It sounds like the internal battery to me. Though the charger could be malfunctioning. You could eliminate that if you had another charger lying around to check with.
Also, the polarity is easily seen on the battery pack. Red wire is positive, black is negative. Check and see if it has any corrosion around the battery. This would indicate a leaky battery.
Also, try charging a few cycles if the truck has been stored a long time. You might get lucky and revitalize the battery.
