APC Back-UPS Pro 1500VA Uninterruptible Power Supply (UPS) that worked great up until I moved a few years ago and unfortunately, the battery cover broke in the move. Which is why it’s missing in the photos. The battery is also DEAD DEAD, since she's been off for a hot minute.so the until won’t have a battery with it, but replacements can be purchased online/etc. Good opportunity to get an APC unit for a good price.
