Q: 6. I'm not sure that my charger is working correctly. The directions say a red light should come on when it is plugged in. I didn't see a red light. No lights were on when it was plugged in. My batteries were left in the charger for 9 hours and the green light never came on. I tried one of the batteries and it had power. But that doesn't mean it didn't have a partial charge straight out of the package. Should a light be on when it's charging?

A: I dont have any charger like that but I had a similar experience with a battery charger for a Milwaukee electric munual cutter. The charger didnt startcause I plug it with the battery on. So I had to plug it alone first and anything happened, until I place the battery as indicated in the battery holder, after that a red light appeared, it turned Green thirty minutes later to show battery was fully charge, and its the way the God damn thing Works. I suggest that person to experiment before calling the dealer..
