I changed the battery in mine around april 2018 with a kit from iFixit. The procedure was surprisingly easy, given the horror stories I had heard about having to fully take everything apart and use solvents. I just opened up the case, unplugged the battery and went at it with one of the tools. It came off in like 10 minutes. Sure, it would've been better for it to not be glued, but oh well... In my case it started swelling, so I figured I'd better change it before it burns down my house or something. I rarely use it on battery, so the battery life itself wasn't an issue. It was still able to run some 2-3 hours. The replaced one gets me around 4-5 hours, similar to my work provided 2018 HP ProBook 13" with an 8th gen i5u, which is also noticeably slower.
