PowerWarehouse LEADACIDSLA109-03 replacement

This maintenance-free lead-acid battery replaces the RBC109 cartridge used in the APC BX1300LCD-CN uninterruptible power supply. It restores backup power for servers, networking gear and workstations that rely on that specific UPS model. The sealed design allows installation in standard battery compartments without special handling. Buyers who need a different cartridge number or a higher-capacity pack should look elsewhere.

Sustained discharge behaviour

During a prolonged mains outage the cell chemistry delivers a steady voltage curve until the UPS initiates its low-battery shutdown. Internal resistance remains stable across the discharge cycle, so the connected load sees consistent runtime without sudden voltage sag. The sealed construction prevents electrolyte loss during extended float charging, keeping the pack ready for the next event. Users who require hot-swappable modules or lithium-based chemistry will not find those features here.

Questions about this item

How much heat or noise does the LEADACIDSLA109-03 produce when running continuously in a UPS?

The sealed lead-acid design is maintenance-free and has no moving parts, so it generates no fan noise and minimal heat during normal float charging or discharge cycles.

What existing hardware must I already own for this replacement cartridge to work?

It is built as a direct replacement for the APC RBC109 cartridge used in the BX1300LCD-CN UPS, so you need that specific UPS model installed.
