Good, but too little information

Like many other customers, and I am constantly confronted with the question: What type of batteries do I buy now? The expensive brand batteries or the respective private label?
The brand batteries I just know that keeping this long. Especially in the wireless mouse and keyboard I need durable batteries. Otherwise brand batteries or own brand have been distinguished from each other little, except of course the price. Therefore, the Amazon variant was worth a test for me.

The packaging size with twenty batteries is a good size and in an emergency you here again in new batteries handy. The batteries are each about ten units - with plastic wrap - packed. The workmanship is good and can compete with other batteries.
My comparison object are a private label batteries. Here the Amazon batteries can definitely compete. In my case, the batteries are so far from the life well. Thus, one of my criteria for batteries is met: Durability. On top of that so far nothing has been discontinued and therefore the first look at the processing has not getrügt.
A deduction there yet, few to no information on the composition of the battery. Since it is difficult to really draw comparisons.
