Update 11.04.14 - Be aware of the Chinese knockoffs of Eneloops, they are nowhere near as good as the Japanese ones. The Chinese Eneloops die around 500 cycles while the Japanese ones continue running over 800 cycles. Try to get the Japanese Eneloops if you can as they are generally more reliable. Hopefully Amazon will continue to carry the Japanese ones.
Update 9.27.14 - Did a battery test of the pack i used and the battery that was fully discharged still managed to produce the necessary mAh and was slightly higher than the others. For some reason or another only 2 batteries was slightly higher (maximum of 39mAh difference) capacity so it's unclear as to the reason behind that, though 2 of the batteries were numbered and were discharging for a bit in a tv remote and then in a flashlight so it appears that the more often you use them, the more mAh they will produce. That seems to be the case with any NiMH battery, it's best to use them versus leaving them in storage for a long time. So it is highly recommended you buy what you need, if you need some extras or 'in case' make sure you cycle them through and not just leave them sit in storage for several years without using them. Since basic Eneloop batteries have high recharging cycles, it's better to discharge them fully a few times to break the battery in and use them a few times in a high drain device to keep them working. They don't have to be drained fully, 40% discharged (that's 40% charge left in the battery) is the best which will help keep the mAh up and fully discharging them every once in a while to prevent overcharging and voltage depression (or memory effect) which NiMHs are highly resistant that or even don't even have that problem such as the company has stated, they mostly are susceptible to overcharging though which does cause the voltage depression phenomenon which acts like there is a memory effect.
Regular, cheap NiMHs or just cheap NiMHs in general lose their mAh capacity over time and even when they are just being used.. avoid those types. Eneloops appear to be the best, AmazonBasics, Duracell and most Energizers are good alternatives if Eneloops are not available but avoid most cheap chargers and find a smart charger with Negative Delta V, overheat protection, and capable of charging any number of batteries. The Panasonic sounds like a pretty good, cheap alternative and get the ones with the batteries as they are a better deal. I plan on getting some Eneloops Pro that comes with one of these chargers but with the basic 2100 cycle Eneloops, it's probably not needed to have the higher capacity ones but they do last a bit longer on a single charge for critical usage. I can't wait to see how long these batteries will hold up during the test of time. Using rechargeable Duracells, they hold their charge for a very long time.. almost 10 years in service and only has a loss of mAh capacity but they still perform for a pretty long time, can still be a few months sitting idle while the Energizers i got around the same time (the 2500mAh ones) lose their charge within a few weeks, but can be recharged and then sit for awhile on the charger and they will get a bit more charge out of them but those will primarily be used in tv remotes and other really low drain devices where i don't mind recharging them every few weeks. Anyway the Eneloops perform well and seem to have a long life ahead of them.
==
I got the 16 pack and also heard that these batteries are similar to the AmazonBasics which claims they do not lose capacity when over discharged. While i am still in the process of finding out whether the battery that i subjected to an over discharge has lost mAh capacity it held it's ground from zero volts. With the battery fully discharged (or near death) i threw it in a remote with a charged Eneloop and it was showing a sharp decrease from 0.9 volts to 0.4 volts. Then the battery stabilized itself there with no decline or any indication that there was cell reversal (which charges the battery in reverse). I wasn't sure what to make of that, but i have concluded that there is indeed some over discharge protection. I decided to put more strain on the battery and threw the batteries in a flashlight, to my amaze the flashlight, dim as ever was able to light up. I let the batteries sit in there 15 minutes to see if the light would stop working but even after 15 minutes the light was still going. I took the battery out and it was registering just under 0.1 volt. While i was being distracted that i didn't have enough time to unscrew the flashlight to get to the battery i threw the the batteries back in the flashlight and checked it again after 5 minutes. It was still showing just under 0.1 volt. No reverse voltage.
It appears that after my test these batteries do not reverse charge and is somewhat resistant to over discharging, which would be fine mixing a pack of these batteries in different devices. Even after my tests i wouldn't recommend mixing the batteries as i am sure even once these batteries reaches 0.7 volts, they start eating up cycles. I have no idea whether keeping the batteries in a discharged state and using them would start reducing the life of the battery or that they would take up a few cycles, but i still need to test the mAh of the batteries to see whether the one i over discharged has lost capacity, which is the other claim from AmazonBasics and i think Eneloop advertises the same thing. It would also make sense why the AmazonBasics has lesser rated recharge cycles then Eneloops. Eneloops do not advertize they can handle over discharging and it makes sense why they don't want to. They want to make sure the consumer gets the most recharges out of their batteries which would make these batteries the number 1 rechargeable battery company of all time.
Which is why i highly recommend these batteries. These batteries will last a very long time if you take care of them. You probably will never need to buy new batteries as if you were to charge these batteries daily (or discharge them daily) you would still get about 6 years out of them which is hard to come by with rechargeables that are constantly being discharged and recharged with minimal rest. I'm going to give these batteries another test which will only be 2 AA in 100-130F heat. I have had some people say they don't want to switch to rechargeables because they think that heat will ruin the batteries. I beg to differ, while the batteries might not last as long.. with this other test these batteries should have no problem being able to work in the heat and while it might reduce these batteries life to about 2-4 years, it's far better than replacing the batteries weekly spending more money than what you would on rechargeables.
On a fresh charge opened from the package, while it was difficult to understand the date code of the batteries "14-05LJ" and "14-0400" I assume the 14 means the year which would mean these batteries were produced earlier in the year, but again it's not easy to tell based on the letters. If anyone knows that information, leave a comment. Back to a fresh charge from the opened package (literally) I am a bit disappointed from Amazon sending me a product that has been opened, it's possible that it opened during shipping but i did get 2 different date codes on the batteries, but it also appears that Panasonic shipped them this way too. I will say that Panasonics packaging is left to be desired, they could have packaged the 16 pack in a more secure packaging or give consumers a plastic container with the batteries in them but i'm not complaining.. eventually i will put them in a more secure container but for now, the package is holding with some tape.
On a fresh charge, these batteries were able to give my phone a 92% charge using a USB charger, powered by AA or AAA batteries. Provided that if i never did charge the batteries i wouldn't have gotten the 92% charge but after recharging the 4 set of batteries i used already, i will see how much of a charge the batteries will put into after a full discharge. I have noticed a few complaints about the batteries not being fully charged and while there are a few different reasons why there is a rare chance that you would get a set of batteries that are discharged or will not recharge correctly. It is a fact of life and happens with any kind of product out there on the market when they are massed produced. It's also rare that businesses would actually strive to lower that percentage because anything with a 1% defect rate is acceptable loss limits when dealing with a world that strives to have profit over making that 1% happy, though many companies do have exchange policies if you received a defective product.
A couple of things to think about. These are 1.2 volt batteries and while most devices that require 4 batteries will function fine with 4 NiMH batteries, any higher than that and you would start to see a declining performance or even if your product will function with 6 1.2 volt batteries versus the 1.5 volts. The other thing to consider though with that is alkaline batteries are about 50% charged at 1.2 volts so these devices might run fine even with 1.1 volts but that really depends on the device. Recently, i have found that some devices can ask for more than 1.2 volts and can be considering the NiMH batteries as dying or low but it greatly depends whether the device is detecting the voltage or the mA being produced. With that being said, before assuming that these batteries do not come charged consider these things first that the device may ask for more voltage, your charger is a cheap model or does not function properly, batteries only carry 50% of rated capacity from the manufacture which a refresh is in need or that you require more than 4 batteries and the device will not function properly under the 1.2 volt batteries.
With that being said, before you assume these batteries are at fault, try it in a different device or in a flashlight that only requires 1-3AA first after refreshing them a few times and see how they work. With the initial use, i managed to charge my phone up to 92%, it was lower than the http://www.amazon.com/Duracell-Rechargeable-Batteries-Duralock-Technology/dp/B00DSYFAEQ which managed to charge a few devices without being depleted, those are rated at 2400mAh, still on first use these 2000mAh hold up really well and are ideal in just about anything. While there are some devices that won't work well with 1.2 volt batteries and it's not a good idea to use rechargeables in smoke/carbon dioxide detectors or anything really vital to your safety i recommend using http://www.amazon.com/Duracell-Alkaline-Batteries-Preserve-Technology/dp/B00EDK4HXY for high drain devices that often need replacing, for the smoke/carbon dioxide detectors, the classic Duracell battery also rated to last 10 years will work just fine.
Other than that, these batteries hold up really well and i will post back when i got more info on the set of 4 batteries i have been testing with and will soon test another set out in my 2D Maglite (using D spacers of course) to see how long they hold up for.
I purchased this product as a better alternative to the Sony CycleEnergy charger I purchased last Christmas at a B&M store in Germany for €29.99 (about $37 USD). The biggest disadvantage I had with the Sony CycleEnergy charger is that it required me to always charge batteries in pairs, which ended up becoming problematic after noticing that the batteries don't always charge equally. I would charge the batteries until the LED light would notify me that they are ready to use, yet after inserting them into my high-power devices the batteries would already read one to two bars lower instead of indicating all the bars for a full charge. At the time I also only owned two rechargable AAA batteries, one which was used for my wireless laptop mouse and the other for a Bluetooth stereo remote. This also turned out to be a problem since the wireless mouse would drain the battery very quickly whereas the battery in the remote would barely lose its charge, which in turn would force me to charge a near dead battery with an almost full battery.
It was at this point that I started looking into a better alternative for charging my rechargable batteries, and after a bit of research I came across the Panasonic BQ-CC17 "Advanced Individual Battery Charger". The reason I chose to go with this specific brand and charger was because it has excellent ratings, the great price, and most importantly allowed for individual cell charging.
I cannot express how pleased I am with this product, and I highly recommend this product without any hesitation to anyone in need of an excellent battery charger! The convenience factor alone of not having to charge batteries in pairs makes this product a well worth investment in my opinion. I am also shocked at how affordable this battery charger is compared to the Sony CycleEnergy I purchased, as I only paid ~$20 which included 4 AA batteries that sell for ~$14 if bought without the charger. I practically could have purchased two of these Panasonic chargers for the price that I paid for a single Sony CycleEnergy charger!
As far as my experience with the battery indicators on my high power devices, they finally indicate a full charge when inserting the batteries into the device! Which tells me the reason as to why it showed one to two bars less on my previous charger is because the charger was set on a timer and one of the two batteries must not have been getting fully charged during the process. The BQ-CC17 has also bee compatible with all my other NiMH rechargable batteries, which so far include my Sony CycleEnergy AA and AAA, Duracell AAA and AA StayCharged, and Energizer Recharge Plus AA.
Another plus for folks such as myself is that this charger works outside the U.S., as the packaging indicates 100-240V 50/60Hz making it world wide compatible as long as you buy a plug converter (can be found as cheap as $1, though I would recommend paying a few extra bucks for a better quality and safer product).
The only con I found with this product initially was in regards to the LED lights, not that there is any performance issue with the lights themselves, it was just impossible to even know they existed until you plug the charger in and charge a battery. When the item first arrived I was under the impression that I had received the wrong charger as I couldn't see any LED lights on the charger nor did I find any mention of them on the packaging. I had to go back to the product page on Amazon to ensure that I had purchased the right product and properly read the description to include LED indicators. It wasn't until I used the charger for the first time that I was able to spot the LED indicators, as they are hidden behind the white plastic case and near impossible to see without charging a battery. Overall I think it actually makes the charger look more aesthetically pleasing with the LED lights hidden behind the case, I just found that initially it created some confusion since some of the pictures on the product page show the little green lights which makes it seem like the lights are featured externally on the charger. Perhaps it was just me, but I figured I'd mention this just in case anyone else is a bit confused when they can't find the LED indicators as the thought of them being hidden behind the casing never even crossed my mind.
Another thing I want to mention in regards to these Chargers is that it appears the only difference between the BQ-CC17 and BQ-CC17 "Pro" is the color. According to the product information from each charger, everything else appears to be exactly the same. So unless you prefer a black charger over a white one I recommend that you don't get hung up on the extra wording of "Pro" and instead purchase the BQ-CC17 charger that comes with the 4 AA batteries as that's the best bargain.
My purchase was shipped by and sold from Amazon.com, which arrived in the retail packaging displayed in the picture of the product page and was fairly easy to open. The 4 AA batteries including in this pack came pre-charged and were ready to be used upon arrival. In my opinion this charger is the best in it's price class, I'll even go as far as saying better than all of the more expensive models I've bought in the past.
Short Summary:
-Charges batteries individually which results in proper battery charge, unlike those chargers set on timers or requires charging in pairs.
-Great price, especially if you purchase the model that comes with 4 pre-charged AA batteries.
-Works worldwide (100-240V 50/60Hz) with additional purchase of plug adapter/converter
-LED lights are hidden underneath white casing, will only turn on when battery is being charged
In conclusion, this is the best rechargable battery charger I have ever used, I cannot recommend this product enough!
I save a lot of money especially with my son constantly going through AAs with his game controllers. I keep enough charged so we always have some ready to go. Batteries are a terrible thing for the earth, this reduces the waste tremendously and if we all use them, it would have a huge impact on the environment.
I did have a charger that worked okay, but this is a more modern one with some extra convenience features.
The ideal part is that you can mix and match AA and AAA and the 4 slots charge individually and have their own led that shows green when charging and the led turns off when full. You can even charge one battery by itself.
That becomes obvious very quickly when you pop in 4 rechargeables.
When I did, one light went off almost right away (the battery was apparently still almost full) , 2 went off about 2 hours later, and the last one took about another 2 hours.
There are some people on here that go into all kinds of technical details about chargers, and that is a great read for those who care and are interested, but for me this is just a plain, simple, quality product from Panasonic/eneloop.

The charger is fine, has an individual status light for every battery. It can also charge individual batteries, which is nice. Many chargers only take pairs or more.
The only downside so far is that it doesn't have the trickle charging mode my old charger used to have. It shouldn't be a big deal with high quality batteries that retain their charge well, but still it's something I wish I had.
The batteries are typical Eneloop batteries. If you used Eneloop in the past, you know what you're getting. They're definitely pricier than some of the other brands, but they're also considerably more reliable. I have 7 or 8 year old Eneloops still in use, which I can't say for some of the cheaper other brands. Hope they didn't get worse over the years, and that these ones will last well into the 2030s.
