Re: sensor load and life expectancy

The main reason for 10K load (or whatever is spec'd by the manufacturer) is to maintain temperature stability. A higher value will give you only a max. of about 1% longer life.

The only two things that I can think of to improve life is:

1. store sensors in dry nitrogen or Argon.

2. back bias the cells at a voltage very near the open circuit voltage of the internal sensor to reduce current generation.

Number 2 is difficult to do sense you don't easily know the open circuit voltage without opening the cell.
