55
Should I be concerned about this mildly spicy pillow?

I only ask because the bulging seems slight enough that I'm not 100% certain that's not just how the battery is supposed to look.
This is inside a Lenovo ideapad flex 4. I only opened it to replace the hard drive.
I mean, it's not going to start bulging less from here on out. Unlikely to burst, but should be replaced for safety and performance. You've already done most of the work by opening it up!
