My UPS has failed. I've tried replacing the battery without success. The failed one was 700VA. The UPS is for home use: a single PC and three screens (see sig). I want battery backup and surge protection. I would prefer the UPS to be inline. I don't expect extended use - just enough to finish whatever I'm doing and shut down cleanly and to cover momentary power outages. It's likely going to be situated somewhere near my feet if it can't be hung from my desk, so some ruggedness would be appreciated.
