BD LT Battery

Works well!

Great to have

Always nice to have a spare battery in your pack. Easy to switch out.

Nice headlamp, poorly designed battery system

I really like the Distance LT 1100 headlamp, but the interchangeable battery system is really poorly designed in multiple ways. First, the battery is attached to the headband, and to swap in a new battery the headband must be taken off and put on a new battery, which involves two small parts (one on each end) and is fairly difficult to do under ideal circumstances (such as at home with dry hands). Don't even bother to try in the cold, wet, or other adverse outdoor conditions! Then, the lamp must be clicked into the new (charged) battery, which is also difficult, and involves moving a very small catch (see comments about about the dexterity needed for this 2nd step as well). Finally, a discharged battery can not be recharged without the lamp attached, so there's no way to charge one battery while using another for the light! I will be keeping the system anyway because the headlamp itself is worth 5-stars, but the interchangeable lithium battery system is basically 1-star (hence my 3-star overall rating). My recommendation: just buy the headlamp and skip the extra battery!
