got the battery from seller "Ascoon" as new.
Have bought a new, as my old (bei Freddy und Jürgen) battery has survived no more day. Since I had read in other batteries in the recessions that Qualtiät is suboptimal, I was blinded in this by the recessions. The battery lasts barely one more day through, is very hot and is worse than the originals battery (which I have unfortunately already discarded) after barely 2 months.
As my grandfather used to say: "We have so much money that we can buy cheap?" That seems to be coming true in this case again, as I once again must fetch a me. :-(
