I come from 3rd world country (hence small monthly wage), and any pricier battery sold here having the same quality as the 15 USD battery (there are no original or near original battery sold here, and last time I tried to soldered new battery cell, I failed, miserably).

I need advice, because I don’t plan buying new laptop, but need to be mobile (move around). X220 still fit my need and and I’m using up to date OS (Fedora 38 XFCE)

Any suggestion is appreciated. Thank you!
