Also with me the battery did not fit for the Medion E-6228th I thought that the problem is resolved according to the reviews, but obviously it behaves so that Medion has the E-6228 manufactured in two construction types. Therefore, my theory: E-number and MD number must match the device. For me, however, only the E-number agreed not MD number on the laptop with the information. Therefore: bad buy. Return, however, was without its problems.
