APC RBC34 Compatible Kit

This replacement battery kit provides four 6V9A sealed lead-acid cells configured for APC RBC34 UPS cartridges. It restores runtime for compatible Smart-UPS and Back-UPS units when the original batteries reach end of life. The pack arrives factory fresh and includes step-by-step installation instructions for a straightforward swap.

Sustained Discharge Performance

The high-rate discharge chemistry is engineered to maintain voltage under the continuous loads typical of UPS operation during extended outages. Each 6V9A cell delivers consistent current without the voltage sag seen in general-purpose SLA batteries. Factory-fresh stock ensures the pack starts at full rated capacity rather than degraded shelf life.

Four-Cell 6V9A Configuration

The kit contains exactly four 6V9A batteries wired to match the original RBC34 cartridge layout. Installers must verify their UPS model accepts this specific cell count and voltage arrangement before purchase. Builders needing a different cell quantity or voltage rating will require an alternative kit.

Questions about this item

How much heat does the 6V9A battery kit generate during continuous operation?

The four sealed lead-acid cells produce minimal heat under normal float charge; ensure the UPS ventilation slots stay clear.

Which APC UPS models accept the RBC34 compatible kit?

The kit fits APC UPS units designed for the RBC34 cartridge; verify your UPS model against the APC compatibility list before installing.

Will the RBC34 kit work in an older APC Smart-UPS that originally shipped with an RBC2 cartridge?

No, the RBC34 uses four 6V9A blocks wired differently from the RBC2 form factor; using it in an incompatible chassis risks damage.
