A:Answer I finally found more detailed specs & build info, @ Dell support site. Using the device Service Tag, or Express Service Code (from an in store display unit).
http://www.dell.com/support/home/us/en/19/product-support/servicetag/HDMDQF2/
Dell Service Tag - HDMDQF2.
Express Service Code - 37828952318.
This is the same model.
Battery Dell 40Wh (14.8Vdc/2750mAHr). Externally removable (quick release).
(Tip to find info about Dell computers is to not include the 1st letter(s) in the model number/ID. Could not find on Dell site until I left out initial letter; Dell support specs dues not include the 1st letter either.
Example, this is Dell Inspiron I5566-3000BLK-PUS. Don't include the I in I5566, just search by 5566.
In this case, I think I in I5566 is abbreviation for series name, Inspiron.

Also, for Dell, search by Service Tag, or Express Service Code may work, if normal model, or UPC/EAN/GTIN code search does not find.)
