Thank you for your reply! I was bored today so I decided to put the battery in anyways; I followed OWC's guide on Youtube. I'm charging it back to full now after draining the battery and letting it sit overnight. CoconutBattery says that my battery was made in very late 2019, so hopefully I got a good one! So far my MPB is running about 20 degrees cooler. We'll have to see how it goes...
I planning on rarely using my MPB on battery power, so as long as I get 2 more years without swelling, I'll be a very happy camper.
That’s good news. I’m sure it will perform well for a year and then maybe in year two you will notice a faster drain. I am on my fourth battery counting the original. I just want to be able to sit on the couch for a few hours wire free. So far, my current eBay Apple OEM battery is the best yet, but the funny part is coconut tells me it’s failing or something like that. It’s got like 10 cycles on it.
