Direct Replacement Cartridge

The Battery Technology Inc. RBC18-SLA18-BTI is a new replacement battery cartridge numbered 18 for compatible UPS units. It restores backup runtime when the original cells reach end of life. The unit is ready for installation in supported systems.

Verify Compatibility First

Confirm that your UPS model lists cartridge #18 as the correct replacement before ordering. Check the manufacture date on your existing unit against the 2014 listing date to help identify the correct revision. Ensure the physical bay and connector layout match the original cartridge.

For UPS Maintenance Only

This cartridge suits administrators maintaining specific UPS models that require the #18 form factor. It is not for buyers needing a complete uninterruptible power supply, additional outlet count, or network management features. Builders looking for whole-system power protection should evaluate full UPS appliances instead.

Questions about this item

What comes inside the RBC18-SLA18-BTI cartridge and what must I supply separately?

The sealed lead-acid cartridge is a complete drop-in module for compatible APC Smart-UPS units; no extra cells or cables are required.

How do I know this #18 cartridge is the correct version for my UPS?

Match the RBC18 part number printed on your existing battery or listed in the UPS manual; the #18 designation identifies this exact cartridge.

What does the 2014 first-listed date tell me about real-world performance?

It marks when BTI introduced this replacement cartridge; actual runtime depends on the UPS model and load, not the listing date.
