Ok, this is definitely working now. 4 hours and 30 minutes of video playback (Looping a movie using the Movies and TV app) at 40% brightness and 10% volume. Still 60% strong. Still falls into “light use” (look at HW info chart, Movies & TV UWP app is quite efficient), but still, this is over 8 hours of battery now. Before it was less than 3. Least I can do is recommend the seller (H BBA). And, I also recommend checking the voltage of the cells when you first get them. If it is not equal for both of the cells, charge them manually. Be careful not to overcharge them, though. Watch the temperature. It would have saved me a big headache. Paco
Hello @Paco, thanks for your help for this great device. I ordered the same batteries from the seller you recommended.

I plugged them in my laptop, and now i can use my laptop anywhere, not just connected to the power plug (was a disaster for a laptop before)
But i dont understand something, your and almost everyone’s screenshot of battery bar shows the same capacity 48.000 mwh but mine shows only 36.480 mwh.. why is it like that? the same laptop, same seller and battery. do you think now its only working 1 cell but not the second one? Any advise? @chupa
