You must determine your power requirement and compare that to the APC tech specs. With a new fully charged battery, 50 watts can be maintained for about an hour and 100 watts can be delivered for nearly 30 minutes. A 390 watt load (a typical pc) can be maintained for about 3 minutes according to the APC 650 runtime graph published here: https://www.apc.com/products/runtimegraph/runtime_graph.cfm?base_sku=BE650G1&chartSize=large A new battery should perform well for up to 2 years but will loose performance as it nears end-of-life which can be as long as 5 years. After that period, the ups becomes a nice surge protector until you replace the battery with the recommended unit as stated in the APC specs. A larger load will require a larger ups with correspondingly larger battery supply.
Sorry, there was a problem. Please try again later.Depends on the power draw - how many watts is the system pulling? See this runtime chart for expected uptime under various loads: https://www.apc.com/products/runtime_for_extendedruntime.cfm?upsfamily=29&ISOCountryCode=us
Sorry, there was a problem. Please try again later.Thank you for your inquiry. It would all depend on how much power the device draws pulls. At 195 watts the unit would provide 10 minutes of runtime. At 390 watts of power the device would provide 3 minutes of runtime. If the equipment draws less than this then the runtime will be more.
