To help explain the energy savings of Panasonic's Assembly Tools we've created an example to show how much a manufacturer could save by using cordless assembly tools.
A manufacturer puts together 60 parts per hour and each part requires 2 fasteners. They are running 2 shifts, 8 hours each, 5 days a week and with two weeks of shutdown.

Energy Cost to charge the battery
To calculate the yearly cost of running a cordless tool we add costs to charge the battery and to leave the charger plugged into the wall outlet.
3 Charge Cycles Per Day x 250 Days Per Year = 750 Charge Cycles
Use this example in your plant, look around and estimate the number of tools in the plant then multiply that number by $8.40. Example (20 Tools x $8.40 /yr. = $168.00 /yr. to run cordless tools).
If your plant converted 20 tools your company would only spend $168.00 per year in electrical cost!
In comparison, using the same example an air tool uses $505.01 annually in energy costs. There is a potential savings of $496.61 annually per tool.
