Re: sensor load and life expectancy

The load resistor would close the circuit and hence allow current to flow continously, therefore removing the load when the cell is not in use might extend its life.
Basically no.

The circuit looks roughly like this

Add/remove a 10K load across P1-P3 and you will make less than 1% difference to the current consumed.
