Last year i replaced my hp x360 440 g1 battery from a techie: https://techiestore.in/ , the battery is really good i get good backup aswell. The only issue i have with it is that i get a White screen stating that battery is not original everytime i boot the laptop up and im required to press enter. The issue with this is every time theres a windows update and i restart the laptop the laptop keyboard stops working and i cant press ENTER on the 3rd party battery screen. plugging in an external keyboard is the only way i could proceed with updates.
