what cells are you using and why?

**kybrt** · 3rd May 2008, 00:00

if you were in say, ny and you needed new cells for say, sunday, for a rEvo, what would you do? can you use a generic AI replacement or does paul do something special to the cells he supplies?

Its an R22 D

Just like any other R22 D

just not a standard R22D, the minimum output voltage must be 9 mV in air

we now have R22D-rEvo that have that spec, same as the AI-rEvo

Hi Paul,

Just curious, did you have both or did you turn "definately" to Teledyne?

In any case great thing that you test mv output before sending them

nothing is definately in life: Teledyne's aren't perfect either...

we keep testing both, at the moment we supply R22D-rEvo

Paul why did you choose 9mv as a minimum?

there is some belief in the fact that lower output in air cells actually last longer than higher output in air ones!

Marv,

I'll have a few new AI R22 D's with me Sunday if your stuck....

They read 10 - 12 in Air.

thanks richie,

i got a set from DRE as backup, psr 11-39-md type

havent checked them on the cell checker yet.

the cells i have are doing this which has me concerned

mv in air in 02 @.6 bar .7 bar .8 bar
7,0 44.0 49.1 55.0
7.4 47.6 53.6 59.7
11.9 74.9 84.7 93.6

maybe its my skil at graphs or math, but i think the first two are done for.

opinions?

hello Dave, the smaller you make the span of allowed voltage, the less error you can include when calibrating: the unit will reject the cell as beiing to low or to high
