Hey guys!

I call upon the vast knowledge of these forums,
I have bought a HP Envy 14-1193eo and I cannot figure for my life which battery is in it.
I have googled with no luck.
I need to know, because I wish to extend my batterylife from the 3 hours default, to the 7 hours optimal!
Also, I heard someone talking about an "add-on battery", does anyone know of this?

Hope to hear from you!
