I ordered a rechargeable 550 mAh 2.4V and 2.4V sent me a 700 mAh battery. I'm not satisfied, whatever attempt at explanation or justification according to which a material 700 mAh would last longer, that does not interest me, when I order the 550, I do not want the 700. End of story! The customer is king and must remain so. Auf wieder sehen!
