Li-Ion 6600mAh battery (11.1 V), black, computer Asus X53B, X53BR, X53BY, X53E, X53S, X53S (model 2011), X53SD (model 2011), etc. X53SV (Electronic devices)
Despite the size of the battery and its operation I doubt the greater autonomy from the core battery. I do not reach more than 4 hours of battery life.
