what is the minimum voltage that a 6v battery must have before the charger can use its repair function?

The minimum voltage is 4.2 V. If it falls below 4.2, your battery may be damaged. Usually available for cars and motorbikes, please refer to the product description.

Directions say charger is for lead acid batteries, and the website says for agm batteries. need to verify if this unit designed for agm useage?

As long as it is 12V it will work

Is it plugged into a 110 volts or a220 volts AC?

I've never tried it on a 220 outlet and not sure that I would. Works fine on 110. It's a good little product.
