A1278 A1322 Battery, SKOWER Replacement Battery for MacBook Pro 13 inch (2012 2011 2010 2009 Version) 661-5229 020-6547-A 661-5557 MB990LL/A MC374LL/A MC700LL/A MD101LL/A

Been a couple weeks. So far so good. Not sure if it lasts as long as OEM battery, but does the job. My 2012 MBP was finally giving the warning symbol that the battery had an issue. Pretty generic warning, but it usually means the battery needs replacing.I wouldn't hesitate to buy this again. For those that are giving it bad reviews, you are either getting a lemon (just return it) or you aren't following the proper charging directions:1. Install new battery2. Start computer and verify Battery Condition is OK (in "About This Mac"/Details3. Run computer until it dies completely. iTunes or YouTube on Autoplay should do the trick.4. Fully charge battery while computer is OFF5. Repeat steps 3 and 4 again.Your new battery should be running in peak condition.

I got this battery for my sisters older MacBook Pro unibody because the previous battery was no longer good. This battery is great it last around 5-6 hours on normal use of the laptop. It makes the computer much more usable because before the battery would die in just 30min. Great product looks exactly like original and comes with two screwdrivers which is nice.

Aawe my macbook pro has some life left!!! After having over 900 charges on the original battery, she was dead. New battery, new life. This old mid 2012 macbook pro might have some life in her yet!!

Easy to install and getting the job done. Doesn’t have a great battery life.

Wonderful. With a YouTube tutorial on how to replace the battery, I saved over 200$. An Apple battery replacement is 250$, I paid 30$ to do it myself. I am really happy with this.

Battery is faulty, I tried customer service but got no response

Do Not Buy. Already burnt out. Installed 1 month ago. My computer has to be plugged into work.

Inexpensive fix for a battery replacement on my Mac. Came with the tools, easy to install and shipped fast
