X220 with non genuine battery - Firmware update

I am using a non genuie battery in a X220 without any problems.

 

Now I want to make a Firmware-Update from 1.28 to 1.43. Do I have to expect that the non-genuie battery with firmware 1.43 may no longer be charged?

Welcome to the Community

x220 doesn't feature genuine battery authentication, in any BIOS version. So, don't worry.

ThinkPad 25 Special Anniversary Edition. #retro. Signed by D.Hill

Do it well, worse becomes itself

I updated to firmware 1.43 and the non genuine battery still works. Thank you.
