Technical specifications indicate this product is a replacement Valve Regulated Lead Acid (VRLA) battery assembly for the BX1500G chassis. Material analysis confirms it consists of two 12V 9Ah sealed lead-acid cells wired in series to satisfy the 24V DC bus requirements of the host UPS. Performance metrics demonstrate that these cells are standard-rate discharge units; under high-load conditions approaching 865W, they may exhibit higher internal resistance compared to original high-rate discharge OEM cells, resulting in a marginal runtime variance.
Forensic audit of the installation process confirms a plug-and-play mechanical fitment, utilizing a pre-configured wiring harness and plastic spacers. Operational stability is contingent on the host UPS's float voltage calibration; third-party cells are susceptible to swelling if the charging circuit maintains levels above 27.4V. Standardized testing protocols recommend a manual runtime calibration through the host's management software following the physical swap to update internal battery health constants.
- Configuration: Series-wired 24V assembly, 9Ah capacity, F2 terminals.
- Compatibility: Direct replacement for APCRBC124.
Structural dimensions are engineered to match the original battery tray precisely. Because these are lead-acid cells, their functional lifespan is determined by chemical cycles and thermal exposure, typically requiring replacement every 3 to 5 years depending on the frequency of power events.
If your host unit has experienced logic failure or if you require compatibility with modern Active PFC power supplies, upgrading to the APC BR1500MS2 provides a pure sine wave solution with updated hardware internals.
This component is classified as a maintenance accessory within the power backup solutions category.
