Can someone tell me how to know when a 520 battery is fully charged? My usb plug in has an LED that is red and green. Usually it is red when I first plug in the battery, then after a while it will change to green then back to red/back to green. Is this indicating it is charged or that it is insecure and does not know how to make up it's mind?:blush:

Usually, mine will flicker red/green sporadically when it's almost done charging, then it eventually goes to full green and that's how I know it's done.

Ok, thanks, I guess I just got a couple of insecure batteries. Maybe their mommies did not love them or something? They will not stay green. The longer I leave them in the charger the longer the green light will stay on but then it goes back to red? Oh well. Onward

If you are charging them on a PC then I recommend getting a 4-port 2amp USB to AC charger - I have one at home and one at work.
Newegg.com - Rosewill 2 Amp 4 Port USB International Traveling Wall Charger RUC-6181 for iPhone/iPod/iPad/MP3

It also has enough amps to run a PT but you should remove all of the battery chargers since some PTs need a full 2 amps

The first couple of times I charged them on my computer then I realized I had two USB ports on my power strip on my desk. Duh factor at work for me. ha

We all have "duh factors"...like wondering why my PT isn't working while driving home from work yesterday. It really helps if it's actually plugged in. There's my "duh" factor!
