Could have had 5 stars. 1

This battery replaces the original which was dead in every sense of the term (about 600 cycles, state of 5% according to iStat, autonomy 15min and above all, she inflated !!!).
This battery fit fine in my aluminum macbook late 2008 (A1278 / A1280). The underside of my hull remains deformed because of the previous battery. However, my trackpad is not bulging.
Compared to the autonomy of the original it stands behind, at 77%, it takes 1:43 of autonomy (against approximately 7:30 with my old 100%) knowing that I've just install it. It is 1 cycle and its condition is 95% against 98% and 1 cycle.
The price is in the area of ​​competitive products.
