D10 minimum operating voltage?

[BruPri]

Using Eneloops, I removed a previously working battery while attaching a belt clip, when I re-installed, no light. :thinking:Checked the voltage: 1.169v
Most of my charged Eneloops have a nominal voltage of 1.337v Anyone know of a test that may have been done to determine the minimum charge needed before the light completely dies? Trying to determine if this is normal, a battery problem or possibly an issue with my particular light.

Thanks much,
Bruce

1.169v is on the steep downhill discharge curve of NiMH batteries. Its probably much less under load. Here's a pertinent thread: http://www.candlepowerforums.com/vb/showthread.php?t=229965

Edit: There's also a discharge curve here a bit over halfway down for Eneloops. http://www.candlepowerforums.com/vb/showthread.php?t=79302

that voltage roughly means your battery is dead.

charge it

Thanks SL & CSSHIH, useful information. I popped the low battery into an Innova AA light and it worked fine but I imagine there's a boost circuit in the D10 that draws more accounting for that.
Issue resolved, chalk it up as a non-problem...
