Questions about this item

What does the 12V rating mean once the battery is installed in the Back-UPS 400?

The 12V rating matches the UPS input so the unit can charge and discharge the cell correctly, delivering the runtime the Back-UPS 400 was designed for.

What interface does the battery use and what does it limit?

The battery connects with standard F2 faston tabs; this mechanical interface limits use to UPS models that accept the same tab spacing and 12V chemistry.
