Of course it varies from location to location.  Generally, after 8-12
hours we will start seeing infrastructure problems as remote batteries
run down.  Providers will be re-charging batteries with portable
generators, but predicting battery lifetimes is as much art as science.
Sometimes the battery doesn't last as long as predicted.
