  • Great basic charger, VERY LOUD HIGH PITCH NOISE!!!
Style: AA Size: 4-Pack Configuration: Batteries only
Great basic charger with no displays or other information. !!!Only complaint is it is VERY LOUD!!! There is a constant LOUD buzzing like a radiation alarm which changes to a LOUD pulsing buzz like a commercial fire alarm as charging nears completion. Sleeping is out of the question, even listening to tv or radio is difficult if chargers are charging anywhere in house. Still able to hear if charging in outdoor outlet on porch. Normally charge in my shed 50 feet away from house due to NOISE. I have 5 of these chargers both black and white from different years and all make same LOUD NOISE. Probably just my sensitive hearing as I was also unable to be within 20 feet of tube type televisions due to the loud high pitched noise. Be warned if you have sensitive hearing. ... show more

  • The Best Rechargeable Batteries!
Style: AA Size: 8-Pack Configuration: Batteries only
The Eneloop batteries out perform any other rechargeable NiMH battery - but only when charged with the Panasonic battery chargers for the Eneloop batteries. The Panasonic chargers (example: Model BQ-CC17) are sold on Amazon in packages with the Eneloop batteries. The key is that the Panasonic charger fully charges one battery cell at at a time, simultaneously, no matter how many batteries (1-4) are in the charger. Other chargers do not work this way and can mis-charge the batteries. Be sure to check your device compatability with rechargeable NiMH batteries (as the voltage range is slightly different). I use in flashlights, radios and remotes, and have had no issues, and save a lot of money vs disposable batteries! Also, NiMH batteries can be but into appropriate recycling bins at many home improvement stores or check for locations in your local area, but I have not had any Eneloop batteries fail so far, for years! ... show more

  • The best rechargeable batteries I've ever used!
Style: AA Size: 8-Pack Configuration: Batteries only
I've tried many different brands and have determined that these are far superior in performance in my experience. Both battery life and power are better than the competition. I use these (and primarily AAA) in my Kyosho Mini-Z cars for racing and can see a small but measurable lap time improvement vs. the lower-performance batteries. I won't buy any other brand now, I HIGHLY recommend these, worth every penny. ... show more

  • OUTSTANDING - eneloop = Consistent, Reliable, Durable & Capable. This Pro allows great runtimes on even the highest-drain device
Style: AA Size: 4-Pack Configuration: Batteries only
The eneloop Pro follows the long-standing eneloop tradition of NiMH batteries that run circles around most of the competition. This eneloop Pro battery is NOT designed for general usage, but rather high-drain applications. When paired with these high-drain applications, the Pro excels in a fashion that few other batteries can, giving you performance that other NiMH rechargeable and disposable alkaline AA batteries cannot provide. ------------------------- BACKGROUND & WHAT USAGE THE ENELOOP PRO IS INTENDED FOR Eneloop is considered by many to be the tour-de-force of rechargeable NiMH cells (much like Panasonic is with lithium ion cells.) Gone are the days where NiMH cells did not give performance that came even close to alkaline. Things like memory, low service lives, rapidly fading capacity, etc. are over. Today we have NiMH cells that can dramatically outperform the finest of disposable alkaline batteries and can be charged thousands of times. Over a 10+ year period, you can save thousands of dollars with a good NiMH setup. The eneloop Pro is eneloop’s (formally Sanyo and now Panasonic) follow-up to their highly successful eneloop XX series. Like the XX, the eneloop Pro is a SPECIALTY battery. It is NOT intended for usage with lower drain applications, and performs poorly when used for this purpose. However, when used in high-drain applications that tend to be brutal on the battery, the eneloop Pro gives unparalleled runtime that no alkaline can come even close to. ------------------------- THE STANDARD ENELOOP 2100 VS THE ENELOOP PRO: Which is right for you? Eneloop’s newest innovation is 4th generation NiMH cells. Like previous generations, eneloop is offering a standard-use and a high-drain model. These eneloop Pros use 4th gen technology, as do the standard eneloop “2100”. This fourth gen technology gives both batteries a very wide operating temp range, improved stability in output, slower self-discharge, and increases in durability. Eneloop Pro SPECS: -Capacity: 2550 mAh -Service Life: up to 500 recharge cycles -Rate of self-discharge: about 85% capacity remaining at 1 year of storage Eneloop 2100 SPECS: -Capacity: 2000 mAh -Service Life: up to 2100 recharge cycles -Rate of self-discharge: Over 70% capacity remaining at 5 years of storage -A substantial performance improvement with high-drain devices vs. the third gen THE 2100 --- The standard eneloop 2100 is designed to be a high-capacity battery that is capable of handling all but the worst of high drain devices. This battery makes substantial improvements over the third generation when it comes to handling higher-drain devices. It is ultra-low discharge (literally now it discharges SLOWER than many disposable batteries!) and high capacity at about 2000 mAh. This battery works great in both low drain and high drain apps. Additionally, with a cycle life of 2,100, this battery has serious longevity (literally the service life is four times that of the XX or Pro.) Because of this, most household devices should use this standard eneloop 2100. While it has a lower capacity than the eneloop Pro, the slower self-discharge and the ability to work better with low-drain devices will give better performance than the Pro with most devices. So if you are not using a device in which you constantly have to switch batteries out, the 2100 is what you want. The picture I uploaded shows a basic remote and Logitech wireless mouse; those devices get the best performance from the 2100s because they are not high-drain devices and so I use them exclusively in those devices. THE PRO --- However, there are some devices that are just plain brutal on batteries. These will benefit greatly from the Pro (or XX) design. For example, in my picture you can see a Fenix LED flashlight and a wireless gaming mouse. These devices put a world of hurt on batteries and run times are measured in hours. The eneloop Pro makes substantial improvements over the already outstanding 2100 in this sort of application. Cameras, audio players, high-output flashlights, medical devices, lasers, etc. will benefit here. So which battery you need completely depends on your application. I own 4 XXs and 4 Pros to go along with about 20+ 2100s. I use my 2100s for standard applications, and the XX or Pro for high-drain devices. ------------------------- WHAT I LIKE Like eneloops of the past, one thing that makes the brand unique is their advertising. Many battery makers advertise their batteries as having a MUCH higher capacity than they actually do. For example, I purchased 2500 mAh Tenergy batteries and brand new they only had a capacity of about 1700 mAh, and then rapidly shrank from there. I have had similar experiences with both Duracell and Energizer rechargeable cells. Eneloop guarantees each and every battery will meet their minimum mAh rating, and as a general rule all batteries exceed these ratings by a substantial margin. With these Pros, I purchased a 2550 mAh battery and I got a 2550 mAh battery. Additionally, eneloops do not rapidly shrink in capacity like other brands. Fives years or ten years down the line, these batteries will still work great if cared for. This longevity makes eneloop a much better value than inferior NiMH cells: spend a few extra bucks on eneloop today and enjoy their superior performance for years to come while simultaneously saving money. Eneloop also sends their batteries pre-charged (and they were charged by solar energy.) With the low self-discharge of the Pro, and the extremely low self-discharge of the 2100, you can use these batteries immediately after purchasing them. While the third generation batteries did a great job with colder temperatures, these 4th generation 2100s and Pros are outstanding. If you want to keep a flashlight in your car, these batteries are hard to beat given they work well in both hot-hot and cold-cold, and temperature extremes will not wreck your service life. ------------------------- CONCLUSION: WHAT I LIKE THE MOST Ultimately, there are two things I like about this battery the most. One, I save a ton of money over disposable batteries. I am talking thousands of dollars while simultaneously supporting environmentally friendly technology. Two, I get better performance from these eneloops and can use my devices longer. As of mid-2015, this is really THE battery to have for your high-drain devices (and the eneloop 2100 is really THE battery to have for your general-use devices.) So I highly recommend the eneloop Pro, as do I recommend the eneloop 2100 and eneloop as a company. If you are looking for a battery that gives you optimal performance with your high-drain devices, but would prefer an alternative to expensive lithium disposables, the eneloop Pro is the balanced choice of outstanding performance, outstanding value, and outstanding longevity. There really is no substitute. ... show more

  • Great for aviation headsets
Style: AA Size: 4-Pack Configuration: Batteries only
Bought these for my Bose preflight series 2 and they last a very long time. I can go a couple weeks(40+ hours flying) before I have to swap them out. They take a while to charge which is expected and when they die they die. No more getting an extra few minutes out of them. But that too is expected with the type of battery they are. Love them and highly RR them for any aviation headset. ... show more

  • Powerful and Strong

I have been buying Eneloop rechargeables for a while. They are stronger than normal batteries of the same size. More power, longer. Not perfect for every device, but makes some things work better.
