I can not judge. But the batteries for a long time racked by me and so far they have not failed me even once in the lurch.
Quite different is the normal batteries that I had previously.
I could trade places with the battery usage every few weeks and the empty batery had to be disposed. That hurt not only my purse but had really been almost a guilty conscience towards the environment I had then times no more battery storage in the house my spirits sank equal to the basement because I really am pleased with the battery!
