Power LED red. Sugar says 2% battery but works!
Reboot
- ok bg-acr@ .bg-acr (no batman.fth/batman-start)
ACR -526.32 , LED red, Sugar 2% battery
poweroff
-remove battery 
-insert battery
- ok bg-acr@ .bg-acr (no batman.fth/batman-start)
ACR -566.32 , LED red, Sugar auto shuts off
Tried also after batman-start/stop remove battery etc,  no difference LED red, Sugar auto shuts off.

Booted another OS, power LED red but works fine with battery (used it for 10-15 min)

Moved the battery on another XO just in case, power LED red, Sugar auto shuts off.
Booted up with battery, plugged AC,  power LED stays red. Remove battery,  power LED stays red! Powerd off with AC power LED stays red! Remove AC, power LED went off.
Booted without battery, inserted battery, battery shows empty and charging. Charged to about 15% slowly, then jumped to 81% and then 97% in under 1 min and the power LED turned green! 

Now, you are going to say again that I do not know what I'm doing, but sure none of these looks very normal behavior to me and may have to do with how the battery "communicates" its state than its state per se.
