Fujitsu HR-3UTCEX(4B) 4-Pack AA 2100 Cycle Ni-MH Pre-Charged Rechargeable Batteries (Made in Japan)

Great batteries, on par with my Enloops. I’d say they are priced well for the quality you get.

Good Fujitsu recharging battery

Spend a little more, get a better product from a known manufacturer. When these batteries are charged, they last a long time. They are sold in different mAh capacities (mine were 1900) so check that before you buy. Higher mAh capacities cost more but last longer between charges. This is not my first purchase of these batteries and I will be buying more.

I order these 4 pack rechargeable batteries. They came right on time when I needed them. Very fast delivery. They're easy to use and rechargeable and value for money. I am highly happy with my purchase!! I would highly recommend this seller and I order more for my daughter.

I've used these for years in many RC and remote control devices. The rechargeable type battery is the way to go, unless you like spending money on batteries. Over a year these are not 1/10th the cost over Alkaline batteries, and will last as long.

Holds up charge. Minus 1 star because it heats up when cahrged at 1C rate.

What attracted me to this particular brand of rechargeable batteries was the fact that they were made in Japan in the same factory that makes Eneloop and Ladda, according to my research. I bought these in June 2024. It looks like they were made in September 2023. They were a little older than I would have preferred, but I thought I would give them a try. Initially, they tested at 1802-1859 mAh, which was quite disappointing because it was below the advertised minimum of 1900 mAh. However, after doing a Discharge/Refresh cycle, the capacity went up to 1960-1973 mAh. This was acceptable to me and I decided to keep them. I will update my review if I encounter any issues in the future.

Estupendas pilas recargables de calidad contrastada. Las compré cuando bajaron a 6€ el pack y desde entonces han fluctuado como siempre sucede en amazon xD Review: Vinieron precargadas. Nada más sacarlas del blister ya se aprecia la calidad a simple vista y más al tacto. Tiene un satinado muy agradable. De peso tienen 25gr, lo normal en este tipo de baterías. No puedo determinar su capacidad real pero el voltaje al que las encontré fue de 1.28. Las cargué a 0.3A durante casi hora y media y ahora están estabilizadas a 1.38 (perfecto). Deduzco que las fabrican en la misma planta que las archiconocidas eneloop. También hay el modelo de 2500mah y los formatos triple A también concuerdan con las capacidades eneloop. El tiempo dirá si mantienen la carga y salen buenas o me ha engañado el delicado tacto satinado. PS: Pronto me agenciaré un buen cargador, y si hay algo nuevo a comentar ya editaré la opinión. Gracias por leerme.

Da quanto ho letto, queste batterie stilo (AA) superano in qualità le eccellenti Panasonic ENELOOP, che compravo da tanti anni. Per adesso, acquistate da più di un mese, ancora non si scaricano: sono abbastanza confidente che la tecnologia "Made in Japan" non deluderà. Tutte le batterie ricaricabili si scaricano anche se non usate, e se le dimenticate nel cassetto troppi mesi la carica va a zero e si danneggiano permanentemente. Queste batterie invece possono stare anche mesi non utilizzate e mantengono sempre una elevatissima carica, con il risultato che non si danneggiano. Consigliate per tutti gli utilizzi, e per un mondo più pulito (senza dover buttare continuamente batterie non ricaricabili).

Excellent product - we got three sets and my charger rated them all at above 1900mAh when tested new (most were over 1950mAh). Of course having only just got them we can't say how reliable they are long term and how well last recharging over time but they're off to a good start :) - will update once we get a bit more use out of them. Update: three of the batteries from one of the packs failed; one after a week and the other two after thirteen months (Amazon, who sold them to us at the time, was kind enough to refund me for the entire pack due to them clearly being advertised as long lasting. The other two packs of four batteries are still working well so I guess it was a duff pack - going to buy a different brand this time though, less than impressed with Fujitsu brand and also customer service - they said it was entirely Amazon's problem when I email to ask about their manufacturers warranty!)

Diese Akkus stehen den Eneloops absolut nichts nach. Sie sind von dem Hersteller FDK (welcher zu Fujitsu gehört) made in Japan und weisen in einem Blister nur eine sehr geringe Streuung auf. Über den angegebenen Mindestwerten liegen alle auch nach unzähliger Benutzung drüber. Was mir besonders positiv aufgefallen ist, dass die Akkus auch bei Kälte gut durchhalten und ihre Kapazität nicht merklich beeinträchtigt ist. Auch beim Ladevorgang mit 1.000mA Ladestrom werden die Akkus nicht sehr warm. Nutze sowohl die weißen, also auch die schwarzen Fujitsu Akkus und spreche für beide Sorten eine absolute Kaufempfehlung aus.
