It has arrived. Extremely happy with it. It was packaged very well, maybe too well. Other than that, inserted it into the laptop (K52JT) and it's working very well.
Product received 3 weeks after orderdate. Sufficiently packed and protected against damage and against Electrostatic Discharge (ESD): ESD plastic bag was used, GOOD JOB! Also a munual has been included giving directions for a better lifetime of the battery. Laptop indicates 48.4 Wh capacity, 11.9 Volt, meaning around 4070 mAh which is somewhat less then the 4400 mAh ordered. Anyway good for around 1.5 hours of use. See the pictures as evidence of above information.
