Input: I've only owned this battery for just over 2 months. It's been a lifesaver. It probably worked better than my original Macbook battery until it unexpectedly stopped working last week. The battery shows 100% charge on my Macbook screen as well as the light indicator on the battery itself, but if I dare unplug my Macbook, my computer completely shuts down within a few minutes without as much as a warning. It does not reboot until reconnected to the charger. Disappointing to say the least.

Worked Great for 2 Months
