This is a brand new Sony replacement battery.
Estimated run time with this battery is 2-3 hours. Longer run times can be achieved by minimizing the power use, especially the screen brightness.
The superior cells inside the battery cartridge will provide longer run times between charges as well as a longer service life than cheaper batteries. In addition, Li-ion batteries are not subject to the memory effect common with older battery technology. This means you can recharge your laptop any time without diminishing your battery capacity. The battery is individually tested before shipment and backed by 30 day complete satisfaction guarantee and a 2 Year warranty.
The battery is designed to fit perfectly into your laptop and includes rubber feet which will rest on your table surface.
Not all computer batteries have the same capacity and run times. The higher capacity battery cells inside this cartridge have an energy capacity of 5200 mAh. These are the highest capacity Li-ion batteries on the market today and superior to batteries rated at 4400 & 4800 mAh. This battery will deliver 20% more run time than cheaper 9 cell versions and 77% more run time than cheaper 6 cell versions of this battery.
This battery replaces the Sony Vaio Z500, Z600, Z700, Z800, VPCZ110, Z11x, Z12x series laptop batteries and additional machines which are listed at the extreme bottom of this web page.
