I have only charged these once and installed 2 in a blink doorbell. As the title says,nthey are slightly smaller than standard and seem quite loose in the bell. I actually had to bend the terminals in the bell to make the batteries fit better. They seem to hold their charge but time will tell.

AA rechargeable LITHIUM batteries charger (will only work with LITHIUM batteries) that can provide 2500mWh of charge to devices inserted into at 1.5v and a lifespan of 1600 + rechargeable cycles (phenomenal) The charger has absolutely has to be the smallest and thinnest charger I have ever used or owned! Charging speed is exceptional also and the charger has a simple coloured light to show status of charge or when fully charged. This order also comes with an amazing 8 x AA batteries at an excellent price and true value for money. My only drawback is this will only charge AA batteries and not work to charge AAA batteries, but I knew this before ordering and still happy to have gotten these and their overall usage and battery life. Each battery can be recharged over 1600 times and each battery also includes protection smart chip technology via the SmartProtect Chip for the below to ensure safe usage and charging. Overcurrent Overvoltage Overcharge Over-Discharge Short Circuit Temperature (while charging and in use) Anti-Leakage I have been using these now for several weeks in my mouse, keyboard, game controllers and superbly happy with the longevity of usage and keeping charged up. On the details page for this charger and batteries it states 90 days for a remote control, 35 hours of usage on a game controller, 30 days for keyboards and 47 days for a mouse. To be honest in my daily keyboard and mouse I have been using these in them for the last 25 plus days and they are still over 30 charged. If you are looking to move to rechargeable batteries for AA then an excellent reason to purchase this charger and AA batteries.

I feel the item should have a further connection so can plug into mains without buying a further connection

I am totally non technical so most of the reviews I have read are full of information I do not understand. All I want to know is does it work, is it easy to use and is it safe? My first observation was I received 4 batteries and not 8 like some reviewers and that the charger itself was much smaller than I was expecting. When I connected the charger to the power supply via a USB plug (not supplied but available on Amazon £5.45) little green lights by each of the 4 batteries started flashing. After just over an hour the green lights were continuous which I presumed meant they were fully charged. I have used the batteries in a number of items and I cannot find any performance difference compared with traditional batteries. I haven't yet assessed if they last as long. On the safety front the charger didn't overheat and I have not read of any problems experienced by other reviewers.

Customer Review
I'm really impressed with this set of rechargeable AA batteries and the included charger. It feels like a very modern and convenient system. What I particularly love is the charger itself. It's incredibly slim, making it easy to store or take with you if needed, and it uses a standard USB-C connector for power, which is much more convenient than proprietary plugs or older USB types. It also charges the batteries fairly quickly – I found it takes roughly two hours to fully charge all four, which lines up with the fast charging claims. The batteries themselves are the LiFePO4 type, which deliver a constant 1.5V output, useful for devices that might be fussy with the lower voltage of standard NiMH rechargeables. I've been using them regularly for a while now, probably putting them through about 15 charge cycles, and they are still going strong with no noticeable drop in performance. Overall, I think this is a fantastic rechargeable battery solution. The combination of fast charging, the practical slimline USB-C charger, and the reliable performance of the batteries so far makes this an excellent choice for replacing disposable AAs. Highly recommended.

Très bonne surprise avec ces piles rechargeables lithium AA imuto ! Elles arrivent bien emballées avec leur propre chargeur, ce qui est déjà un excellent point. La recharge est rapide et les témoins LED du chargeur sont pratiques pour suivre l’état de chaque pile. Ce que j’ai particulièrement apprécié, c’est la tension constante à 1,5 V : ces piles gardent la même performance jusqu’à la fin, ce qui est vraiment utile pour les appareils sensibles comme les jouets électroniques, les manettes ou les lampes LED. L’autonomie est aussi impressionnante. En plus, elles sont données pour 1600 cycles, donc un excellent investissement sur le long terme. Très peu d’autodécharge entre deux utilisations, ce qui est appréciable si on ne les utilise pas tous les jours. En résumé, un achat utile, fiable et économique dans le temps.

I made the decision in 2025, the very brave decision, to get rid of all my old rechargeable batteries and replace them all with rechargeable lithium batteries. Because I deserve it. My Xbox controller deserves it My Canon 600 EX – RT/deserves it. That flashlight that only half works, but you refuse to throw it away, deserves it. All my old rechargeable batteries, the ones that don't have as much capacity or provide a pure 1.5 volts, I can't even look at them anymore. They disgust me. What was I even thinking when I bought those? Oh yeah that's right. There wasn't lithium rechargeable batteries back then. I gotta get myself a break with these things, calm down a little, go with the flow.

Die Prime- Lieferung erfolgte innerhalb eines Tages. Die Akkus und das mitgelieferte Ladegerät machen äußerlich einen soliden Eindruck. Die Ausgangsspannung der Akkus beträgt unter Last 1,53-1,59V, wobei die Spannung bis kurz vor "leer" konstant bleibt und fällt dann bis zum Abschalten sehr schnell bis 1,1V ab. (Step- Down- Regler für die Lithiumzelle 3,7V---->1,5V) Die Kapazität wird mit 2500mWh angegeben, was bei 1,5V 1666 mAh entspricht. Meine Kapazitätsmessung ergab nach dem ersten Lade- Entladezyklus im Schnitt 1700 mAh +/- 50mAh. Das entspricht ziemlich genau der angegebenen Kapazität. Gemessen wurde die Entladung mit einem Profi- Ladegerät bei einem Entlade- Strom von ca. 500 mA. Damit heben diese Akkus sich wohltuend von Produkten aus einschlägigen China- Verkaufsportalen ab, wo sehr oft Fantasieangaben aufgedruckt sind. Der Ladevorgang muss mit dem im Lieferumfang enthaltenen Ladegerät erfolgen. Bei mir funktionierte damit auch das Laden von 1,5V Lithium-Akkus anderer Hersteller. Ich probiere diese Akkus im Moment in Fritz!DECT 301 Thermostatreglern und werde beobachten, ob der schnelle Spannungsabfall am Ende der Kapazität praktikabel ist. Zusammenfassend stelle ich fest, dass das Angebot ein sehr gutes Preis/Leistungsverhältnis besitzt. Über die Haltbarkeit kann ich noch nichts aussagen.

Es una batería que entrega 1.5V hasta el ultimo momento, es decir, no como otras que conforme van perdiendo carga también cae la tensión o diferencia de potencial por tanto entrega el 100% de su energía y cuando se agota la carga corta la tensión pasando del 100 % a 0% mas o menos lo que quiero decir con todo esto es que no las vereis venir que estan proximas a agotar la carga lo digo por que en caso de linternas las encendereis y dara la luz al 100% y a los 30 segundo so podeis quedar sin luz porque no las vereis agotarse poco poco por lo demas son perfectas.
