Checkout the 'runtimecal' option from 'man 8 blazer' to give a  
slightly better way to determine the state of charge on the UPS  
(provided it reports the load).

See 'man 8 clone' which will do just what you want. The development  
version allows you to override the build in low battery detection  
altogether and set your own levels.
