Steady voltage during extended outages

The lead-acid chemistry delivers stable output throughout a prolonged discharge rather than only in brief bursts. Internal resistance remains consistent as the cells deplete, so connected equipment sees clean power until the battery reaches its rated cutoff. This behaviour suits servers and network gear that must ride through long utility interruptions without voltage sag.
