Only batteries provided a charging fault in the 1st charging, which explains the star less in my rating. I had to make a particular manipulation, happily under my battery charger, which allows a "refresh" of faiblichonnes batteries by several charge cycles and successive discharge. I have no problem since, but for someone like me that does not have a charger worthy of the name, to finely control the level of battery charge, it can pass for a defective battery ...
In short, I will gradually replace all my rechargeable batteries "classic" by these equivalents "preloaded" (the next to be eligible will be my flash cobra).
