Magic, Far better than the older rechargable batteries. Bought Dec 24.
My old NiCad batteries are failing, yes more expensive but last a lot longer without recharging. Money Money It's a poor mans world. Wife buys boxes of batteries, LOL. Some items do not like NiCad batteries, tried them in these items & Magic, Test meter I use all the time, never had to recharge so far after a year. I will be buying more LI batteries, including for my home made solar system. Well there appears to be problems with 3 batteries, 1 in mouse & suddenly died, then tried another & nothing, tried charhing a spare & will not charge. Having read about other makes, there appears to be problems, wonder if they are using the same manufacturer? Even EBL & others, have had faults, batteries burning, not charging, ETC. EBL recommended using a USB charger which worked. On top of this suspect my "Family have been using my batteries & not knowing they are rechargeable bin them. So will be putting the rechargeable batteries in a secure place in future. Will update later.

Avoid, worthless rubbish.
They look good, with a nice charger, but as for reliability they're useless, charged them up and went totally flat in a week without being used, not what li-ion batteries should do.

Great rechargeable batteries
These batteries are a step up from conventional rechargeables. Once recharged, using a special USB powered device, they hold their rated 1.5 volts until they become fully discharged after supplying an amazing 1100 milliamp-hour! Excellent AAA batteries for almost any application.

Brilliant when they work !!
They give a good output when charged - 1.57 v as measured by a battery tester. However, their quality control process is bad - about 1/4 of them are not recharging after two charges (maximum). Very few rechargeables have a 1.5 V output, so I would use them when this is essential. However, I would try another brand to see if they have more reliability.

Needs special charger
Doesn’t fit normal chargers

Nice Lithium batteries but rubbish charger
The batteries seem good enough with fairly high 1100 mWh rating so should last a while. Bit gimmicky flashing led's during charging but fun to watch. However, the charger is not good. Luckily I purchased two sets of batteries with chargers because one of the chargers that came has a faulty slot and will not charge. The red/green slot led doesn't light up where the other three do, the battery flashes for a few seconds and stops charging. Swap it to another slot and it charges fine. Bit disappointed but I do have another charger from Kratax so all is not lost. Can't recommend for this reason.

Numero 4 batterie Mini stilo al Litio Ricaricabili prese a un prezzo corretto tra le pochissime trovate su Amazon che vengono ricaricate tramite apposito caricatore per batterie al Litio, se ne trovano parecchie con cavo USB per carica diretta mentre avendo già un caricabatterie per batterie al Litio mi servivano queste. Qualità/prezzo Ottima

Es la tercera vez que compro pilas de litio de esta marca, tengo unas AA y van bien . Necesitaba otras de repuesto para el NUKI del portal, ya que duran más que la de níquel y solo disponía de las cuatro en funcionamiento, son AAA. También las voy a usar para un espumador de dos pilas AAA. He probado con las de NiMH recargables pero al ser dos y pequeñas no tienen mucha potencia al espumar nata. Ya las he puesto y el espumador va mucho más potente, y durará más tiempo y al cien por ciento hasta agotarse. Estoy cambiando las pilas recargables de NiMH por estas de níquel, poco a poco ya que son bastante caras. Pero para aumentar la potencia van bien. Saludos.

Damit der Ladevorgang erfolgreich startet, sollte man/musste ich wie folgt vorgehen: 1. Ladegerät mittels USB Kabel anschließen (grüne LED leuchtet) 2. Eine Batterie nach der anderen Einlegen. Das Ladevorgang sollte dann erst Starten bevor man die nächste einlegt. Das erkennt man daran, dass die LED über dem jeweiligen Steckplatz anfängt zu lechten und der Batteriepol fängt an zu blinken (sehr interessant) Was nicht funktioniert: Alle Batterie zunächst einlegen und dann das Ladegerät anschließen. Die Batterien werden so nicht geladen! Vielleicht steht das auch im Handbuch, dass ich direkt nach dem Auspacken weggeworfen habe. Ich habe wirklich nicht damit gerechnet, dass ich es lesen muss (wenn es überhaupt drinsteht).

Gute Akku mit 1,5 V ruckzuck aufgeladen und hält lange.
