What you are observing is exactly what will happen as the battery reduces capacity. We don't have a calibration procedure so the SOC assumes 3100mAh. The SOC is a mAh/1% counter. After so many mAh it subtracts 1%. The critical level is a voltage reading. Its not coupled to the SOC. So with a battery that has less capacity you will reach the critical level sooner. Whats the serial number of your battery? You may also want to run a olpc-pwr-log run with that battery so you can determine what the actual capacity of the battery is. -- Richard A.
