WHAT!!? i says on the battery pic " can only be recharged when fenix ARB-L1S batteries are used" and that your can use other types of batteries also... DA faQ!?!?! if thats true i will never buy another fenix light again..
I agree. My (Nitecore) is at home, in-light charging any 18650 battery. It shouldn't be necessary to keep the charging mechanism on a 18650 light
so proprietary, that only their own specially-modified battery would be compatible. That's a big turn-off for me, aside from the low output of the light, itself (compared to other Fenix lights in similar price ranges).
For someone too lazy to buy a good 18650 charger, or who doesn't want to be bothered with the extra expense, I suppose this would be a draw; but for me, it's a deal-breaker, insofar as purchasing this particular model.
Don't get me wrong. I am not slamming Fenix. I own ten of their lights (in the E, PD, and TK Series), and I love every one of them. This one just doesn't float my boat, and I would be inclined to wait a while, until they design a version that accepts
standard 18650 batteries, to keep my charging options, open.
So...I'm saying no to the UC40...but I still want a TK75....
On a side note,
when are Fenix going to design their CR123 lights with a working voltage range wide enough to accommodate 16340 batteries, as well? Not everyone likes dumping hundreds of dollars into primary batteries, you know.
Just a thought....
