1 out of 5 eggsBad Battery

Pros: none

Cons: This battery only lasts 90 minutes with low use.

My Macbook has an SSD installed, and the LCD was at medium light. I was just doing regular internet browsing, and I could watch the batteries percentage drop 1 point every 45 seconds. Not worth the money. DO NOT BUY

Other Thoughts: I had to wait over a week for this battery. It performs worse then the battery I was replacing it with.
