Amazon Customer: I used to buy Energizer rechargeable batteries and for a LONG time they did work. I used them in speed lights and would recharge them every day and wouldn't have to change a set forever.

The last at least couple of years there was a massive drop off in quality. I'd buy a set, fully charge them, and the next morning I'd put them in my light and it would say less than half charged. One good use and they're almost dead. It was like the company got sold off and they were making these in Mogadishu or something.

Finally got these batteries, and after a charge they last a LONG time and when I put them into my photo equipment they are actually charged. Still have to see how long they last before starting to lose power but so far these are the best and most reliable batteries I've purchased in years.

Kindle Customer: I use these in my battery-powered amps for practices and gigs. Each amp takes 6 AAs (Vox 5W and Roland Bass Cube) and I get at the very least 10 hours out of each charge (likely far more, but I keep forgetting to note when I've charged them and how many hours I've used them). I obviously don't track them very closely, but the batteries do seem to not lose charge by sitting around (the Vox had been sitting around much more than the Bass Cube).

Using these batteries has made making music so much more convenient, as I don't have to worry about wasting batteries and can use the amps whereever I want to. I'm also looking forward to switching out all of our remotes' batteries to Eneloops.

The only drawback I've found so far is that the Eneloop chargers only hold 4 batteries, so I bought this package after buying a larger set, for the second charger.

A: These are good NiMh cells, and I don't really have any complaints. However, the cells don't really hold "70%" of it's charge for long. The cells were lightly used, charged fully, and probably around 25%-50% charge after less than a year. Keep in mind they were used and I didn't do any scientific testing, just what I noticed. The cells do hold a good enough charge that I don't worry about storing them though. I've used these cells in everything from flashlights sitting in a hot car to solar lights sitting in 115°F+ with no issues, and they're still going strong. These cells aren't the best out there especially for the price. I prefer a certain Swedish furniture store's batteries more than these. The biggest thing for NiMh is just make sure the cell is made in Japan.

Arturo O.: Hasta el momento tengo utilizando una en un mouse inalámbrico, lo tengo prendido la mayoría del día y sin fallas.

Otra en un reloj y una en una maquina para cortar el cabello y sin problemas.

Nate: I have used their product for the past six years. I only purchased this unit because I forgot the others while traveling. ;>(
These batteries hold their charge for months on end. I use them on a wireless sound system mic. I can let the batteries stay in the mic for a month. And, when I'm ready to use the batteries, the run like new batteries.
It would be nice if they could recharge in an hour or so. But, it takes about 4 hours to charge them from dead. These were the five year old batteries. I can live with that. I always have a fresh set waiting.

Fue entregado en un sobre con interior papel burbuja, limpio y sin rastros de uso.
Estas pilas las probé usando un Wii Remote Plus con vibración activada y volumen 10, jugando Super Mario Galaxy, que utiliza casi todo el tiempo la mayoría de funciones de este control; acelerómetro al girar, puntero infrarrojo para apuntar y lanzar star bits, vibración cada que giras, caes al suelo, etc., volumen cada que recoges star bits, además de utilizar el Nunchuk y el acelerómetro del mismo. Prácticamente es el uso más intensivo para el Wii Remote, dejando de lado solamente el giroscopio que no se usa.

Mientras más veces he probado estas pilas con los Mario galaxy me he convencido de que no puedes confiar demasiado en la detección de carga del menú de Wii, ya que un día puede llegar a las 3/4 barras llenas y al otro día durar un rato con las 4 barras llenas, incluso en el mismo día puede bajar y regresar a la misma barra por mucho tiempo hasta que decida bajar de verdad, quizá se deba a que las pilas son de 1.2 Voltios, mientras que las alcalinas con...

Midnight Distortions: Update: 6.17.15 - The best just got better, Eneloops can hold up to 70% after 10 years! As indicated on their official website, it's unclear if fully charged Eneloops can hold up to 70% after 10 years or the latest set of Eneloops are able to hold up to 70% after 10 years. It would be impressive if this were true, but after 10 years i think the cycle number would greatly be reduced as testing showed less cycle usage on older cells. Still NiMH technology can be impressive as i have 16 year old cells that work in a clock for a couple of months. It'll be interesting how an aged Eneloop would function.

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...
