Question about cells???

Hi all,

My question is....during a dive last week to 60m for a BT of 36min RT 103min, My inspo/vision had a cell variation between C1 and C2. Whilst pumping up the O2 manualy to 1.4pp at 6m for the last of deco, cell 2 showed to be a lot slower reacting to the change from 1.3 to 1.45 than cell 1 and 3 (was very sluggish).

Called up C2 but the cell seemed to be reacting as expected and inline with the other 2 cells for pp reading whilst C1 was still showing it up to be slow in reaching above 1.3

During the descent all cells showed to reach above setpoint 1.3pp(reaching 1.5pp triggering high pp alarm on HUD and buzzer) Confused i put a multimeter on the cell to night it only reached 7.1mv

Not knowing what they read when they were new i tested the other 2 cells both of these read around 7.4 to 7.6mv
The cells were manufacterd july 2005, my unit was new from AP in December 2005. AP state the cells should read 8-12.5mv in air, whilst teleydine state 7-13.5mv is ok.

Any thoughts???
