Hi [NAME] welcome to this free user-to-user Alienware laptop discussion forum.  Alienware 17 R4 notebooks have a power supply protection circuit integrated within its system board (aka motherboard) which is designed to accommodate OEM replacement battery 68Wh DP/N 44T2R (15.2V) and 99Wh DP/N 9NJM1 (11.4V).   Check beneath the OEM replacement battery white label's square matrix that year/month is less than 6 months old. Reject battery if there is no white label.

Dear Support-Community, the Battery of my 17 R4 has to be changed. I ordered a new Battery from the official Dell-Store. The Store suggested a 68 Wh / 15.2 V Battery for my Service-Tag (There is also no other option). My actual / defect Battery has 99Wh / 11.4 V. Afaik, this big Difference in Voltage (15.2 V to 11.4 V) is normally a high risk for the Notebook. So my question is: Is it safe to replace the defect Battery with the new higher voltage one? Thanks in Advance
17 R4, battery replacement, higher voltage one?
