The removable 36Wh battery in my Venue 11 Pro has physically swollen to the point where the back tabs on the removable cover are not staying connected as intended.  There are always 2 or 3 tabs not latching, but I continue to use it.  Is any one else having the same problems?

(I wonder if Dell's selection of their battery manufacturer/provider the same as Samsung's for the Galaxy Note 7?)
