That would depend on your chemistry choice. Apples to apples (16340 vs 14500), the D10 has a LONGER runtime.
But because of the form factor, the D10 gives you MANY more choices as to how to power it. Alk, lithium primary, NiMH, Li-Ion, LiFePO4, etc.
Interesting...I didn't know that. I'm going to have to look into the other battery chemistries. Thanks for the insight! :thumbsup:
