How to Use APC Battery Backup: Setting Up and Reviewing the APC 550 UPS

Welcome to another how-to tutorial from US Computer Solutions! In this tutorial, we will be setting up and reviewing the APC 550 UPS. If you’re interested, we’ve included a link to purchase it in the description below.

To start, flip the device over and release the two connectors on the bottom. Once these are released, plug them in to activate the batteries inside. Before plugging the device into the wall, test the batteries by pressing the button on the front. If it gives you a green light, the batteries are active.

The device is now running on batteries, indicated by the “battery surge” label. This is where you can plug in small equipment like monitors, desktops, scanners, and printers. However, do not plug in heavy equipment like vacuums or large copiers, as the APC backup will not support it and could run the fuse.

For slightly heavier equipment, there is a plug labeled “battery backup + surge protection.” This will protect your equipment from small surges, but if there is a power outage, your devices will still turn off. For true backup protection, use the plug labeled “battery backup.”

Now that we’ve connected our equipment to the APC, it’s time to plug it into the wall. Once it’s plugged in, turn it on. If the light is steady, the device is connected to the wall and will provide power to any connected devices. In the event of a power outage, the device light will start blinking. Once the battery runs out, the device will turn off.

We hope this tutorial has been helpful in setting up and reviewing the APC 550 UPS. Remember, it’s important to protect your equipment from power surges and outages, and a battery backup like this one can help ensure your devices stay on during an outage.

Do I need to charge APC UPS before using?
The battery is fully charged at the factory. However, it is recommended to charge the battery at least 8 (eight) hours before using the UPS, since energy loss may have occurred during shipping or long duration storage. To recharge the battery, simply leave the UPS plugged into an AC outlet.
