Yep, and that's where the eneloop excel.Guess I use a light less than others! I had a single 123A head torch which used the same battery for at least three weeks of actual camping, might have been five weeks. I know that 123As are much more power dense, but multiple AAs in a single weekend :yikes:.
I haven't tried Eneloop, keep hearing good things about them. None of the other rechargeable AA batteries that I have used have held charge anywhere near as well as standard AAs. They have simply run down while sitting unused in the torch.
They hold charge even when not in use... And they perform just as well as the alkaline in my opinion, the problem is the non rechargeable ones seem to be 1.5 v and most rechargeable ones only come up at 1,2 v .
Why ? I have no idea , but eneloops really make a difference.
