Was reading through the manual and came across the bit about cell ranges being from 0.8 to 1.3 mV and decided to do some tinkering.....

Previous owner installed a new cell when I took possesion and labelled install dates on the cells...
#1 - 2/07 - s/n 60844871
#2 - 12/07 - s/n 71120735
#3 - 2/07 - s/n 60844872
-------------------
When I pull up System Monitor (from the secondary) I see the following:
.22 9.7
.22 12.7
.20 8.7

Unit was calibrated a bit over a week ago over at Padipro's...

Is this low mV output and inconsistency in relation to the other cells an indication that that third cell is on its last legs...?

Should I recaibrate and pull values again...?

Training is the end of next month; how many spares should I have on hand...

If it's in range don't worry about it. Each cell has a different voltage. You could have three cells at 9mV, or three at 12mV, or a mixture of both and somewhere in between.

Don't worry about it.
