I know this is a noob question and I have been Googling the web and CPF for 45 minutes trying to get a straight answer so I apologize if this information is somewhere else. I have had a P1d CE Q5 for a while. I just ordered two lights from DX and got some 3.6v rechargeable Li-Ion batteries with it (SKU#: 8683). I am trying to find out what the ramifications are of using those batteries in my P1d. I understand I may lose modes for the first few minutes due to a higher than expected voltage but which modes do I lose? I really could care less about modes so it doesn't affect me as long as I still have the "turbo" mode. Is there any actual danger associated with using them? I am not too concerned with run times as I will have some lights in my car and some in my apartment and will have spare batteries by them always and don't use these things for that long at a time. My other question is exactly how long will these batteries last not being used? How long can they sit in my car, in the light or just in a drawer and still retain their power? Thanks guys!

You will only have turbo and strobe. Low and Medium will turn into turbo modes.
Left unused, Li-Ion's have a very low self discharge rate. However, do NOT store them in your car. Prolonged storage at high temps drastically degrades them permanently (cannot be recovered).

Thanks for your response. Do I run any risk (damage wise) of storing the light/batteries in a glove compartment/center console or using those higher-voltage batteries at all?

The light can withstand car interior temperatures comfortably, just not the rechargeable battery. Ideally for car use, you should use a standard lithium primary cell, which combined with your P1D makes for an in-car light that can withstand anything you can throw at it, -40 to 140 degrees.
The rechargeable cell won't damage your light per se, however it does reduce the lifetime of the LED slightly since you're driving it harder. A candle that burns 10% brighter lasts 90% as long. But this only matters if you run the light for hours a day and plan on having it around many years from now, otherwise in common/everyday use, it's not a factor.

The output would be slightly higher for a short while, then settle at the same level of turbo.
