Welcome to a laptop battery specialist of the dell laptop battery
The Inspiron 13z is equipped with the same ultra-low voltage 1.7GHz Intel Core i5-3317U processor seen in both the Lenovo IdeaPad U310 and the HP Envy 4-1043cl, paired with 6GB of RAM. Scoring 2,457 points in PCMark 7, the Inspiron pulled ahead of the ultraportable Editors' Choice Toshiba Portege R835-P88 (2,313 points), but fell behind both the Lenovo U310 (3,570) and the HP Envy 4-1043cl (3,962) despite the fact that all but the Toshiba are using the same model processor. Thanks to their common hardware, CineBench scores were nearly identical between the Inspiron 13z (2.39 points), the HP Envy 4 (2.38) and the Lenovo U310 (2.39), as were scores in Handbrake and Photoshop. For light video and photo editing, the Dell Inspiron 13z provides decent performance.
Because the Inspiron 13z relies on Intel's integrated graphics processing, most gaming is off the table. Though the Inspiron 13z did score 5,721 points and 3,164 points in 3D Mark 2006 (at 1,024-by-768 and 1,366-by-768 resolution, respectively), the thin laptop only produced 20 frames per second in Crysis at medium resolution, and was unable to run it at higher resolution, or run Lost Planet 2 at all.
While we were unable to run our usual battery such as dell T118C battery , Dell Vostro 1720 Battery , Dell Vostro 1710 Battery , Dell 312-0740 Battery , Dell 312-0894 Battery , Dell 451-10612 Battery , Dell T117C Battery , Dell T118C Battery , Dell P721C Battery , Dell P726C Battery , Dell CMP3D Battery , Dell Inspiron Mini 1012 Battery -life benchmark test, MobileMark 2007, we did perform a video rundown test. With video being played continuously, the Dell Inspiron 13z's 49Wh battery lasted 5 hours and 5 minutes. We can't make a direct comparison to the results of our MobileMark test run on other systems, but with most scores ranging from 6 to 10 hours, it is safe to say that the Inspiron 13z will get you through most of a day, but not all of it.
The Dell Inspiron 13z is an affordable and able ultraportable, but some users will be irritated by the port covers that get in the way more often than not. The hardware puts it alongside some fine ultrabooks and ultraportables, but unlike the Editors' Choice Toshiba Portege R835-P88, which also offers extras like WiDi and an optical drive, the Inspiron 13z falls just a bit short of expectations.
