I have a Electromagnet with a 96 volt battery pack. it is actually made up of 80 c cell batteries welded together.
how can i recharge the pack without the original charger?????
not easily.
if you have a variac, use it with a 6 amp diode in series.
the cathode will go to the positive side of the battery pack.
slowly turn up the variac til you get a reading of about 96 volts DC on a digital meter across the battery pack. "quickly" touch the diode case and see if it's very hot - if so turn the variac down.
when the diode temp is at ambient, slowly increase the voltage by 1 or 2 volts at a time - checking the temp of the diode.
proceed to increase the voltage to about 105 volts DC.
another alternative is to get a 240 ohm resistor, at least 50 watts and connect the AC line in series with the 6 amp diode and the 240 ohm resistor.
again watch the voltage - when the battery pack has about 105 volts DC across it, it should be almost fully charged.
