NUT relies on the data that is reported by the UPS. If the UPS reports  
the runtime is 51 minutes, that's all we list. However, chances are  
that you can either tell the UPS that additional batteries are  
installed *or* that running a runtime calibration will be sufficient  
to fix your problem.

We need some more info about the configuration. What should trigger  
the shutdown? Are there any other UPSes involved? As long as you have  
NUT clients for all systems involved, it is usually a matter of  
setting the correct POWERVALUE in upsmon.conf and systems will  
shutdown at the right time.
