  • Longer runtime with 9.0 Ah capacity upgrade
  • Fits over 100 APC UPS models including Back-UPS and Smart-UPS

Right UPS replacement

This 12 V 9.0 Ah sealed AGM battery kit replaces the APC RBC5 cartridge in compatible Back-UPS and Back-UPS Pro units. It is built for administrators who need a drop-in power source that restores runtime without re-cabling the rack or tower chassis.

Capacity increase over original

The kit raises capacity from the 7 Ah or 7.5 Ah cells originally fitted to 9.0 Ah using the same T1/T2 terminals and case footprint. That extra amp-hour reserve extends battery-backed runtime for the connected load.

Maintenance-free operation

AGM chemistry eliminates watering and venting requirements during its 4 to 7 year design life. The sealed construction produces no gas under normal float charge so heat and acoustic output stay negligible inside the UPS enclosure.

Questions about this item

What does the 9.0 Ah rating mean for my UPS runtime?

The 9.0 Ah capacity exceeds the original 7 Ah or 7.5 Ah cells, so the UPS can sustain its load longer during an outage.

What terminal type does the kit use and will it connect to my APC unit?

The batteries ship with T1/T2 terminals that match the spade connectors on the listed APC Back-UPS and Smart-UPS models.

Will the 5.94 × 2.56 × 3.66 inch pack fit inside my APC Back-UPS 500?

Yes, those dimensions are a direct fit for the battery compartment of the Back-UPS 500 and the other compatible models listed.
