Welcome to a laptop battery specialist of the dell laptop battery
Despite the squeaking space bar and a cursor that sometimes skipped all over the screen as we typed, the Zenbook Prime offers a much better overall user experience than its predecessor. It's comfortable for lap use, its keyboard is enjoyable to type on and, above all, it's screen is simply beautiful to look at, whether you're working on documents, editing photos or watching movies.
A 50 Watt-hour battery like dell Inspiron 1525 battery , dell Inspiron 1526 battery , Dell HP297 battery , dell GW240 battery , dell RN873 battery , dell XR693 battery , dell 0XR693 battery , dell 312-0625 battery , Dell Latitude X200 battery , Dell 8U443 battery , Dell Latitude X200 battery , Dell 312-0058 battery is installed in the chassis and it provides the Zenbook Prime with a very useful lifespan while it's away from an outlet. In our standardised rundown test, in which we disable power management, enable Wi-Fi, maximise screen brightness and loop an Xvid-encoded video, the battery lasted 3hr 29min. This is a little lower than other Ultrabooks, such as the Samsung Series 9 and even larger Ultrabooks such as the Dell XPS 14, but considering the high-quality, Full HD screen that the battery has to drive, we feel that it's a respectable result.
While using the Zenbook Prime for everyday tasks such as word processing, Web browsing, watching the odd YouTube video and listening to music now and then, it lasted close to five and half hours, which is a great result. That was with the screen brightness at the halfway point, the keyboard backlight enabled at its lowest intensity, and with the system at the high performance power setting.
With solid construction, a superb, Full HD screen, a backlit keyboard, fast performance and good battery life, the Zenbook Prime is a strong candidate for Ultrabook of the year. It does have some niggling problems, such as a touchpad that can sometimes make typing difficult, an ambient light sensor that isn't overly sensitive, as well as a squeaking space bar (on our test model at least), but overall it's a very good unit that's worthy of your consideration. Official pricing that we were given for this unit at the time of publication was $1799 $2199. Online searches turned up pricing that was closer to $2000, so it pays to shop around. The Core i5 version with a 128GB SSD costs closer to $1600.
