Whether you have a busy data center or web servers that need to be constantly online, UPS accessories help you ensure that your surge protection system is efficient at all times. Make sure to consider the coverage time provided by the UPS power bank, and to have replacement batteries for your UPS system if required.

The UPS Protects Data and Keeps the System Running

UPS stands for “Uninterruptible Power Supply”. This device is essential in mission-critical environments and data centers since it prevents downtime in case of electrical failure. It’s able to provide backup power, allow the computer or server to shut down properly and prevent data loss. Different types of UPS surge protectors are capable of providing backup power for different amounts of time. You can also set them up to alert the server when the battery is running low, so it will shut down correctly before the power source fails. 

Know When It’s Time to Get UPS Replacement Batteries

The battery in your UPS surge protector wears out over time, just like the ones inside your laptop and smartphone. It gradually loses its original capacity. Some UPS models test their batteries regularly to make sure they can offer enough backup power for the right amount of time. Use software to monitor how fast the battery loses capacity, or take note of the time it takes to go off. Luckily, UPS replacement batteries are easy to find and install. As a rule of thumb, you should replace the battery every three or four years.  Most UPS power supplies have a battery slot that's similar to the one on your laptop where you can find the worn-out battery.

UPS Network Management Cards Let You Monitor Your UPS Power Supply Via a Secure Network 

UPS network management cards, like the APC® AP9631 and APC AP9630, add extra functionalities to your UPS surge protector. They allow you to monitor your UPS system via a secure network browser using the IPv6 protocol. They use device encryption to connect via HTTPS/SSL, SSH and SNMPv3. These UPS accessories also notify you when a problem occurs, so you’ll be able to prevent downtime or data losses. Network management cards offer data and event logs to help you identify problems in advance.

External Battery Packs Extend the Uptime of Your UPS Surge Protector

Some UPS models can work with external batteries to offer even more protection from electrical failure. They work similarly to the power banks you use for your smartphone, as they extend the runtime of the UPS power supply after the battery inside has died. Most external battery packs come with a cord, which goes into a dedicated connector. Some models, like the Tripp Lite® BP72V18-2US, have daisy-chain connectors to add multiple battery packs to the same UPS surge protector. Many external UPS batteries have unique designs that allow you to stack them in racks and create a tidy set up in a data center. Browse Newegg to find all of the available power supplies today.
