RE: Spyrus Battery Power Consumption

The Spyrus unit automatically shuts down after a 90 second idle period.  This time was in the calculations already presented below (see low power for 90 seconds.) 
I'd just let the Spyrus do its own power down and not add to the pollworkers' confusion.

Ian: Would you recommend that the pollworker turn the unit off after each voter card is programmed? What do you see as the best election day procedure for pollworkers?

Subject: Spyrus Battery Power Consumption

I finally have some info from Spyrus on the consumption of battery power. 
Sitting on the Shelf   
The Spyrus units lose battery power just sitting on the shelf.  After installing a fresh set of batteries, it would take approx. one year before they died.
Operation Scenario
On a fresh set of batteries, and based on the operation model noted below, the Spyrus can program approx. 1300 smart cards before needing another fresh set of batteries.
   Operation model:  Assumed each operation takes 2 minutes, and during the two minutes operation, the smart card is powered on for 20 seconds.
    During the 2 minutes operation, the PAR2 is running at full power for 30 seconds, and low power for 90 seconds. When the PAR2 is
    waiting for a key input, or processing a command from the Diebold application, it would be running in the low power mode
As an example, taking both power consumption factors into account, a Spyrus unit never used after fresh batteries were installed and sitting on a shelf for 6 months would have 50% battery power left.  It would therefore be able to program approx. 650 smart cards (half of the 1300.)
