Hi sorry to tag onto an old thread but....my daughter has just picked up a Pendleton from Halfords, we have the same issue as first poster the manual has a different battery pictured, we cant work out which way is open for the key and dont want to force battery out. I appreciate there is a knack ( have two other ebikes) but can find any "give" in it at all and dont want to break the mechanism. would anyone have a picture ( or clear explanation) of their key in the open position please, just so we know we are turning the thing the right way?? Many thanks
