WTF is battery backup? just call it UPS. If they would call it UPS I'd know what they're talking about!

battery backup (UPS) to keep critical equipment running smoothly during those brief power interruptions.

Battery backup = UPS

Across most categories, battery backup systems come out on top. In short, they're better for the environment, easier to install and cheaper to run long-term. Plus, they have longer warranties than standby generators.

B. Battery backup To mitigate micro power outages, such as short power interruptions lasting a few minutes, a battery backup, often referred to as an uninterruptible power supply (UPS), is the most appropriate solution. A UPS provides a temporary power source during such interruptions, allowing connected devices to continue operating without disruption. This can be crucial for preventing data loss or damage to sensitive equipment. A surge suppressor (A) is designed to protect against voltage spikes and surges but doesn't provide backup power. A CMOS battery (C) is a small battery on a computer's motherboard that primarily maintains the system's hardware clock and BIOS settings; it does not address power outages. A generator backup (D) is a more substantial and longer-term solution typically used for extended power outages, not micro outages lasting a few minutes.

Guessing it is going to take long for a generator to come on. Battery makes sense .
