17 R4, battery replacement, higher voltage one?

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
