Hello all,
I have a spare cell with date code on it G4, what does this mean ? Where can I check expiry date?
Jan = A
Feb = B etc
4 = 2004
So as Phi said July 2004
It expires when it no longer can indicate a ppo2 of 1.6 (is the way I determine it)
This has been after 6 months, 10 months, 12 months - it can vary - suck it and see!
