[oclug] Batteries

[Dean Staff]

On a lighter note....

You could do away with the Battery backup altogether. Home Depot has 
a backup generator that goes for about $4500. It ties into your house 
line and kicks in the moment the power goes out.. You would only need 
the batteries to cover you for the time it takes the generator to 
kick in. Plus a battery backup is better at protecting you from 
spikes.  ;-)

Just a thought...
