Hey guys, new to the light scene so bare with me here. Just picked up a Fenix PD31, and an Ultrafire 18650 battery and charger. I've read a lot of the threads about Li-ion batteries so I think I'm pretty good there, but I'm wondering what everyones charging habits are. If I used the light for 10-15 minutes total in a day, is it worth taking the battery out and charging it back to 100%? Or should I just leave it in there and use it a few days and then charge it back? I'm not sure if the use I'm putting it through is enough to warrant a trip to the charger, or is it always best to top of the battery whenever possible? I also don't want to wear out my light by pulling the battery in and out every day, if that's an issue.
