Cool, I'm glad I asked. This works for a tank coil as well? I've been told that a tank coil presents no loss and creates no heat.
if u need 1 mh aircore you will have to do handreds of turns ...
i made 1 mh inductance with ferrite toroid core got from old ATX power supply ( i though its AL=92 ) .. with only 114 turn about 4 meters from 0.7mm wire diameter ...

You have to mind your saturation though if you are using a core. For the desulfator, the L3 inductor, its keeping the pulses/ringing of the desulfator from affecting the charger. So it needs to maintain its inductance under the full charge current. The ATX one will work fine for smaller charge currents, but an air core will work fine until you burn the insulation.
Also, if you want to buy instead of make, parts-express sells air-core inductors for decent prices. Meant for crossovers in stereos
