Hi, you say the voltage is 3 volts each, then it never work , remember it's requires at least 18 to 20 volts to light up.
if a battery measure's below 10v it's normally impossible to charge again as a lot of chargers will not go below this level, you could try a car battery charger to bring the level up however do this with care and don't leave on charge Regardswww.gewizrepairs.co.uk
