How many hours of talk when it is fully charged?

Hello, Thank you for contacting us in regards to your question. The best way to confirm specs is actually by checking the manufacturer's website (that's where we get them). Click on the Specifications tab on the item page, and look in the Quick Info box on the bottom of the page. You'll find a link to the item on the manufacturer's own site with the most up-to-date details. Thank you, Newegg Support
