Hi,

If I understood you correctly, you want to save that setting permanently.

To my knowledge this setting won't be saved - the value will be 
restarted after you restart your system.

There's one way to keep the setting, even after restart. You will have 
to edit /etc/sysfs.conf  (this is for Debian, I don't know if that's 
where you'll find it on Gentoo but this is configuration file for 
setting sysfs attributes so you may search for it...)

Add this line to the mentioned file:
devices/platform/smapi/BAT0/start_charge_thresh=10

BTW, here's what I use, if you're interested:
devices/platform/smapi/BAT0/start_charge_thresh=40
devices/platform/smapi/BAT0/stop_charge_thresh=70
