Best batteries. Great charger too.


from U.S.A.  -  Quality Oriented

Bought this product for use with my Xbox One controller/other high drain devices and they last a very long time. The charger works exceptionally well not just at this price point but at any price point. The charger charges each battery individually which optimizes the performance of each battery unlike the cheapy chargers you get with Energizer/Duracell which charge two baterries at a time so one battery will always get overcharged. The Panasonic charger also has a light indicator for each battery which let's you know if its charging or if its done. When it is done charging the charger will cut the charge off or at most leave a trickle charge as to not ruin the batteries by overloading them. I fully charged the batteries. Put them back in to charge and within a couple minutes the charger cut power and the battery cooled down which indicates the charger isn't loading them. Duracell and energizer chargers will keep loading the battery and they get hot which degrades the battery faster. Charges at 300mA which is good for the battery because it will charge each cell to the fullest and not overheat the batteries unlike those fast chargers. Also its not too low of a charge because if it's too low,say 200mA the charger can't detect when the battery is at capacity and it will keep charging it. Some might think that the charger is too slow but why complain when you can have a few sets charged and ready to go. One last thing. Don't bother buying those expensive Maha or Lacrosse chargers. Those were good for old technology NiCd batteries which had memory issues and needed to be conditioned every once in a while. These Eneloops NiMH batteries don't have memory despite what people say. Sanyo/Panasonic is a trusted company and they state these batteries don't suffer from memory. So again don't bother with expensive chargers. The Panasonic BQ-CC17 charger that it comes with is all you'll ever need.
