Thought I killed M6R pack

I was reading an M6 thread and reached for mine, only to find it wasn't where I keep it. :thinking: I checked the bugout/camping bag where it has been since Thanksgiving weekend. :ohgeez: I pushed the button and nada. :( From the tailcap position, it may not have been locked-out, either.

This is where it got interesting! I checked it with my DMM and the reading was unstable as in jumping up and down. I assume that has something to do with the regulation circuitry. At any rate it was strange! I plugged it into the Triton and set it for 1/2 Amp. I checked the pack voltage a few times during the charge, and it continued to jump up and down. The charge terminated and I unplugged the connector. The pack was still jumping up and down (~9 - 10V) on my Fluke. After letting it cool to room temp, I dropped it in and it Lit! :) I started my stopwatch and did my first full burn, I mean run, and got just over 19 min, so I guess it's OK.

Is the self discharge of the NiMH cells increased with the regulation circuit?

IIRC, the regulation circuitry is always connected in that pack, so yes, self-discharge would be somewhat faster than if the cells were not connected to anything.
