Re: How long can the battery run the compressor?

OK...

The compressor pulls 10.5 amps nominal at "full load" as per: http://www.drillspot.com/products/35..._Va cuum_Pump

The Battery will reach 1.6 volts per cell (full discharge) at a 1C (10.3 amps nominal) discharge rate in one hour as per http://www.batterystore.com/Yuasa/NP18-12.html

In gross terms, you can run the compressor continuously for a little less than one hour.

Disclaimer and warning: The compressor is going to get really hot if you run it continuously. I'm guessing that you will cook off the internal lubricants and seize the pump way before you discharge a full battery...

JMHO,

Mike
