Capacity and Compatibility Comparison
Capacity and Runtime
Product A offers a 7.2Ah capacity, while Product B provides 9Ah. Both units operate at 24V using sealed lead-acid chemistry. The higher amp-hour rating in Product B suggests it can store more energy, potentially extending backup time for connected devices. This difference matters if you need longer runtimes during outages. Product A’s 7.2Ah rating is sufficient for smaller loads. Product B’s 9Ah rating supports slightly heavier demands. Choose based on your UPS model’s requirements.
UPS Model Compatibility
Product A fits APC BN1080G, BR1000G, BR1000GI, BX1000G, BX1300G, SMT750RM2U, SMT750RMI2U, and BN1350G systems. It replaces APC RBC123. Product B fits BX1500M, BR1300G, BX1500G, BR1500GI, BR1500G, BX1300G, and SMC1000-2UC units. It replaces APC RBC124. Both cover BX1300G, but their other compatible models differ significantly. Check your UPS model number carefully. Using the wrong battery can cause errors. Product A is for specific Back-UPS Pro systems. Product B covers broader BX and BR series models.
Physical Dimensions
Product A measures 7.85 inches wide, 6 inches high, and 3.09 inches long. Product B measures 7.88 inches wide, 3.09 inches high, and 6 inches long. The dimensions are swapped between height and length. Product A is taller but thinner. Product B is shorter but deeper. Both have similar widths around 7.85 inches. Ensure your UPS battery compartment can accommodate the specific orientation. The swap in height and length affects how the battery sits in the enclosure.
Weight
Product A weighs 2.87 pounds. Product B weighs 11.2 pounds. This is a significant difference in mass. Heavier batteries often indicate denser lead plates, which may correlate with the higher capacity. The lighter weight of Product A makes it easier to handle during installation. Product B’s substantial weight requires more care when lifting. Consider the weight limit of your UPS chassis. The difference is over eight pounds. Handle both units with appropriate care.
Included Accessories
Both products include a complete, ready-to-install kit. Each comes with brand-new connectors, cables, fuses, and a metal enclosure. This means you do not need to buy extra parts for installation. The pre-assembled nature speeds up the replacement process. Both units are maintenance-free sealed lead-acid designs. They feature suspended electrolyte for safety.
