BONAI AA Rechargeable Batteries 8-Pack, 2800mAh High Capacity 1.2V Ni-MH, 120...

Good price and seems like a good quality batteries. Initial assessment showing 2500mah... May increase to the max after few uses.

I’ve been using these rechargeable AA batteries exclusively for several years now—there are no conventional disposables left in our home. The build quality is consistently excellent, and I’ve never encountered any issues with leakage or chemical discharge from the casings. What really stands out is their long-term reliability. Every set has been recharged multiple times without any noticeable drop in performance. Even in outdoor use, they retain their charge impressively well. One set powers an external weather station and only needs to be swapped out about once a year—remarkable for AA cells exposed to the elements. The 2800mAh capacity is solid for this size class. While I would love to see a higher capacity option, I understand that the constraints of the AA form factor likely limit that possibility. In short, these batteries have become a dependable part of our household tech ecosystem, and I wouldn’t hesitate to recommend them.

Have been using rechargeable cells for years starting with NiCd cells in the early 90’s through NiMh versions till now. Discovered low self-discharge cells from Energizer and Uniross about a decade ago. I was really impressed as generally rechargeables though useful was not that great due to the discharge characteristics and were flat before I knew it. The technology was too expensive at the time though and I didn’t convert. I finally converted a year or 2 ago when prices become more reasonable. Brought into Sanyo/Panasonic Eneloop cells and have been using them since. Recently, I was looking for higher power versions, but found that the “Pro” variants to be prohibitively expensive. Found these on the recommendations tab and decided to give them a try. I purchased two 24 packs of AA (2800mAh) and also AAA (1100mAh). Wanted to test the actual capacity of these and put them into my charger to test. I also tested examples of my existing low discharge NiMh cells for a comparison. Have put the results in a table for you. The 2 AA’s were around 2400 mAh which was about 12 – 13% below the 2800 mAh claimed. So these cells have come out lower than their stated capacities, while the other cells I have had broadly outperformed their stated values. On the surface, this may seem that these cells have overegged their values but you need to bear in mind that this was the first time I had used these cells and their capacitates may get better over time (The other cells tested have been through quite a few charge/discharge cycles). On another note, I have only tested 2 Bonai AA’s and 3 AAA’s plus one of each of the other brands. This is not a comprehensive test in any way shape or form but I would still say that it gives us a relatively good idea of their performances. In my opinion, even if these figures are indeed the true values of these cells, I don’t think it should put you off because if you take into account value for money, these are still really good. With regards to discharge rate, I won’t be able to know until I use these for a few months. I would give these 4 out of 5 because of the shortfall from the stated capacity but they still represent great value and I would recommend to you.

Very good

Very pleased with these rechargeable batteries. I use them in my little radio. They last quite a long time.

Great product and everything is in perfect order.

So far looks good. Just charged them and will put them to use for the Christmas decorations. Emailed for a 2 year warranty, which was confirmed within days. So far so good.

I have added one star because following my review they contacted me to apologise and offer a full refund, with no strings. I will not be accepting the refund, because, even though I have not been asked to, I would feel compelled to change my review if I took the refund. I purchased both AA and AAA Bonai rechargable batteries thinking that as suposed to be 2800mAh they would be great. How wrong can you be. I am still using them but they do not last nearly as long as the much lower mAh rated Amazon basic batteries and do not perform anywhere near as well as the again lower mAh rated Enloop batteries. I do not have the equipment to accurately test these batteries but in real world performance for a blood pressure monitoring device, Amazon basics last just over two weeks, of inflating the cuff twice a day, Enloop nearly three weeks and the Bonai three days. I have used both a Nitecore intellicharger and an Xtra smart charger it made no difference and in remote controls the Bonai last a month at best, before the need to recharge the other batteries last well over six months before I charge them, not that the Amazon and Enloop are actually depleted at this point. I would not waste my money on Bonai rechargeable batteries again

This is the third time I have purchased any of these rechargeable batteries and I am completely satisfied with both their performance and their very fast charging. I recommend them.

Estoy muy contento con las pilas recargables BONAI AA de 2800mAh. Las compré hace unas semanas para usarlas en varios dispositivos que requieren pilas, como el control remoto, juguetes y mi ratón inalámbrico, y la verdad es que me han sorprendido mucho. La capacidad de 2800mAh es bastante alta, lo que significa que duran mucho más que las pilas tradicionales. Las he cargado varias veces y siguen funcionando igual de bien. Lo que más me gusta de estas pilas es que son recargables y tienen una vida útil de 1200 ciclos, lo que significa que no tengo que estar comprando pilas desechables todo el tiempo. Esto no solo es más económico, sino también mucho mejor para el medio ambiente. La carga es bastante rápida, y las pilas mantienen su energía durante mucho tiempo, lo que es ideal para los dispositivos que uso a diario. Además, las pilas son de muy buena calidad, se ven y se sienten robustas. No he tenido ningún problema con ellas, ni de fugas ni de falta de potencia. Las he usado en diferentes aparatos y siempre han funcionado de forma fiable. También me gusta que vengan en un paquete de varias unidades, por lo que tengo pilas suficientes para varios dispositivos. En resumen, estas pilas recargables BONAI son una excelente opción para quienes buscamos una alternativa económica y ecológica a las pilas desechables. Están bien hechas, funcionan muy bien y me han solucionado muchos problemas de tener que estar comprando pilas nuevas todo el tiempo. Definitivamente las recomiendo a cualquiera que busque unas pilas duraderas y de buena calidad.

piles rechargeable 1,2 V 2800mAh bonne puissance

Had al een aantal batterijen van dit merk, zowel AA als AAA. Heb er 16 bij besteld omdat ik van AA er wat tekort kwam. Prima kwaliteit voor een goede prijs. Zeker aan te raden om ze te kopen.

Ich habe die AA-Akkus der Marke Bonai, um sie in meinem Batteriegriff für meine DSLR-Kamera zu verwenden, und bin absolut begeistert! Die Akkus bieten eine exzellente Leistung und sind perfekt für den anspruchsvollen Einsatz geeignet. Selbst bei längeren Fotosessions, bei denen die Kamera viel Energie benötigt, haben die Akkus durchgehalten und mich nicht im Stich gelassen. Die hohe Kapazität sorgt dafür, dass ich länger fotografieren kann, ohne ständig Ersatzbatterien bereithalten zu müssen. Ein weiterer Pluspunkt ist die gleichmäßige Stromabgabe. Dadurch bleibt die Kamera auch bei Serienaufnahmen oder bei der Nutzung des Blitzes zuverlässig und stabil. Außerdem konnte ich keinerlei Überhitzung oder Leistungsabfall feststellen, selbst nach mehrmaligem intensiven Einsatz. Die Akkus wurden schnell und unkompliziert aufgeladen, und die Langlebigkeit scheint nach mehreren Ladezyklen ebenfalls hervorragend zu sein. Es ist beruhigend zu wissen, dass ich ein zuverlässiges Produkt habe, das mich auch in anspruchsvollen Situationen unterstützt. Fazit: Die Bonai AA-Akkus mit 2.800 mAh sind eine klare Empfehlung für alle, die auf der Suche nach leistungsstarken und langlebigen Akkus für ihre DSLR oder andere stromintensive Geräte sind. Das Preis-Leistungs-Verhältnis stimmt absolut, und ich werde sie auf jeden Fall wieder kaufen!
