Direct replacement for APC BP650S

Under continuous load the cells maintain a stable voltage curve until the UPS initiates its low-battery shutdown sequence. The 44 Ah rating supports the 650 VA unit through extended outages rather than brief spikes. Replacement intervals remain aligned with the manufacturer service schedule.
