 OK prompt command "watch-battery".

 Oh. Sorry. I thought you were referring to the value shown by sugar which
 does not match the EC.

 What tool are you using to capture you logs with?  Its not 'olpc-pwr-log'
 Your tool does not capture the ACR value so its difficult for me to tell
 if your batteries are not meeting capacity specification or if its the SOC
 % calibration.

 Please use olpc-pwr-log to make battery logs.  It captures all the
 necessary information for battery diagnostics.  olpc-pwr-log is included
 in the OS build.  You can run it from the command line.

 I'm in the process of verifying the 1% SOC value for the 1.75.  I'll
 provide new firmware when I have that complete.
