A1369 battery for macbook air 13 Late 2010 Mid 2011 Mid 2012 Mid 2013 Early 2014 Apple A1377 A1369 also fit A1405 A1466 A1496 661-5731 MC503 MC504 [Li-Polymer / 55Wh/7200mAh

I just replaced this, and it is working perfectly in my mid-2013 13" MacBook Air. I'm fully satisfied at the moment. If it continues to work perfectly I probably won't remember to come back and update this, but if it starts to fail I will certainly - so unless this is updated you can assume it works well.The battery itself seems to fit perfectly without being too large and causing touchpad problems as noted in other replacement battery reviews. The capacity was recognized by the mac as 7500mAH which is more than the stock battery, and as advertised for this one. Charging time for initial charge appears normal and I'm hoping battery cycle time appears normal once it's in regular use (will update if not).The tools that came with the battery are not great but it is only one replacement so they don't need to be. A common problem with screwdriver bits this small is that they strip out. This happens with most of the toolsets for opening modern laptop and cellphone cases. If you work on these things often, I discovered this economical set of hardened steel bits, and you may find it helps https://www.amazon.com/gp/product/B01M14MB9JI had that hardened steel set but tried to use the included drivers to see if they were sufficient, and they were until replacing one slightly sticky screw - the last one - where they were able to do the job but started to fail right at the end. Which I think is the definition of "perfect" - lowest cost possible but they did the job? Just be careful or order a set of hardened steel bits.

My computer misreads the charge level... I love playing guessing games, but this product doesn’t seem much better than the old battery it replaced.

It does jut out of the laptop a bit on one side, so I can't say it is the ideal size for my Macbook Air A1369...

Very easy to install.

This battery is not reliable. It says 19-15% battery level and then suddenly labtop shut down. I could not restart my mac unless I plug in the charger. And when the mac restart, the battery level shows 7%. This happened 5-6 time in the past 2 weeks.

It does not hold its charge at all, I have to leave it connected to my macbook air charger just to use it. I'm disappointed with this purchase. Its so bad that i'm going to need to put back my original stock battery. Maybe I just got a bad batch and the seller can remedy this issue.

This has worked perfectly. It was an easy fix and worth the money.
