When choosing a UPS, you can consider things like:

• The type of UPS you need
• How much power your equipment needs
• The voltage your equipment needs
• How much battery backup runtime you need

When handling UPS batteries, you should:

• Wear safety equipment like gloves and safety goggles
• Handle the batteries with care to avoid spills or leaks
• Use sturdy, non-conductive containers to transport the batteries

An uninterruptible power supply (UPS) works by switching to battery power when there is a power outage or abnormal voltage:

• Input: A UPS normally takes in AC power and outputs it to connected devices.
• Detection: When there is a power outage or abnormal voltage, the UPS detects it.
• Switching: The UPS switches to battery power, which is then inverted to AC power to run the connected equipment.
• Protection: A UPS protects connected devices from power problems like voltage sags, surges, brownouts, and line noise.
• Backup: A UPS provides backup power for a short time, which can be enough to start a standby power source or shut down the connected devices.
• Battery life: The length of time a UPS can run on battery power varies by system, but is usually only a few minutes.
