After 2 months of intensive use of this battery still holds around longer than all worlds "originaakkus" of which I already had tried almost all. Here the price / performance ratio and, above all, the satisfaction of the user. Finally a product be the one no additional cover on the back of still un requires a much greater measure brings. Also have inzwixhen already a 2nd for exchange which holds just as long and scrapped the old "original battery".
