Due to self discharge of rechargeable batteries I don't bother with them in any of my LED flashlights, I instead use alkaline disposable batteries and change the flash light batteries every 3-5 years and have had great luck doing so.
For cameras I do use 2500mAh batteries and have great luck with them, my video projector, MP3 player, phone, lap top, drill and electric car all have their own rechargeable batteries and I don't have any issue with any of those, I also have a rechargeable power pack that has a 12v and USB-5v output on it that works great as well.
