Short version:This charger gently charges and discharges my aa batteries with a display to follow progress.Long version:Nerd alert!!🤓As I use my AA batteries in a series pack of 6 to achieve an average of 7.2v, I am not able to periodically run the batteries down completely as a pack (as recommended by some sources) to the 0.9v for each cell because there is a danger of reverse charging one or more of the weaker cells which will damage them. So on removing my batteries from their pack, this charger allows me to run each cell down individually to 0.9v using the discharge function to remove what they call the "lazy effect" or "voltage depletion" which according to some, adversely affects battery performance. Once discharged to 0.9v the batteries can then be fully charged. The charging time for my 2500mah batteries (assuming this is their true capacity) in this charger from empty is about 7.5 hrs or overnight. The illuminated screen, which is a nice feature, shows each battery's charge status and voltage as you use left or right buttons to scroll through each channel. The screen also tells you if you are charging, discharging or refreshing. The refresh function appears to be a charge, discharge and recharge all in one program. Even if the 4 batteries are at different states of charge during the refresh program, this charger will individually take each battery through the refresh program. So some may be charging and others discharging at the same time. The batteries and charger at no stage get hot, which indicates a nice gentle charge which is good for battery life (I cannot confirm the claim of 500ma charging and discharging). The batteries are slightly warm when charging and increase in temp as they become fully charged but never get hot. Discharge of my full 2500mah batteries takes about 8.5 hrs. I'm hoping this charger stands the test of time because at the moment it is doing everything I need it to, and as this is my first foray into intelligent charging, it is quite satisfying to be able to monitor battery status as it charges and discharges. This charger doesn't record the capacity of each battery in mah during the refresh program though, like some chargers, but this is an acceptable compromise at this price point. So not a high speed aggressive charger, but a gentle charger, that will care for your batteries.P.S. - A nimh rechargeable battery can show 1.2v when it is empty and not under load. As soon as you load it the voltage can drop to 0.9v or lower.

Dicono che le pile NI-MH non hanno effetto memoria ma a me non risulta. Con questo caricabatterie posso scaricare completamente le pile prima di ricaricarle. Inoltre grazie alle indicazioni sul display si capisce quando una pila ricaricabile è esausta e si deve eliminare.Comodo il cavetto di alimentazione e le due prese usb (B e C).Consiglio per chi lo userà: non sono un elettronico ma credo che quando si caricano tutte le quattro pile a 500 ma, il caricabatterie ha bisogno di un alimentatore capace di erogare 2 A almeno anche perché le normali prese usb dei PC non erogano tutta questa corrente.

Troppo poca potenza. Il massimo che carica è 700 mAh. Soldi buttati

Das Ladegerät ist vielseitig einsetzbar, da es ein fest verbautes USB-A-Kabel und zusätzlich eine USB-C sowie eine Mikro-USB-Buchse enthält. Mir gefällt das Design sehr gut, es sieht aus wie ein Sportwagen, dessen Vorderseite dem Benutzer zugewandt ist, in der Mitte das LCD-Display in Form einer Windschutzscheibe, links und rechts die beiden Tasten in Form der Scheinwerfer , diese sind allerdings nicht beschriftet. Drückt man eine der beiden Tasten kurz, schaltet man zwischen den einzelnen Baterien hin und her und kann sich die aktuellen Volt anzeigen lassen, mit denen geladen bzw. entladen wird. Drückt man den linken Knopf etwa eine Sekunde, wechselt man zu "discharge", bei erneutem Drücken für 1 Sek zu "refresh". drückt man den rechten Knopf eine Sekunde, wechselt man von 500 Milliamperestunden zu 300 MAH bzw. bei erneutem Drücken wieder zu 500 MAH, dies gilt für alle 3 Modi "laden, entladen, auffrischen). Das Ladegerät ist sehr stabil verarbeitet, der Druckpunkt der Knöpfe ist deutlich spürbar und löst zuverlässig aus. Einziger negativer Punkt ist, dass es nach erfolgter Entladung nur "Discharge End" anzeigt, jedoch nicht automatisch in den Lademodus wechselt, dies muss man manuell durch zweimaliges einsekündiges Drücken auf den linken Scheinwerfer durchführen. Überdies erreicht es zumindest beim Laden kaum 500 MAh, meiner Einschätzung nach eher 300, was andere Rezensenten vor mir schon bemerkt haben.Alles in Allem gibts von mir eine klare Kaufempfehlung angesichts des Funktionsumfanges und der hohen Stabilität des Gerätes!

Frente al que tenía anteriormente con un adaptador de corriente propio y una pieza móvil para cambiar entre AA y AAA., la alimentacción por cable USB y el poder cargargar las pilas una por una y de distintos tamaños le da una versatilidad tremenda. Ideal para viajes. Además el display da una idea de la cantidad de carga (el otro que tenía sólo encendía un led verde al 100% ) y puedes decidir si las cojes a medio cargar o esperas. MUY BUENA COMPRA.
