• it varies directly depending on the draw of power you have hooked to the battery.... typically with just a pc and a small flat panel screen 20-35 minutes.... about long enough to save and shut down safely

• Thank you for your inquiry. The amount of runtime the BN450M can provide depends on the size of the load attached. Please refer to the attached brochure for estimated runtimes for typical loads. http://www.apc.com/salestools/JSIE-AD7S69/JSIE-AD7S69_R0_EN.pdf
