now.
The plastic package I received was torn open and taped back together with clear boxing tape. I did not pay a premium price to be given used or opened batteries. Even if they were not used I did not pay this price to be given batteries that could have taken a powerful impact to the packaging.
It would not have been that bad at all if it wasn't for knowing that someone PURPOSELY gave me a damaged/opened package. I am an understanding person and if it happened during transit that is one thing but it had a boxing tape on the package that was keeping it together is insulting and a horrible way to treat paying customers.
