Eaton RBC36-SLT – 36VDC Replacement Battery Cartridge

Product Overview

The Eaton RBC36-SLT is a pre-assembled 36VDC UPS battery replacement built for select SLT-series UPS systems, including the SMART1500SLT and SMX1500SLT. It is the correct part for a commercial UPS battery backup installation where the internal three-battery cartridge in an SLT UPS has weakened or reached end of service life. Facilities and AV integration teams use the RBC36-SLT to restore rated runtime on rack-mount or tower SLT UPS units supporting network equipment, AV racks, and other line-interactive protected loads without replacing the entire UPS.

Product Description

The RBC36-SLT replaces the internal three-battery cartridge used in select SLT-series UPS systems, specifically the SMART1500SLT and SMX1500SLT models built with a pre-assembled three-battery cartridge. Each cartridge contains three 12V 9Ah sealed lead-acid batteries, screened and certified to meet or exceed the original SLT UPS manufacturer specification, so a commercial UPS battery backup installation performs the same as it did when the UPS was new. The maintenance-free, spill-proof construction is suitable for enclosed AV racks and data closets where ventilation is limited and where a leaking battery could damage nearby rack-mount equipment. Because the cartridge ships pre-wired, replacement in a facilities or AV rack setting typically requires no more than removing the old cartridge and connecting the new one through the existing harness. Reusable shipping packaging allows the depleted battery cartridge to be returned to a recycling center in compliance with lead-acid battery disposal regulations. Before ordering, confirm your SLT UPS model has the pre-assembled three-battery cartridge configuration, since earlier SLT UPS versions may use individual battery packs instead.

Technical Specifications

Frequently Asked Questions

How do I know if my SLT UPS uses the RBC36-SLT cartridge?

Confirm the UPS model is SMART1500SLT or SMX1500SLT and that it uses the pre-assembled three-battery cartridge configuration rather than individual battery packs before ordering.

Can I install the RBC36-SLT myself in an AV rack or data closet?

Yes, the cartridge is pre-wired and connects through the UPS's existing battery harness, making it a straightforward swap for facilities staff or AV technicians without specialized tools.

Does replacing the battery cartridge affect the UPS's runtime rating?

No, the RBC36-SLT is certified to meet or exceed the original battery specification, so runtime should return to the UPS's factory-rated performance once the new cartridge is installed.

What is the expected service life of the RBC36-SLT?

Typical service life is 3 to 5 years, depending on ambient temperature and discharge frequency, which can vary in warmer AV racks or data closets.

What warranty applies to the RBC36-SLT?

The cartridge carries an 18-month limited warranty for U.S. and Canada purchases, independent of the warranty on the UPS unit itself.

Can Creation Networks help verify compatibility before I order?

Yes, contact Creation Networks with your SLT UPS model and serial number and our team can confirm whether the RBC36-SLT is the correct replacement cartridge for your system.
