According to the US Department of Energy, the average refrigerator uses about 725 watts of electricity and 15 to 20 amps, which is about 10 percent or more of your electricity bill. How many amps does a Whirlpool fridge draw? … Continue reading →

When installing a residential refrigerator most RV manufacturers will come stock with four 6-volt batteries with 400 amp hours and 200 “usable” amp hours (because you should only drain standard lead acid batteries to 50%). Dealers and salespeople have told … Continue reading →

It is estimated that, by 2018, over 1.6 million tonnes of silver had been physically mined throughout history. All this metal would fit in a cube 55 meters on each side. Now at 1.74 million metric tons, that would be … Continue reading →

Silver did not fare so well during stock market crashes. However, you’ll see that silver fell less than the S&P in all but one crash. This is significant because silver’s high volatility would normally cause it to fall more. What … Continue reading →

For example, 50.59 feet of 12-gauge wire weighs one pound, and 80.44 feet of 14-gauge wire weighs one pound of bright #1 copper after it is stripped. How much is a pound of copper wire? Copper Copper Price/lb. Bare Bright … Continue reading →

This means that it does not change over time. Cells and batteries supply direct current ( ). This means that in a circuit with an energy supply from a cell or battery, the current is always in the same direction … Continue reading →

Duracell has been well known for decades with batteries in every shape and size. This 4-pack of batteries is affordable even for folks on a budget, and are guaranteed to be usable for seven years. Which battery brands last the … Continue reading →

Common nominal pack voltages in current vehicles range from 100V-200V for hybrid/plug-in hybrid vehicles and 400V to 800V and higher for electric-only vehicles. The reason for this is higher voltages allow more power to be transferred with less loss over … Continue reading →

A battery, or cell, is composed of a cathode, an anode and the electrolyte. A chemical reaction takes place within the cell, moving electrons from one place to another and producing an electric current. Half of the cell contains electrolyte … Continue reading →

The feedstocks used in the production of lithium-ion batteries are in the form of metal salts, predominantly sulfates. The sulfates for cobalt, nickel and manganese are combined in various ratios depending on the chemistry type to form the precursor cathode … Continue reading →
