RBC43 vs APCRBC105 Key Specs
Physical Dimensions
The RBC43-UPC measures 21 inches in length, 8.5 inches in width, and 3 inches in height. It has a compact, flat profile suitable for specific rack spaces. The APCRBC105-UPC is slightly longer at 22.5 inches and wider at 4.8 inches, with a height of 7.5 inches. The APCRBC105 is taller and deeper, while the RBC43 is flatter. You need to check your rack clearance carefully. The RBC43 offers a lower height, which may fit tighter spaces better. The APCRBC105 has a different footprint that suits the Smart-UPS XL series. Size matters for installation fit.
Weight
Weight is a critical factor for rack stability and handling during installation. The APCRBC105-UPC specification lists a weight of 52 pounds. This indicates a substantial mass typical for high-capacity lead-acid batteries. The RBC43-UPC data does not list a specific weight value. Without this number, you cannot directly compare the heft of the two units. The APCRBC105 is confirmed to be heavy. You should ensure your rack can support this load. The RBC43 might be lighter, but the data is missing. Always verify rack load limits before mounting.
Compatibility
Compatibility determines which UPS systems you can use. The RBC43-UPC fits models like the SMT2200RM2U, SUA3000RM2U, and SUM3000RMXL2U. These are often Smart-UPS or Smart-UPS RT series. The APCRBC105-UPC is engineered specifically for the Smart-UPS XL series, including SUA2200RMXL3U and SUA3000RMXL3U. The model numbers differ significantly. You must match the battery to your specific UPS model. Using the wrong battery can cause errors. The RBC43 suits standard rack units. The APCRBC105 is for the XL line. Check your UPS label first.
Capacity
Capacity affects how long your equipment stays running. The RBC43-UPC provides 480 VAh of backup power. This is a specific energy rating for its voltage and cell configuration. The APCRBC105-UPC is described as a 48V maintenance-free sealed lead-acid battery pack. It does not list a VAh or Ah rating in the provided data. The RBC43 has a clear capacity number. The APCRBC105 relies on the 48V system voltage. You need to compare VAh or Ah for true runtime. The RBC43 offers more transparent capacity data.
Warranty
Warranty coverage protects your investment. The RBC43-UPC comes with a 2-Year warranty. This is a standard period for replacement batteries. The APCRBC105-UPC includes a full 18-month warranty. The RBC43 offers longer coverage by six months. Both are backed by the same brand. A longer warranty reduces risk if the battery fails early. The RBC43 provides two full years of protection.
