Accu could be difficult to remove from the charger because bevels on housing were a bit too small. After some reworking They adapted very well. The capacity is very good. The headset BA 151 went out after about 3.5 hours. With the second battery, this means about 7 hours of television or listening to music at a time. Delivery arrived only 10 days after the alleged Absendetermin. Strange that the post so long needed in Germany for delivery. The remark that the seller has seen the TV report that the Post has used for a postcard 31 years, leaves an unpleasant aftertaste.
