Since I was able to Braun shaver only 3-4 days with the old battery use, I bought the batteries from Sanyo Eneloop. Built and now I can shave 3-4 weeks with the razor me again. Note: The solder tails are no standardized solder tabs that you immediately plugged into the Lötlöcher the board and can solder. Here you have a wire cutter solder tails are cut to fit (at my Braun shaver). But there is no point deduction, because it ensures applications for batteries are where these solder tails are also used as.
