Caution merchandise is defective

Think that these batteries already were ok if they were loaded. My heart rate monitor from Polar indicates a poor state of charge and after about 2 days without use, it is also out again. Now I have put a Duracell from Conrad purely and behold the display of the battery is full.

I also have a battery meter and also indicates an almost empty state. In the Duracell out of the store, however, the display on the attack is full.

Conclusion: Test prefer before you can change this to one another by and then all throw away the batteries supplied.
