Aftermarket batteries are a crap shoot, but I think you run into counterfeits as well. One thing to do particularly on Windows is to use Vantage to set the maximum battery charge - if you never charge past 85-90% lifespan should be longer with little enough capacity reduction that you won't notice it. The 10 minute one probably has a bad cell.

>set the maximum battery charge That's interesting. Does anyone know a way to do this on Linux? >The 10 minute one probably has a bad cell. I wonder why batteries are always hard soldered and glued. I guess it saves space and is cheaper, but it would be so awesome to pull and replace cells with the ease of a battery cage.

  > Does anyone know a way to do this on Linux? Install 'tlp' and 'acpi-call-dkms', then do 'tlp recalibrate BAT0'. This will completely discharge the battery and afterwards charge it to the possible maximum. Then run 'tlp-stat -b' to see the capacity.

  echo 80 > /sys/devices/platform/smapi/BAT0/stop_charge_thresh As usual more information is in the Arch wiki https://wiki.archlinux.org/title/tp_smapi https://wiki.archlinux.org/title/tp_smapi

    Interesting, though it looks like tp_smapi stops around the T410 or T420 so maybe ~2010 systems? The workarounds for unsupported devices has relevant options for more modern systems.
