Using just the 6volt battery

[Guest guest]

You can, but you should not put metal onto the body. Instead, cover the

springs with bits of cloth, cotton balls, etc wetted, and use it for

local things like bites, warts, etc. Not useful for more systemic

problem microbes, but handy in a pinch. Do not do this with any

voltage larger than 6 volts..like 9volts could kill you. 6 volts

should be safe, but 4 volts will also work if it's a child, etc with

less skin effects.
