| Cell Replacement
There's been a lot of discussion recently about cell replacement so I thought I'd ask this question separately:
"What are the options and why?"
The basics I can think of are:
1) Replace all the cells at the same time (i.e. all 3)
2) Replace 1 at a time:
a) As a drift or other issue is noticed (cheapest option)
b) At a predetermined interval (i.e. 365 days)
3) Replace a majority at a pre-determined interval but leave one "old" cell in place
I don't like (2a).
With (2b) and (3) I am thinking that having a reference cell that gives some warning against infant mortality problems is a good idea BUT it does require some discipline.
With (1) the main issue appears to be the batch manufacturing problems I have read about elsewhere i.e. there is a chance of getting all bad new cells. Also there is a risk that all the old cells drift/fail in the same direction and such a problem would be more difficult to detect.
I am assuming no "independent" monitor is available (if so should use a different cell type?).
