This is my 2nd purchase with storebatteries for my 2011 mbp. First battery lasted 5 years 2016-2021, now begins the 2nd battery. Hope it will last another 5 years. The first battery died without any float, and gives more than 30 cycles from under 80% capacity to completely dead at 1.8%. One minor issue is that this time the alignment of screw holes is not so good, it is hard to put all 3 screws fit, but 2 is fine.
Adding comment: 1. Super good customer service as in they helped to make sure i am purchasing the correct modal battery by a few email conversations with old battery photo
2. Delivery quite fast, it reached me in 8 days after modal confirmation.
