Battery seems to keep its promises, higher / heavier than the original (Asus EeePC 1001PX)

I managed to get 8 hours of talk time surfing the net and leaving the PC idle intermittently.
In more intensive use, I still 5h30-6h autonomy.
I have a 25% uptime Superier to the original battery, which dropped me after 4 years loyal service.

The little "flat" which is not really: the battery is heavier and taller than the original.
Suddenly, the netbook is a bit surélévé back.
It can be more like a minus, but I see it as a plus because I find the keyboard tilted forward more comfortable :-)

I passed on the aesthetics, the battery is black on a white netbook, I do not care.

I possibly would attribute a fifth star if the service life of this battery gives me satisfaction (perhaps 3 or 4 years? :-))
