UPC RBC2 vs RBC114 Specs

Physical dimensions

Edge: Tie

The UPC RBC2 measures 5.94 inches in length, 3.7 inches in width, and 2.52 inches in height. The APC RBC114 replacement battery is 5.94 inches long, 2.01 inches wide, and 3.90 inches high. Both units share the same length, which helps them fit similar footprints in their respective UPS chassis. However, the RBC2 is significantly wider but shorter. The RBC114 is narrower but taller. You need to check the internal space of your specific APC model, as the height difference may affect clearance or stacking within the unit. The width difference is also critical for terminal access.

Weight and mass

Edge: UPC RBC2 Small UPS Battery

Weight can indicate the amount of lead-acid material inside the sealed case. The UPC RBC2 battery weighs 5.5 pounds. The APC RBC114 replacement battery is lighter, weighing only 4.28 pounds. This is a difference of 1.22 pounds. A heavier battery often suggests a larger plate surface area or more electrolyte volume, which can correlate with higher capacity or longer cycle life. The RBC2 is the heavier unit in this comparison. If you are installing the battery in a location where weight distribution matters, the RBC114 is the lighter option. The RBC2 provides more mass per unit of volume compared to the RBC114.

Terminal type

Edge: UPC APC RBC114 Replacement Battery

Connector compatibility is vital for a direct replacement. The data for the APC RBC114 explicitly states it uses T2 terminals. This ensures it plugs directly into APC Back-UPS NS Network 40 BN4001 and BE450G models without adapter issues. The specifications for the UPC RBC2 do not list a terminal type. You must verify that the RBC2 uses the correct connector for your BK300, BK500, or SC420 models. If your UPS requires a T2 terminal, the RBC114 is the confirmed choice. For other APC models, the RBC2 is designed for compatibility, but the terminal specification is not provided in the data, so you should inspect the existing battery or the UPS manual to confirm the pin layout matches.

Installation features

Edge: UPC APC RBC114 Replacement Battery

Ease of installation varies between these two replacement batteries. The APC RBC114 description highlights that it is plug-and-play and hot-swappable compatible. It also comes with all required connectors, cables, fuses, and metal enclosures where applicable, meaning no assembly is required. The UPC RBC2 is described as pre-charged and ready for immediate use. It is a maintenance-free sealed lead-acid battery. However, the RBC2 data does not mention included cables, fuses, or enclosures. If your UPS model requires additional wiring or mounting hardware, the RBC114 appears more complete. The RBC2 may require you to reuse existing components or purchase them separately, depending on the host UPS model.

Warranty coverage

Edge: UPC APC RBC114 Replacement Battery

Product protection is an important factor for replacement batteries. The APC RBC114 replacement battery includes a 2-year warranty on all UPC-branded products. This provides a defined period for coverage against defects. The specifications and features for the UPC RBC2 do not mention any warranty period. You do not know if the RBC2 comes with a 1-year, 2-year, or no warranty based on the provided data. If warranty support is a priority for your purchase, the RBC114 offers a clear, stated benefit. The RBC2 may have a warranty, but it is not listed, so you cannot rely on it for comparison. The RBC114 is the safer choice for guaranteed coverage.
