Questions about this item

Should I pick the 2 x 12V 7Ah cartridge or look for a different capacity?

The RB1270X2C supplies exactly two 12V 7Ah sealed lead-acid cells, matching the original specification for compatible CyberPower UPS units.

What does the 7Ah rating actually give me once the cartridge is installed?

It restores the UPS to its factory runtime so the unit can deliver its rated volt-ampere output during a power outage.

Does the cartridge use a standard F2 terminal or a proprietary connector?

The batteries are sealed lead-acid blocks designed to drop straight into the CST135XLU, CP900AVR and CP1200AVR without adapters.
