I have been running "MiniBattery Logger" since I purchased my 2.5 Penryn MBP last month. After checking out the shared data from other users, I noticed the 15" models have two battery capcities, 5500 or 5600 mAh. Does anybody know why Apple put two different batteries in the same model. Also, I noticed the 5500 versions are made by SMP and the 5600 is a Sony.
Am I just loosing my mind, or is there in fact two different versions of the 15" MBP battery? The only reason I am bringing this up is because I have heard that past MBP batteries have been less then perfect, as evidenced by there 3 star rating on apple.com. I am wondering if the Sony batteries are any better in life cycles compared to the apple ones.
1.) It's analog, there will always be some variation.
2.) Where do you get this info from? In System Profiler I don't see anything related to this (I have SMP). I only see the full charge capacity on mine at 5297 mAH. Guess I have the super small version.
3.) Don't stress it. The difference between 5500 and 5600 is small enough that in a year you won't be able to tell the difference due to battery wear.
