Your BR900MI UPS is running on fumes. The battery's degraded, runtime's dropped, and the next brownout takes your switch or router down with it. This is the exact cartridge APC built for that unit. Pull the old one out, slot this in, close the lid. No cross-referencing part numbers at 7am before a client call. Sorted
