The APC BX1500G is a 1500VA/865W line-interactive Uninterruptible Power Supply (UPS) designed to protect electronics from power outages and surges, offering 10 NEMA 5-15R outlets (5 battery backup, 5 surge), automatic voltage regulation (AVR) for stable output, and runtimes of about 4 mins at full load or 13 mins at half load. It's a common model for home/office use, often needing replacement batteries (typically two 12V SLA batteries) after a few years, with compatible replacement packs readily available.
