RE: С4 beep low batery
Put in 6 x AA rechargeable batteries (1700-2300mAh) , and leave to charge for 14 hours. Once this is complete, you should see the battery outline become solid, and C4 read more stable voltage from car.

After this extended calibration cycle, next charge cycle will not take as long. But make sure not to let battery totally die otherwise you will need to do 14 hour charge again.

If this does not work, use it without batteries. If it still reads wrong voltage with no batteries unit is faulty.

I was the same symptoms as your case.
I also attempted to many things. However, this did not take care of the symptoms. In the end, I was sent to a place where purchases.
After this fixed, symptoms disappeared.
This is just my experience. Take care.
