Size: Pack of 4Verified Purchase

Purchased June 10th 2017. Hopefully it was just a bad batch
Bought these and the double AA batteries, which haven't had any issues. The AAA batteries are the only ones that I received, that has given me problems.installes in a new Samsung remote. Pics are really worth a 1,000 words. Hopefully the manufacturer monitors this reviews.

Updated 1/19/2019

I called Amazon, told her my experience with these batteries. ( she saw my review of these batteries batteries. She credited my account for these batteries. She couldn't reccomend a different battery line, or swap out these batteries. She did say u would have to order these or another brand that Amazon Carrys. This was taken care of within weeks of purchasing these batteries. I didnt know I hadn't updated the review.

The remote was cleaned with white vinegar and was air dried. It still worked. Thankful for small favors. Lol

Beware! This AAA's are only 1.2 volts!!!

Reviewed in the United States on May 18, 2020

Size: Pack of 4Verified Purchase

When I saw this set of Panasonic rechargeable batteries I decided to buy them due to the reputation of the brand name--for the most part. However, as soon as I opened the package I noticed that each battery had only a charge of 1.2 volts max. instead of the 1.5V that every freaking AAA comes with! When I tried to use them on my remote, for instance, I immediately received an warning light indicating that the batteries were low, even though they have been fully charged! So I ended up returning them for a refund and go with traditional alkaline (non-rechargeable) ones instead. Just for anyone's reference, the majority of regular batteries (AA's, AAA's, C's, D's etc.) stop working almost as soon as their charge falls below 1.5 volts. I've tested numerous worn out batteries of different sizes with a multimeter before disposing of them and I always noticed that they still have between 1.2 to 1.4 volts left in them! This is information that I'm sure most battery companies don't want you to hear :)

Junk knockoffs..

Reviewed in the United States on August 20, 2020

Size: StandardVerified Purchase

These are junk knockoffs.. 4 of the 8 cells I purchased have failed already in only a few hours use. Won't charge, voltage is low. The cells are wrapped with a sticker that peels off ~ easily; this is not how real commercial cells are made.

I'm throwing them all away. I certainly do not appreciate being ripped off like this. Further, using these for lighting while cycling at bight, when a cell goes out the lighting fails. It's dangerous.

Shame on these people..

Beware they could be sending you old batteries that have sat around for years

Reviewed in the United States on October 30, 2019

Size: StandardVerified Purchase

I bought an 8 pack of Eneloop aaa's this year for my black diamond headlamp when I go camping. I camp 15-20 times a year and need batteries to last. I collect wood in the dark,cook in the dark and sometimes come back from hikes in the dark. These disappointed me cause they tend to last 3 nights or less and I have had my 3+ year old Energizers last 5 nights! The Eneloops should be lasting longer they are newer and have high 800mah output compared to 700.

Eneloop also has a detailed graph on the back of their packaging of these batteries that claim after you fully charge them that they retain 90% of their charge in storage for the first year,3 years 80%,5 years 75% and 70% after 10 years. I've put all 8 batteries (2 at a time) in my Roku remote after I fully charge them and they all say 70% on my battery indicator. That's a load of crap saying these batteries maintain 70% of their charge after 10 years when all 8 of mine are only charging to that capacity and I haven't even had them for more than 8 months! I would not recommend anyone buying this brand of batteries when they are being outperformed by cheaper and older batteries that have already been used over 100 times and still work better than eneloop.

UPDATE: I've also field tested them in my Black Diamond and Energizer headlamps in high 30 degree temps at night camping and the light output was drastically different! Both sets of batteries were fully charged before i left to go camping and the energizers are a lot better than Eneloops.

These are "rechargeable" but they don't hold a charge

Reviewed in the United States on August 18, 2018

Size: 12-Battery PackVerified Purchase

It's often been said that the definition of insanity is doing the same thing over and over and expecting a different result. By that standard, my continued purchase of these batteries means that I'm insane. The issue with them is that they simply don't hold a charge. As in, they croak after a few days in a TV remote. Mind you, I'm using a Panasonic NiMH charger to charge them so there shouldn't be any issue on that front. Well, there is, and it is that Panasonic Eneloop AA and AAA batteries just don't hold a charge. I picked up a few packs of EBL NiMH AA and AAA batteries.....they take a very long time to charge and a very long time to discharge. My suggestion is to stay away from the Eneloops unless you are looking for a second job as a battery charging attendant.

Poor at holding charge

Reviewed in the United States on January 10, 2021

Size: Pack of 4Verified Purchase

This is my third package (first rotten ones) of Eneloop rechargeable batteries purchased on Amazon. First two packages were purchased over a year or two ago and those older ones function well. This third package are almost useless. They hold a trifling bit of charge before needing to be recharged. On a tiny device that normally needs a new battery once every 2-3 months from daily use with GOOD Eneloops - now needs a new battery about every 3-5 DAYS with the BAD Eneloops (at best). And when they run out of power - they are dead as a doornail. My device can't even give me a warning flash that the battery is low with these - they're just dead. Wish it wasn't past the return window. Test yours out thoroughly when they arrive - so you can return if they are losers. These are probably fakes that are made to appear to be authentic eneloops. Highly disappointed - but that's Amazon - they'll sell anything - from anywhere - in any condition - to make money.

Well after a lot of research due to expense of betting batteries I went with these very, very High Rated brand name rechargeable Eneloop batteries. I use them in a " digital voice recorder " and they drain down very fast. I though..... maybe because I just got them? Have recharged them all the way up and they drain down way to fast in this low battery drain device. Now in a LED flashlight " uses 3 batteries" the time between having to charge is also Way to Fast compared to the high reviews I read. Confused on what the issue is. Very confused.

siempre me han funcionado bien y han sido muy favorita. este paquete de 24, salió más barato de lo esperado y son de las que más se usan en la casa, controles de televisión, Set top box, etc.
No he utilizado todas las pilas, pues las compre como repuesto y para que no falten, pero las que he usado saliendo con la misma calidad que esperaba que salieran. son duraderas y de las pilas que tengo, incluso de hace unos 4 o 5 años, siguen funcionando bien.

There is no substitute

Reviewed in Canada on August 19, 2017

Size: StandardVerified Purchase

There's a reason these are the benchmark for Low Self Discharge batteries; they're that good. They are now the only batteries I buy. I use them for everything ... wireless headphones, headlamp, remotes, bike lights, portable clock - anything that takes a AAA. I have bought Amazon Basics LSD batteries in the past and while they are good, these definitely do last longer and you get potentially 2,100 charges as compared to Amazon basics 1,000. In the long run they are worth the few extra bucks.

I charge mine with a LaCrosse charger and usually use the 350 mA charge current (Anything below 750mA is safe for these)

Do not buy.

Reviewed in Canada on February 11, 2020

Size: 16-Battery PackVerified Purchase

What can I say about these batteries? I was expecting a way better product. Seven of the sixteen batteries failed within a week. They show "Err" on the battery charger and are beyond recovery. After two weeks of use many of the remaining cells show little ability to hold a charge and have a capacity of less than 40mAh. These batteries were fully charged before deployment and were used to operate small ornaments, each with 3 LEDs - not a challenging load. None were allowed to fully discharge before cycling again through the (miboxer) charger. I had purchased 12 EBL batteries at the same time and all of them continue to function ad expected. I'm quite disappointed with the Eneloop batteries. They are highly rated but my experience was different and I cannot recommend them. Maybe just a bad batch. I threw the first one in the garbage not expecting so many to fail now I can't even return.

Very high longevity

Reviewed in Canada on January 24, 2020

Size: 24-Battery PackVerified Purchase

I bought some of these batteries 10 years ago and most of them still perform very well. They can stay charged in storage for a long time without loosing their charge. The reason I didn't put 5 stars is because they arrived uncharged, completely empty. It took about 6 hours per set of 4 to charge. I didn't try this batch yet so I hope they will perform at least as well as those I bought 10 years ago but the fact that they arrived uncharged and I don't know how long they were in that state makes me suspicious. I use the first batch in everything, my Panasonic cordless phones, all my remote controls, mice, etc. This is an excellent product and I highly recommend it.
