Question about Drills
Can I overcharge the batteries ?? How do I know when the battery is charged ??
You cannot over charge a battery pack as the charger stops at full charge. However by recharging a partially used battery pack you can develop a memory in the pack that the charger will not charge past

your NG3 should have been preprogrammed for the type of batteries you are charging. The NG3 has the 3 wires from the power cord. Here is what I have done:
Brown from charger goes to black wire
Blue goes to white wire
yellow green goes to green ground.

If you have tried discharging the batteries prior to charging them already with no result and from what you describe in your post, then I would have to say the charger has issues. Go to HD or Lowes (not sure if Lowes carry Makita) but another charger and test your battery again. If you get the same fault, there is an issue other than the charger, if not you need a new charger anyway. If you get the same fault with the new charger, you can always return the new one. Short of opening up the charger and using a volt meter, this is the easiest way to test to pinpoint the real problem. I hope this helps and good luck!

About the only indication if the charger is not working is when you put the batteries into the charger and no lights come on. This indicated that the charger is faulty. If the lights come on it is most likely the batteries. The best thing to do is take the batteries and charger to a Bosch service center and they will test them for you. Most will do this for free.
