I use Epsom salt try to rejuvenate, no water, for Razor E100 electric scooter, 12 volts 4.5AH, totally dead, battery.
I filled it with Epson solution and I tried to charge it up with 247.4 volt DC voltage still nothing happened so I changed the polarity of the battery then it works up to 5A charging current.
My question is can the battery be used as reverse voltage, I mean black terminal is +12v and red terminal is ground?
