A:

Quick Answer

The advantages of battery-powered pumps include their ability to run when alternating current is not available, easier speed control and greater energy efficiency. Because they do not depend on the power grid, they are more portable than AC pumps.

Adding a battery-powered sump pump to a basement with an existing sump pump provides an extra layer of insurance in case there is a power outage or the AC pump fails. The backup pump also helps in cases where the flooding is more than the standard pump is able to remove.

Speed control is easier with DC motors than with AC ones. When the DC motor is connected to a pump, this allows for easy control of the flow rate to meet the specific needs of a particular application. While it is possible to control the speed with AC pumps, the process requires a separate controller.

The greater energy efficiency of battery-operated pumps ensures longer battery life. Some DC pumps are efficient enough to operate with solar power.

Battery-operated pumps generally do not provide the high speed of AC pumps. When moving large volumes of liquid, they may not be able to provide sufficient pumping power. DC motors also have a shorter lifespan than AC ones do, so owners must purchase replacements more often with these pumps.
