Direct 12 V replacement

The BTI RBC11-SLA11-BTI is a sealed lead-acid battery unit built to restore runtime to compatible UPS systems. It delivers a steady 12 V DC output from four internal cells rated at 18 A. The unit weighs 51.88 lbs and has been listed by the manufacturer since January 30, 2020.

Suits single-battery UPS owners

This pack fits users whose UPS requires a single 12 V 18 A SLA module and who want a new, factory-fresh replacement. It does not suit installations that call for a different voltage, a higher amp-hour rating, or a multi-battery string configuration.

Handles standard UPS loads

The 18 A rating supports typical home-office and small-business UPS loads during short outages. Extended runtime demands or higher-wattage equipment will exceed the capacity of a single 12 V 18 A unit.

Questions about this item

Which UPS models accept a 12 V DC, 18 A sealed lead-acid battery unit?

The RBC11-SLA11-BTI fits UPS units designed for a 12 V DC, 18 A SLA battery pack; check your UPS manual for the RBC11 part number before ordering.

Can I mix this 12 V, 18 A pack with older battery modules still installed in the same UPS?

All modules in a UPS string should share the same voltage, capacity and chemistry; replacing the full set avoids imbalance and premature wear.

How do I confirm the new RBC11-SLA11-BTI is delivering the rated 12 V output after installation?

Measure the DC voltage at the battery terminals with a multimeter; a fully charged pack reads approximately 12 V DC under no load.
