Question

The coil wire has to heat up a min.40 and max.70 degrees. I would like to use a rechargeable AC/DC battery that between 12 to 18 volts. But I hear there are green batteries now. Are they rechargeable, exspencive and better to use in this case? What would be better to use rechargeable or single cell battery? What would be the least expensive? Thak you
