Got this a few days ago. Works good so far. will update if it stops working. Note that I have a modified BIOS, so I don't know if it works with stock BIOS or not. Ran a calibration with `tlp recalibrate`, here's stats after that:/sys/devices/platform/smapi/BAT0/manufacturer = SANYO/sys/devices/platform/smapi/BAT0/model = 45N1023/sys/devices/platform/smapi/BAT0/manufacture_date = 2021-05-25/sys/devices/platform/smapi/BAT0/first_use_date = 2023-01-02/sys/devices/platform/smapi/BAT0/cycle_count = 3/sys/devices/platform/smapi/BAT0/temperature = 25 [°C]/sys/devices/platform/smapi/BAT0/design_capacity = 55500 [mWh]/sys/devices/platform/smapi/BAT0/last_full_capacity = 48640 [mWh]/sys/devices/platform/smapi/BAT0/remaining_capacity = 48640 [mWh]Charge = 100 [%]Capacity = 87.6 [%]
