Replacement Cartridge for SMX UPS

The PowerWarehouse APCRBC115-PW replaces Battery Cartridge #115 in APC SMX1500RM2U, SMX1500RMI2U and SMX48RMBP2U series units. It is built for IT managers maintaining rack-mounted UPS systems in server rooms or network closets. The sealed lead-acid design fits the original chassis without modification.

Sustained backup performance

The maintenance-free cells deliver consistent voltage during extended outages rather than only brief rides through brownouts. Leak-proof construction prevents electrolyte migration when the UPS operates continuously at high ambient temperatures. An eighteen-month warranty reflects the expected cycle life under normal float-charge conditions.

Rack-mount form factor

Dimensions of 16.94" L x 6.19" W x 3.00" H match the OEM cartridge bay exactly, so the unit slides into 2U rails without cable re-routing. At 26 LB the cartridge requires two-person handling or a lift tray during installation. Terminal layout mirrors the original, preserving hot-swap capability for zero-downtime replacement.

Questions about this item

How much heat does the 26 LB sealed lead-acid cartridge add to an SMX1500RM2U running continuously?

The maintenance-free sealed lead-acid design is leak-proof and generates typical UPS battery warmth; the 16.94" x 6.19" x 3.00" cartridge fits the SMX1500RM2U bay without extra cooling.

What must already be in the rack for the APCRBC115-PW to work?

A compatible APC Smart-UPS such as the SMX1500RM2U, SMX1500RMI2U or SMX48RMBP2U with an empty Battery Cartridge #115 slot.

Will the 18-month warranty cartridge fit alongside an older RBC115 still in the same SMX1500RMUS?

Yes, it replaces APCRBC115 and RBC115 directly, so it slides into the same bay without modification.
