Just bought a battery for my Macbook. These are the details. As far as i know original batteries manufacturer is SMP not simplo. Also strange thing capacity went down to 89% just after 1 day ?
MacBook Pro, macOS Sierra (10.12.3)
I know you probably have found resolution to your question already, but my factory battery is by Simplo. Apple uses more than one vendor for its batteries and even if the one that came with your laptop originally is by SMP, others of the same model came with Simplo batteries.
Also, my MacBook has its factory battery still and the battery was manufactured 1.5 years before being installed in the laptop by Apple themselves (I purchased this MacBook new at the Apple Store).
Cannot say.
I took the MBP to Apple Store for battery replacement.
Here is the info about the battery replaced by Apple about 5 months ago.
If you got the battery from Apple, it comes with a 1 year warranty and you can have it evaluated for possible replacement.
Ciao.
Coconut shows the battery was manufactured in February 2015. Doesn't seem new to me. A battery who's laying 2 years on the shelf is not conducive. You should contact the supplier.
Genuine Battery or knockoff ?
