I've been trying to heal my son with a clear quartz general balance crystal.

The problem is the battery clamps are too big and my son gets electrocuted by the car battery and cries even more.

Can I sufficiently power the crystal with lower voltage? Let's say a 9v battery instead of a truck battery?

Also are there more efficient crystals to heal my sons spreading sores? I heard good things about ruby's vitality energy.

Please help the sores get worse by the day and I fear the government will take him away again if I do not succeed.
