Don't buy from Ubatteries, they charge you for shipping to and from them if your battery fails, Cost nearly as much as the battery itself. Died after 6 months, they want me to pay for shipping back to replace it under warranty, and then pay for shipping back to me. After complaining about shipping, they will ship back the defective battery, but refuse to ship a new battery. They do not honor their warranty of replacement for a year. Try a different product like I did. http://www.amazon.com/gp/product/B00BM09CLA?psc=1&redirect=true&ref_=oh_aui_search_detailpage Great product and the battery from these guys fits properly, and props up the Laptop so it doesn't overheat.
