well today i did some tests with old bateries, i was fixing a couple of no breaks and the batteries were dead.. i decided to open it and add 0ppm water to it and see what happen
it happens that the batteries came back to life one better than the other...
in the attempt to charge them i applied overvoltage to it several times..
well i was doing some last tests shorting the battery that was not so good and i noticed that it started to make noise
the battery was also generating hydrogen probably in a shorted cell that was already intriguing me
but than when i shorted the cell i noticed that there was a potential difference build (lika a charged capacitor) 60v on the multimeter and it started to drop til reach 22v
i couldnt repeat the 60v thing... but finaly i got something real strange to happen!!!!
actually two things
i discovered that batteries have a kind of electrostatic potential associated to it.. i have two batteries siting on a insulating wood floor and it shows the sum of the potential of them connecting the multimeter to the oposite sides of it without the connection between the batteries
im not sure but it seems that if my power supply is on the nois is higher even if it is not closing the circuit !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! i may be wrooooong or high
well guys im using 12v 7a batteries just playing around.. i kind of found some electrostatic behavior definitely
i will try more about it
well disconnecting the dc source from line the magic dc disapear =(
