In my eyes the last dirt shop, there was no answer to any of my emails. Never again a bicycle battery from BMZ, customer friendliness looks different.
Well, then I have to buy a new battery and according to my dealer it is not available !!
More questions about this "bomb company"?
Unfortunately, you have to give it a star, you don't deserve it.
Update: I've been waiting for a new battery for three weeks now !!!!
ok, now almost 7 weeks
