In June, we were reporting about a new TruePower battery from Fastmac and dedicated to MacBook Pro 15". Its nominal capacity was higher than the one offered by Apple, and its stability over time is indeed superior to the original one.
So after 60 cycles, and a complete recalibration, we obtained the following results:
Once fully charged, it almost reaches 6000 mAh, whereas from our own test the original one from Apple would have already substantially decreased its current battery charge.
