Okay, it came with a nice sheet of safety instructions, but when it got to the LED lights it said look at the device for instructions. I looked at the device instructions, there is pictures, but I'll give a bright, shiny nickel to whoever tells me what they mean. I had it on overnight, red flashing light the whole time. I guess should have meant it is overheated. I pulled out the battery, let the device cool (it was cold to the touch), put the battery back in, it's flashing green. What does that mean? Well yes it's supposed to mean I'm charging now (theoretically) but it was charging all night. BTW, I specifically looked for something that said don't charge overnight, don't charge over 4 hours, whatever. There was no limit given. So, this thing might work, but the instructions should say what the lights mean, how long you should have it plugged in, useful information. I hate to think I'm killing a $50 battery for this charger. I'm going to go ahead and submit this review while I'm still a little ticked off, goodbye.
