Can a bad/damaged battery cause cpu to overheat!!!

Long story short, I have a serious overheating issue; constant thermal throttling, the CPU package temperature reaches 100°C and stays there, while the GPU is at 75-85°C range. The clock speed is stuck at 400 MHz ! The laptop is unusable and won’t last 1 hour on battery!

So I took a leap of faith and opened the case for first time to repaste cpu/gpu I noticed the condition of the battery, it looks terrible for a new laptop! I’m thinking of replacing it with original Razer battery as a last resort to overcome the heating issue!

Btw, I’ve tried repasting with PTM7950 and recently with Grizzly Kryonaut Extreme, but neither worked. I live outside the US and we don’t have a Razer store!

Razer… I would appreciate it if you can help me with a battery replacement or direct me to an official/certified online Razer battery seller!
