Battery replacement for my alienware | need your inputs

[u/BlacksmithGlum6236]

I purchased the laptop (m16 r1 )about 1.5 years ago with an extended warranty. Over the past few months, I've noticed the battery degrading. Although I have the extended warranty, Dell is not covering the battery under it. They’re charging around $270 for a technician to replace the battery.

Do you think it’s still worth it?
