Strange problem with my Fenix P3D-CE

Spypro · Sep 20, 2007

My little P3D is acting strange... here is the story.
I'm using AW RCR123A.
All of a sudden the light stop working.
When I look for the voltage with my multimeter one of the cell is about 2.40v and the other cell is 0.00v !
The light does not flicker at all.

What do you think ? Is it a common problem ?

Big thanks !

Lemmie know if anything explodes! Really though shouldn't you throw away the flat cell? Or am I remembering it wrong?

If you are useing the AW RCR123A then they are probably 3.7 volts each.
You cannot use anything other than 3.0 volt cells for this light. I had the same problem/question and thought something was wrong with my Fenix.
I now use the 3.0 volt RCR123A cells and have no problems.

You can use 3.7v r123's you just have a bad battery.

If the battery you are using is higher than 3.0 volts then the
light will only produce at the highest output setting.

Would a protected cell that has been drained to it's lower limit give a 0.0V reading if the protection circuit isn't allowing any current out? Should he try charging it?

I use tenergy RCR123A 3.0 volt 900 mAh batteries with no problem in my P3D RB100. They were 4.2 volts each, a day after I took them off the charger. http://www.batteryjunction.com/4parc390reli.html

this is the p3d all modes will work fine with 2 3.7 volt batteries.

Spypro,

You have drained your cells down to protection mode. The LVC of the 0.0V cell has tripped and need to be recharged/ reset.

This is true with the P2D, but not the P3D.

With the P3D, the voltage cannot be BELOW 3.5v.

I don't know why my P3D does not flicker... is it normal ?
With SF CR123A the P3D is flickering when the cells are low but the RCR123A, no flickering at all.
I don't want to damage my cells.

The protection circuit on a RCR123 kicks in when there is about 2.7V left in the cell. Times two that is 5.4V. The P3D doesn't start flickering until 4V is detected.
