Charging Batteries from Batteries part 2. Free Energy?

 Dandman, you are correct that there is no real accurate way to check amps in a battery becuase the load test actually takes amps away as does anything used to check the ampreage. You also need to know that transferring travels through resistance and resistance takes away amps. The voltage change you are expiriencing is not a gain, it is still a loss but the loss is by way of the amps. Just becuase you show 12 volts at the start and 12.6 volts or higher in the end, doesn't mean you have a gain, you still need to know how many amps are present at the 12 volt start and at the 12.6 volt end. 12 x 500 amps = 6000 watts and 12.6 x 470 = 5875 watts which shows that it may show 12 volts at the start and 12.6 volts at the end but there is still a loss of 125 watts.

Thanks Nightlife, understand that. Also understand the relationship between surface voltage and floating which is why as far as Im aware the old fashioned diesel electric submariners way, using hydrometer specific gravitiy readings and converting them is the only accurate way to know whether you have lost energy in a battery (lead acid)

Question. If a battery charger forces energy the wrong way into a battery to charge it. Is the equalization that appears to happen when you put two different strength batteries to equalize in energy or voltage or both. If both, how?.

Update, I think I know what is going on. The energy being used is being stored and returned to the discharged batteries in the conventional charging style. So far Ive used bulbs across it, inductive motors and even charged another battery across it and every time the batteries return to the same state of charge. This is doing my head in...... Ill be back

Wow its gone quiet in here. Anyone "killed" their good batteries yet?
