Belkin residential gateway battery backup unit designed to provide temporary 12V DC power during outages. This type of unit was commonly used in the late 2000s–early 2010s for cable/phone/internet equipment to maintain connectivity during power loss.
Model BU3DC001-12V (Rev B). Rated input 120V AC and output 12V DC up to 3A. Compact, vented enclosure with integrated power cord and output lead.
Indicator lights and front controls include status for AC power, battery testing, low battery, and fault condition. Rear power switch present.
Important: This unit currently shows the “Replace Battery” indicator and will require a new internal battery to function as intended.
The battery is not included due to shipping constraints but I have included a photo for reference..
Good candidate for replacement/repair or for buyers familiar with swapping sealed lead-acid batteries in UPS-style devices.
Please review all photos carefully as they are part of the description.

CONDITION
Pre-owned unit in good physical condition with light cosmetic wear from normal use.
Powers on and indicator lights function. The “Replace Battery” light is illuminated, indicating the internal battery has failed and needs replacement. No further functional testing was performed due to the battery condition.
I do my absolute best to describe conditions honestly and accurately. Function was verified at the time of testing.
The battery is not included due to shipping constraints but I have included a photo for reference..
