pro Rechargeable AA Batteries (4 Pack) 2500 mAh NiMH

These batteries are Great, lasting multiple hours of button mashing on Xbox controllers. And simply charging for around 4 hours when depleted. Have been buying these for several years, they usually last around 18 months per battery, charging roughly every other day of constant use. Much better and more economical than play/charge kits and buying one time batteries. I charge them in an amazon basics charger and usually but 2 packs of 4 so I can always have at lest 4 fully charged whilst using others in 2 controllers. I wouldn't buy any other batteries for high use scenarios.

I hesitated a little when buying a pack of 4 Eneloop Pro batteries because they felt a bit expensive, but they were recommended for use with the Nuki Smart Lock 4th Generation so I went ahead and bought three packs for use with my three locks. I charged them and put them in the locks on the 21 June. Over a year later the Nuki lock is telling me that they are still 66% charged. I can't say for certain that the Nuki is 100% accurate and I am probably not a heavy user of the door lock, but there are no obvious signs of the batteries going flat, so I think we can safely say that they don't self-discharge and they have plenty capacity for my routine activity. I never expected the batteries to work this well when I purchased them, but they deserve their reputation for quality.

These rechargeable batteries are mint. Works brilliantly in my smart TRVs and TV remote controlled. I only charge them once a year for the TRV and haven't had to charge the remote one yet. (Super) happy days! Yes, they do take a while to charge but I'm happy with that and I just need to think ahead. Not cheap but well worth the investment.

I’ve been using these batteries for a while now and they are brilliant! Last significantly longer than ordinary batteries in my DAB radio. They are so good in fact that I do not buy ordinary batteries such as Duracell or Energisers anymore. I’ve also purchased different sized rechargeables like these and they are equally as good. And the other major plus is that these batteries will not leak. If you want long running time and to save some money, definitely buy these.

Pretty damn good batteries is all I can say. They last a while and I use them for console gaming for long periods of time (

Overall I am "ok" with these batteries. They are of regular size, sometimes rechargeable batteries can be slightly off typical sizes and then cause fitting issues. But these have fitted into all the devices I have used. Even the sleeved type devices that have a tight fit. Be aware that all rechargeable AA batteries are rated at 1.2v and you do get a rare device that will not work at that voltage, expecting the more typical 1.5v of regular alkaline types. We have had one device that works but will show low charge, it isn't a low charge it is just the device is picking up on the lower than expected voltage. But it does work fine. I have got two decent battery chargers. Please see the photos I have included. Whilst they have claimed a minimum of 2500mAh for these batteries mine have ranged from 2445mAh to 2610mAh. Two of the four being under the minimum of 2500mAh. That was after two full cycles of discharge and charge, tested on two chargers. When these batteries arrive they are advertised as being pre-charged and ready for use, but they are certainly not fully charged. The resistance of these batteries is measured in milliohms, typically 20 to 80 milliohms being considered very good. If they are over 500 milliohms then they will not be good for high powered devices, like digital cameras. The highest I have seen , shown in a photo, is 116 milliohms for one and 48 milliohms for the other. So they seem decent enough. So far their life, capacity and capability is ok. Apart from two of the four that are below the minimum noted of 2500mAh. I had one of those in one hand controller of my VR headset and then the highest in another. The one with the lowest capacity, as expected, ran out first. It does make a difference. I would have expected them all to be close to or over 2600mAh, appreciating there will be degradation over time. So in that respect, as it is an advertised feature, then that is part of why I have reduced the rating by one star. The other reason that has contributed to that four star rating is the price. They are comparatively expensive and so the expectations of them meeting their advertised specifications is reasonable. As noted, overall I am "ok" about these batteries. I'll continue to use them and see, over time, how they last. I will edit this post as time passes if there is anything of concern regarding their use. Being just "ok" will probably mean I will look at other options for more batteries of this type. I hope this review has been helpful.

I needed new rechargeable batteries since the last ones i bought were years old. These new ones last ages in comparison. The charger is also fast enough for me and its nice you can charge one battery at a time.

Nothing is compared to these batteries.. best brand in the world!

Long lasting rechargeable batteries. Worth the higher price over some other brands.

Llevo usando las eneloop Pro AA desde hace tiempo en linternas, flashes de cámara, GPS y otros dispositivos de uso intensivo, y siempre han rendido de forma excelente. Con una capacidad real de 2500 mAh, son ideales para aparatos que demandan bastante energía o ciclos prolongados. Lo que más valoro es que mantienen la carga durante semanas sin apenas perder potencia, algo que muchas recargables no logran. Además, soportan bien los ciclos de carga: las tengo desde hace más de un año y siguen funcionando como el primer día. ✅ Lo mejor: • Alta capacidad real (2500 mAh), ideal para equipos exigentes. • Muy baja autodescarga, perfectas para tener listas en una mochila de emergencia o uso esporádico. • Gran durabilidad, incluso con cargas frecuentes. • Compatibles con cualquier cargador Ni-MH. 💡 Consejo: son algo más caras que otras pilas recargables, pero la calidad y fiabilidad lo compensan con creces. Si necesitas algo realmente fiable para uso frecuente o exigente, estas eneloop Pro son una inversión segura.

Work as advertised.
