Mike,

  Got one of those, installed it and intentionally let the Burb sit for 6 days.  Opened the door today, nothing.

  So, got in and hit the brake.  Nothing.  Turned on the key (blower had been left on) and everything woke up.  Yippee!  Fired right up.

  I have one of the Shumacker chargers with the battery voltage and % charge readouts.  11.7 volts and 33% charge, just like the literature said it would be.

  It's not often something works as advertised but this one did.  Thank you very much. NAT helps again.  

Take care.  Stetts

PS.  Of course, I still wonder what the actual problem is, but not so much anymore.  <g>
