Decided to finally do something about the MacBook Air's battery

Since buying the Metabox N850HJ laptop, I had been using it as my primary computer. Yes, I didn't use the desktop PC as much as the Metabox laptop.

My wife has been using the aging MacBook Air. She hasn't been treating it well though. Its battery was in a very bad shape, and she doesn't keep it charged. So every time she wants to work on it, we have to first let it charge for a few minutes, otherwise, it would be very sluggish. I started observing this behaviour after upgrading to macOS Sierra. After upgrading to High Sierra, it is still behaving the same way.

This is the current state of the battery. It only holds 30% of the original capacity. It's funny how it says it's only done 713 charge cycles. I thought the battery was good for 1000 charge cycles before degrading seriously.

This could well be the last MacBook I would own because I cannot justify spending Apple prices. So I decided to buy a replacement battery for it. Apple would charge $189 for their "battery service" which I think includes a new battery but I wouldn't be surprised it didn't. I didn't want to pay that much especially for a 7-year-old laptop, so I went on eBay and ordered a cheap compatible battery. I don't expect it to be as good as a genuine OEM battery, but if it gives me several hours of battery power without blowing up, I would be happy.

The battery should arrive next week and this will the first time I open up a MacBook Air. Hope I don't kill it.
