Battery Eliminator


Model:

Description: battery eliminator is any device which provides power to a circuit, replacing the need or use of batteries. A battery eliminator, just as the name states, eliminates the need to use batteries to power a circuit. It is any device which provides power to a circuit, replacing batteries. A battery eliminator can be any number of devices, such as a DC power supply, a 9V wall wart, etc. to power an electronic devices, instead of using batteries. As an example, let's take a nintendo gameboy, a device which ordinarily needs 4 AA batties in order to be powered on. The 4 AA batteries add up to 6 volts DC, since each battery contains 1.5 volts. Since they are connected in series, they add up. This is why it's 6 volts in total. Say if we decide not to put in batteries into the battery slot. Instead, we power it through a DC power supply. We turn the voltage on the power supply to 6VDC and we connect it appropriately to the battery slot, so that the positive terminal of the DC power supply goes to the positive battery terminal and the negative terminal of the power supply goes to the negative terminal of the battery. If we power the game boy this way, through the DC power supply, the power supply acts as a battery eliminator, because it bypasses the need for us to power the gameboy through batteries. This is what a battery eliminator is, any device which can power electronics without the use of batteries.
