No worries about the hijack... looking forward to having our own stories like that!

In general, I find that lithium primary AND lithium ion batteries are both good for in-device storage. Better than other kinds IMO.

HOWEVER, things to watch out for:

1) As noted above, don't go messing with them in such a way that might short them out as you are asking for an explosion followed by dangerous, toxic fumes.

2) Be careful to store devices with high drain devices like a 2xCR123 flashlight in such a way that avoids accidental activation. If you activate your 2xCR123A flashlight in your bag, it might get hot enough to melt or even catch something on fire.

2a) Even without the hazard, it is counterproductive to store devices with batteries if they might accidentally be activated since the batteries may be dead when you need the device.

3) I would be careful to avoid storing any batteries for long periods of time in devices that maintain small draw from the batteries (soft power). Not a hazard, but, like 2a, it doesn't do you any good if over time the device saps the power just sitting idle.

One obvious solution for things like flashlights is to loosen the tailcap slightly so it cannot be activated. I carry a Zebralight H30 headlamp in my pack w/o fear of problems or accidental activation for example.

I have a flashlight like this and it drains a full cr123 battery in about a year.
