I took the caps off the cells and am not sure if they are filled to the correct level. There was liquid visible but when I took a piece of wood and stuck it down there to check the level it was only about an eight inch deep. This may be alright though as this may just be the top of the lead and copper plates. Anyone know anything about the fill level?


Recently in the 300SD the starter failed. I replaced it and now Im having this battery problem which leads me to expect that the previous dying starter was drawing a huge amount of current thus destroying the battery. It has enough CA to start a car so I put it in the young car to see if I can bring it back to life (easier car to start and probably a better charging system)
