This is a brand new 9 cell battery for the Dell Studio XPS 13 and XPS M1340 laptop models.
This battery will be physically larger than the original but will still snap into your laptop.
This long run Studio XPS 1340 battery will run at least 50% longer than the standard 6 cell battery that comes standard with your laptop. The added run time is achieved with an additional 3 cells inside the cartridge. This longer running battery will extend to the bottom of your laptop about 1 inch. Users of this battery experience an additional 1-2 hours of run time over the standard battery.
Estimated run time with this battery is 3-5 hours. Longer run times can be achieved by minimizing the power use, especially the screen brightness.
The battery is individually tested before shipment and backed by 30 day complete satisfaction guarantee and a 2 Year warranty.
