Where can I find laptop batteries?

Question

Batteries

I have a clevo w740su laptop. The 11.1v battery has two elements swollen (thin and flat in a "chrome" shell), where can I find these, what to solder? In Windows it is written that replace the battery, then it is recognized as faulty. I would delete these two and continue to use it - the battery is needed for carrying, and without it it becomes a hospital.
Ps: there is no such battery on Ali, in Russia too, I did not find such elements. How to find and where, help.
