Might be worth it, because I have had such a problem with my battery and doing that just ONCE has improved the battery life a considerable bit.

But if that doesn't work, then look into the warranty thing. Just be sure to try everything
The highlight there is mine.

If the light on the charger is blinking then the charger is in "fault state". The most likely cause of the problem is the way the battery is positioned in the charger, which confuses the charger because it doesn't know if it has to charge the 9.6v transmitter or the 7.2v robot battery.

To fix the problem, unplug the battery, and take it out of the charger. On the bottom of the battery slots on the charger there are little buttons that are depressed when the 7.2v battery is in there. If you try charging a 7.2v battery and the battery is not properly in the slot, then the charger will freak out and give you the blinking LED fault state.

To fix this, always make sure you make sure the battery is fully seated in the battery holder, and then plug it into the connector directly in front of the battery. If you do this, you will never see the blinking LED again (fault state), and your batteries will charge fine.
