Q. What are the minimum testing requirements for batteries in an uninterruptible power supply (UPS)?
A. Maintaining power to the equipment when the electric turns off is a key function of the uninterruptible power supply (UPS). Therefore, battery operations are a key function to be tested in the UPS. Manufacturers typically provide expected battery run times based on the load. These can be used to measure the functionality of the battery. See this graph of the runtime as one example: http://www.apc.com/products/runtimegraph/runtime_graph.cfm?base_sku=SMC1000C&chartSize=large.
While used batteries could be redeployed in UPS equipment if it meets the manufacturer’s run time functionality, it is recommended that the battery in the UPS be replaced with a new battery.
Another way to resell a working UPS is to test the UPS functionality with a known good battery. You can remove the battery after testing and sell the UPS as R2/Ready for Resale as long as the UPS passes functionality tests. Conversely, selling a UPS with an untested or failed battery would put it into the category of R2/Ready for Repair, and subject to all the requirements for downstream due diligence of the buyer to purchase equipment containing Focus Materials.
