Ball Machine Selector 2005 — Power Supply

Runs on Battery or Power Cord. An “X” in this column means that you can power the machine with a battery or a power cord plugged into an electrical outlet.

Runs on Power Cord Only. Machines in this column require an electrical outlet for power.

Runs on Battery Only. These machines can only be powered by a rechargeable battery.

Battery Amp/Hour. This is an indication of how much “juice there is in the batteries.” It is a measure of the number of amps of electricity the battery can deliver in 1 hour. One manufacturer described amp/hours as being like a car’s gas tank. More amp/hours is like a bigger gas tank, meaning that the machine can run longer on a charge. We are publishing this number instead of the machine’s battery-life. We felt publishing this number for each machine helps reduce any discrepancies in the battery life that is indicated by each of the manufacturers.

Battery Life Indicator. These machines have some sort of indicator to let you know how much battery life is left. Once again, some of these indicators are more informative than others. Talk with the manufacturer for a more detailed description of how it works.

Battery Swapability. An “X” in this column means that the machine allows you to take out a battery that is almost out of juice and replace it with a fresh battery. However, keep in mind that to do this you will have to purchase a spare battery.
