Douglas Battery Charger

[redneck power co]

I have a Douglas Battery charger for forklift batteries. The input is Volts 208/240/480  Amps 5.2 4.5 2.3  and the output is 12 Volts and 90 Amps.

My question is does anyone know a way to use the charger in any way for a windmill or anyother kind of power making devices. Or should we just scrap it for the metals.

one more thing the input is AC and the output is DC

Why scrap it? We could always use another charger at work. We have 5 electric lifts.

If you want to sell it, please put in a classified.

If you want to use it with a high voltage windmill or solar pv setup, since it puts out 12v, it could be a stepdown transformer.

  When I built my 4KW wind generator, I used a 4KW AC Alternator. It ran a Variac on one 120V leg, through a Diode, charging one battery bank, and a 36V Golf Car charger on the other 120V leg. Also had an electric heating element hooked across both legs to get the 240V and had it heating a large tank of water. Never had electronics training, so, used my imagination. As the generator got excited, the voltage would be minimal, but, it DID light a 75 watt lamp I had plugged into the system. At full speed, I had 255 volts, and both legs charged nearly even. Lucky, I guess  Never had a bit of trouble with high -low speed on either charger  I'd say use the charger if it's the same DC Voltage as your battery bank. .
