Oooh!!! I have a battery question. Not sure if this has been addressed yet or not. Sorry if it has, but it's a quick one.
Just got my MF and I'm pretty sure it was fully charged when I got it (not really sure, my husband stole and and has claimed it as his own since it got here). I'm charging it for the first time and the LED stays on the entire time. It's an auto, not sure if Bloog even has manual batts. But I'm kind of concerned about it. I felt it and it's not hot or anything but the light stays on the entire time it's charging. I haven't fully charged it yet so I'm not even sure if it's charging or not.
I do have to admit that it's not a charger purchased from Bloog.
Is this normal?

Yes that's normal. When I use the Bloog charger, the battery light comes on and stays on until it is finished charging, then the light goes out on the battery. The charger itself goes from red to green.
When I use the V4L USB charger, the bat light comes on and stays on, and when it's done, the bat light just dims, never goes completely out.
The battery was partially charged when you got it, maybe 75% or more.

Speak English man! LOL, so like 320mah = 3.2 hours to charge? or something?

Errr, no.
Depends on the C rating of the battery and on the output current (A) of the charger.

Actually, it's even less linear that that since Lithium bat chargers are supposed to be smart and have 2 charging phases with different characteristics: one up to 80% battery charge in which they supply a constant charging current, and a different charging mode after that.

Was it something I said?
I figured as much, but I think I've mentioned before, my knowledge of electronics is limited to plumbing analogies. Once the pipes disappear into little black boxes I have no faith I will ever understand what wizardry goes on inside! And since as you pointed out before, the "smartness" is in the usb part of the charger, the A of the charger may well be irrelevant if it's being "smarted" by the circuitry in the usb part, right?

Just not the only thing that matters.
It's still important, because a 500mA charger will limit what it can supply to half of what a 1A one will, even though it's not the only factor in the game.
(500mA is lower than what a good bat can take while charging.)

I wonder if that's why, for the last bit of charging, the light on my Bloog USB charger is both red and blue (making it purple)....

yessss, I get that on the riv4l usb too. I used to think it was done charging, but the batt tip was still bright. Only when it dims do I know it's done now (it never goes out when on the riv4l usb, but does go out on the bloog one, weird huh?)
