New Laptop Battery Compatible with MacBook Pro 13'' A1322 A1278 (Mid 2009, Mid 2010, Early 2011, Late 2011, Mid 2012)fits MB990LL/A MB991ll/A MC374ll/A MC375LL/A MC700ll/A MD101LL/A MD102LL/A

Great value and very easy to install - fired my dead Mac right up.

I use my Macbook in counseling to take notes and keep records. it was very disturbing one morning when it no longer functioned properly. The new battery was easy to install and everything is functioning well again.

First purchase, got SIKER, has been a fine battery. Second purchase, got SIMER, a fine battery ONLY for 3 months 9 days, passed the 3 months return coverage. It did not hold charge anymore. Macbook works fine when I reinstalled the old original battery. I made sure I installed this SIMER correctly, problem persisted while the SIMER battery installed that I could only use the mac while charger plugged. Ultimately reinstalled the old original battery. As a note, it has been sitting in my room desk as of purchase on California room temperature, so NO, it suffered no abuse whatsoever.

Arrived packaged well, no damage to shipping or product box. Fits well, and followed calibration instructions (thanks Google) and battery lasts DAYS between charges when in sleep mode. Before my last battery died, I'd leave my MacBook Pro in sleep mode for 6 hours and would have to plug in so I could turn it back on.

First the Good, the battery works fine, no issue there.The Bad: Safety instructions are included, but no installation instructions. It is not complicated and a youtube search will show you what you need. More of a concern are the 4 screwdrivers this ships with. I only needed two for my model, but taking the back cover off the first screwdriver failed after 3 screws. They are very soft. The second screwdriver failed after tightening the second screw on the battery pack. I had the drivers from my previous battery swap and they worked, but should you not have replacements, you may be in for a bad time.Again, the battery works fine - so not a deal breaker at all, just something to keep in mind.

Fair purchase sure you could find a stinger life battery at a higher price point...

Very good quality for the price. Have only had it 2 weeks but am very impressed with the charge it holds and how long it holds it for! Very happpy. Will definitely order again if I need another. I would highly recommend this to anyone looking for a replacement battery for a Mac book pro!

Exactly what was ordered! Can’t get better than that!
