yeah, i'm not too big on the red/green flashing either.. It seems like the longer you leave it on, the faster it blinks (not sure if that means it has more charge that way or not)...
If you don't want to have to take 3 or 4 batteries with you every day, i'd suggest getting 401 batteries (i just ordered some backups from Ruyan (stainless/chrome), 10 bucks each, and they work great. I can get a whole day off of one batt, always have another on charge at home, usually only really need 1.5 batteries for a whole 24 hours, but only need one actually on my person. Definitely will want the larger battery, the one you have is 100mAh,, the 401 is 200, should last almos twice as long..
