Great battery with convenient charging!
I bought these for my Mixer Reality VR handsets, they eat batteries and even with light use, I would have to change them after a couple of sessions!So far I've had them for a few months and they really last! I have charged them once, but due to the lockdown, i was using the VR maybe 10x more than normal! So for my application, they are great!I also really liked the way the batteries charge, as they do not need an external charger, you can just plug a standard Micro USB into them and charge them form any USB charger!They are not cheap, but for me, i'd prefer to have something that lasts and that's rechargeable, as I felt a little guilty with the amount of batteries I was throwing away, before!I can't say how long thee will last long term, so if the fail, I will update the review, so people know!For now they're great!!

Work well in a setup with normally a very low drain condition but with occasional high drain demand
Have fitted these into two Netatmo Thermostats that were chewing Alkaline batteries for no perceivable reason. They have been working now for two weeks without heat demand, so in a very low current drain condition that just keeps the WiFi connection up and the LCD working. There is no sign of reported battery voltage falling on the Thermostat valve App information even having carried out numerous high current drain valve calibrations. Ok, they are far more expensive than NiMH but for applications like the Netatmo valves which need 1.5V and that just won't operate at 1.2V, they are worth that additional cost. So far, very pleased with them and will definitely buy more for the rest of my Netatmo valves.

Can anything be done about the one battery of four that is not functioning.
One the four batteries is not functioning. It will not hold a charge. The other three are fine and do work well. Not quite sure what further action to take. I may be buying another set soon anyway. My ratings above refer to the three working batteries only.

A great kit
Nice kit with wire harness to charge the batteries, also powered an old Nissin flash perfectly

One of four stopped working
A little bit more than 8 months later one of the four batteries just stopped working. It shows that it is fully charged but does not hold any charge. Pretty disappointed, I thought the capacity will downgrade after a while but did not expect it to stop working from one day to another...

Work like a charm
Been great for powering the Rockit baby rocker for our daughter for the last couple of months.Was a bit worried as motors are high load, but they work a charm.If I could I might take off 1/2 a star as the 4-way charger doesn't always seem to get a great connection, but not enough to be a big problem.Now to buy some AAAs for her favourite toy :-)

Costano, ma erogano la tensione nominale (1,5V) fino a fine carica
Prese a marzo 2020, giusto per provare questa soluzione innovativa, queste pile ricaricabili sono decisamente sorprendenti.1° caricate tutte e quattro appena prese stanno dimostrando di mantenere la carica per molto tempo.2° si caricano in poco tempo3° a differenza delle pile Ni-MH o Ni-Cd queste mantengono la tensione nominale fino a fine caricaInserendole quindi in dispositivi dove con le ricaricabili tradizionali si era abituati a vedere apparire l'indicazione di batteria in esaurimento sin da subito; con queste questo non succede mai.Di contro possono lasciarti "a piedi" improvvisamente proprio per questa loro particolarità, ma è un rischio che posso correre.Sono ancora decisamente costose, ma con l'andare del tempo il prezzo di mercato dovrebbe scendere progressivamente.

Hoffentlich (auch langfristig) eine gute Wahl
Wir hatten Akkus unterschiedlichster Hersteller und unterschiedlichster Preise. Die Standardakkus in deutschen Geschäften bringen aber keine 1,5 Volt. Und so quälten wir das Internet und wurden hier fündig. Zwar deutlich teurer, als die in deutschen Billigläden anzutreffenden Akkus, aber halt mit echten 1,5 Volt!!! Und Ladung mittels (da könnte man noch besser werden) proprietärer USB-Ladung. Die Langlebigkeit erhoffen wir uns noch, weil die "ältesten" jetzt gerade einmal ein Jahr alt sind. Aber Ladung geht superschnell und einfach und die erbrachte Leistung übertrifft alles bislang dagewesene. Wir hoffen auf mehr Ladezyklen, wie bei den bisherigen Pseudo-Akkus auch deutscher Markenhersteller, die ihr Geld allesamt nicht wert sind.

Van muy bien
Funcionan perfectamente, llevan todo lo necesario.Es difícil saber si la durabilidad es adecuada porque todo depende del uso que se le de …

Ricaricabili assolutamente consigliate (queste e anche le nere)
Ottime ricaricabili, sia queste che quelle nere. Acquistati diversi set per usarle in fototrappole. Longeve, anche in inverno. In uso da oltre un anno. Una singola batteria era difettosa, non era possibile ricaricarla. Il venditore Blackube, contattato al riguardo, ha mandato gratis un intero set di 4. - Non capisco perché nella valutazione Amazon chieda cosa si pensi del "controllo remoto". Quale controllo remoto, di grazia? Sono BATTERIE. Accumulatori di energia. Cosa vuoi controllare da remoto?

Blackube AKKU 1,5V 1700mA
Habe inzwischen 8 Akkus im Gebrauch ,eine tolle Idee der Entwickler ,ständig 1,5 V stabil liegen an,übertrifft normale Batterien um einiges ,bequemes aufladen der Akkus,Wenn Ladung verbraucht ist sofort Schluß ,keine Anzeichen ( bei Kerzenbetrieb) das die Leuchtkraft abnimmt.Sicher noch etwas teuer , denke mal das ich gute Qualität gekauft habe,
