By multiplying 2 Amps x 120 Volts, you find out the refrigerator uses 240 Watts. The batteries will need to deliver 20 Amps to run the refrigerator (240 Watts/12 Volts = 20 Amps). Typically, refrigerators operate about 1/3 of the time (1/3 duty cycle), or 8 hours a day.Therefore, the A.H. drain will be 160 A.H.(8 hours x 20 Amps = 160 A.H.). After the load and running time is established, the battery bank size can be calculated.ypically, refrigerators operate about 1/3 of the time (1/3 duty cycle), or 8 hours a day.

91mm Reamer, no sewing-eye. The Reamer is typically used for punching holes in lighter material such as Leather or Canvas, and drilling (or reaming) holes into materials like wood. The tool is tapered so as with any Reamer it can be used to enlarge a whole by twisting and scraping the edges of the opening. The sewing eye can be used to push/pull a heavy thread through Canvas, Nylon, or any material the tool can penetrate. The Sewing Eye was first added to the Reamer in 1985. The Reamer has a hardness rating of RC 52, but it is not known if this applies to all versions if the tool. There are currently three versions of the tool in production. The basic variation is with, or without, a sewing eye. The third is a version included on the Alox scaled knives.
