A2337 MacBook Air Battery A2389 for MacBook Air 13 Inch A2337 Year 2020, Laptop Replacement Battery A2389 EMC 3598 MGN63LL/A MGN73LL/A(4800mAh/55Wh)

It comes with a very easy instructions! That makes it easy to install! Works well and the tool kit is enough to work. Worth for the money 💰

This is a solid aftermarket battery that includes the standard type of installation kit that you might expect to receive with most aftermarket replacement batteries for Apple products. This particular set goes beyond the expected by also including an anti-static mat made of foam sheeting, which I thought was a nice touch. (Come to think of it...that particular piece may have just been packing material, as I'm not seeing it included in the Amazon product listing - well anyway, it would certainly work as such, and that's how I've used it.) The battery was shipped immediately after I placed my order and arrived lightning fast! It came to me well-packed and secure, with a helpful 15-step instruction sheet with large, full-color pictures to clearly illustrate what needs to be done at each point in the process, which made installation extremely simple and straightforward. Usually, I expect to need to pull up Youtube before even attempting to do the install myself, but I felt confident enough to forge ahead without doing so, on the strength of the included how-to. Even though my 2021 MMacbook Air battery was still reading as "Normal", with an 82% maximum capacity and a 754 cycle count, I knew it was only a matter of time before it would need to be changed. Having put off battery changes in my Apple products until "Recommended" in the past, and regretting it, I thought I'd get out ahead of this one, this time around. For one, I really like my 2021 M1 Macbook Air, and once I find a Mac form factor that I really vibe with, I want to keep that product going as long as is possible. As for when to change your battery, I've found it's best to not necessarily go by the Apple battery usage metrics, but by when you find yourself re-charging your device more than you'd like to.As mentioned, both shipping and installation were exceptionally fast, stress-free and super easy. That's very important, as although I was lucky to get out ahead of the replacement cycle this time around, I'm usually not so lucky, as you can probably relate. Usually, by the time I notice I need a battery replacement, it is often well past due, which can also add to the stress. So I really appreciate the fast shipping, clear instructions, and the all-inclusive kit containing everything you need to complete the task.Everything fit seamlessly and my Mac powered back up after installation. So far so good! If anything changes, of course, I will be sure to update my review. However, this seems to be a great value and I am confident in recommending this battery to anyone with an A2337 Macbook Air!

Instructions, though printed on a color sheet, were still too ambiguous to be helpful. YouTube. I was afraid I would round the tips of the screwdrivers, but they survived OK. Quality of the battery seems fine. The wires to the main connector into the motherboard seemed a hair short, making it hard to get that connector in. If doing it again I'd plug in that connector, then screw the battery itself down.The screws involved are tiny, tiny. Like, heads of 1/16" in diameter. Drop one in carpet and you'll never find it. Go slow and be very organized.Battery came charged to 65%, charged just fine up to 100%, am in the process of running it down to 0%, then back up, as recommended.No reason not to recommend it. This job is doable but challenging the first time. Go slow and be very organized. When you take a screw out, make a note next to it where it came from. Took me two hours. If I ever did it again, probably 40 minutes.

I just received this battery and so far the life of it has been longer than my original one. The original battery was at 80% of its battery health. I also like that the instructions were clear, so there was no difficulty in getting the battery to fit and install.

Don't buy. A fully charged battery lasts less than an hour, and macbook shuts off when it says 72%. After one month of use, it barely holds a charge.
