Producto fantástico. No es barato, pero hay mucha diferencia en cuanto a rendimiento comparado con las baterías de NiMh

Es ist inzwischen der zweite Satz Akkus, die ich für meine Wildkamera habe. Der erste (anderer Hersteller und Marke) ist rund 2+1/2 Jahre alt und immernoch im Dauergebrauch. Langsam merkt man das aber an der Leistung.Diese hier sind super praktisch zum aufladen in der Box und gleichzeitig auch eine sicherer Aufbewahrung.Sie funktionieren wie erwartet sehr gut, man merk deutlich das sie neu sind im Vergleich zu den anderen.Was sich auch hier allerdings nicht geändert hat ist das sie bei Minusthemperaturen nich sehr lange durchhalten. Das ist bei dem alten Satz noch mehr zu merken.Unabhännig davon sind diese Akkus wohl immer ihr Geld wert wenn man sie dauerhaft nutzt.Kann sich aber jeder selbst ausrechnen wenn er mal mit Sandartbatterien vergleicht, spätestens nach dem 50sten mal laden, hat man auf jedenfal gespart.Ein kleiner Kritikpunt allerdings für fast ALLE Anbieter von solchen Akkus.Es wird die Leistung inzwischen meist in mWh angegeben, das ist aber etwa das 1,3fache von den mAh die man gewohnt ist. Also gut Aufpassen was man kauft und sich nicht von Großen Zahlen blenden lassen !

Super functionne 100 %

I have a trail camera that uses eight AA alkaline batteries and gets through them at an alarming rate. I can’t use rechargeable NiMH cells as their 1.2V is too low to operate the camera - depleted alkalines still measure 1.4V when they are rejected by the camera. To the rescue, this set of 8 rechargeable AA lithium cells in their own bespoke charger.The lithium cells have several potential advantages in addition to them being reusable hundreds of times. Most significant is the stability of the voltage which should remain at 1.5V until the cells are fully discharged. They don’t follow the discharge curve of alkaline cells where the voltage gradually diminishes - hence my camera rejecting them at the 1.4V point where there is still power left in them. In some applications constant voltage ending in a cliff edge is a disadvantage. It’s sometimes nice to know the battery is running out so you can conserve power. The manufacturer of these cells has an alternative product (available on Amazon) that actually follows the alkaline discharge curve for uses that benefit from the advanced warning it gives. The electronics in the cells has a lot of control over the terminal voltage which is derived from the much higher 3.7V from the lithium cell, enabling them to tailor it to fit whatever is needed.Another factor are the dimensions of the cells. Many Ni-MH rechargables are fatter than alkalines and my camera has tight tubes into which the cells fit. These lithium cells are the same as Amazon Essentials alkaline and slide in without sticking. Another parameter that might be of interest to some uses is the light weight of lithium cells, for a given capacity, compared to other chemistries.Regarding capacity; I carried out a discharge test to find out what it was. Before doing so I fully charged the cells in their bespoke charger. From new they all needed a top up and the charger appeared to work perfectly. All eight green LEDs flashed as the cells were charging and all eight went solid green to show the charging had successfully finished.I connected one of the cells to a discharge tester and drew a current of 500mA from it. The cell shut down after delivering 3.032Ah which, at 1.5V is 4548 mWh. This is well above the 3600mWh printed on the label and is exceptional - it might improve with a few charge/discharge cycles.The cells are now in my trail camera. If they perform well over the next few months my five star rating will be justified - if they don’t I will be back to update this review.
