APC RBC18 Compatible Battery Kit

This factory-fresh replacement battery kit matches the APC RBC18 specification and contains two 6V9A sealed lead-acid cells. It is designed for administrators who need to restore runtime to a compatible Smart-UPS unit without waiting for an original cartridge. The kit arrives new and ready for immediate installation.

Two 6V9A Cells Restore Runtime

The bundled pair of 6V9A batteries replaces the original cartridge in a single step, returning the UPS to its rated backup capacity. No additional cables, mounting hardware or configuration software are included, so installers should reuse existing connections and follow the UPS manufacturer's replacement procedure. Buyers who require extended runtime beyond the standard cartridge rating or a different voltage configuration will need a separate solution.

Questions about this item

How often will the two 6 V 9 Ah batteries in this RBC18-compatible kit need replacing?

Typical service life is three to five years; plan to swap the pair when runtime drops noticeably or the UPS signals a battery fault.

What limits continuous runtime when the UPS runs on this battery kit?

The 9 Ah capacity of each 6 V cell sets the energy ceiling; sustained loads will drain the pack until the UPS reaches its low-voltage cutoff.
