Questions about this item

What does the 12 V rating mean when the cartridge is installed in my APC Back UPS Pro BP280S?

The 12 V rating matches the voltage the UPS expects, so the cartridge supplies the correct DC potential for the inverter and charging circuit without any adjustment.

How does the cartridge's connection standard limit what the UPS can draw in practice?

The cartridge plugs into the UPS's proprietary battery port, which caps the available current to the unit's designed load profile and prevents higher draw than the original specification allows.
