UPS back-up batteries are a critical necessity as a power surge or power outage could cost a lot of wasted time and money, lost data and damaged equipment. Although UPS back-up batteries are an obvious necessity, it is surprising to find out that a lot of businesses rely on nothing more than a simple surge protector or PDU to power their servers and workstations.

The APC Smart-UPS SRT 5000VA (SRT15KXLI) offers longer run-times and power output to ensure even the most sensitive electronics are properly protected. Further, this business class UPS back-up battery also offers remote management functionality, allowing it to be monitored from a central location.

Looking at the specifications, the APC Smart-UPS SRT 5000VA (SRT5KXLI) sits in the middle of the Smart-UPS lineup, designed to protect maximum loads of up to 4500W or 5000VA.


APC Smart-UPS SRT 5000VA ensures clean, uninterrupted power to protect equipment’s while batteries are being replaced. After the UPS shutdowns, it automatically restarts its loads. It also automatically starts up the connected equipment upon the return of utility power.

It maximizes battery performance, life, and reliability through intelligent, precision charging. The UPS supplies utility power to the connected loads in the event of a UPS power overload or fault. It prolongs battery life by regulating the charge voltage according to battery temperature.


The UPS avoids costly power problems by keeping the IT equipment and data protected and available. Network grade power conditioning protects from damaging surges and disruptive noise. The double conversion architecture provides tight voltage regulation, frequency regulation, and zero transfer time to battery during power events. One unique quality of this UPS is that it has low operating and maintenance costs with proven reliability and intelligent battery management.

Intelligent battery management, pioneered by APC, maximizes battery performance and life through an intelligent, precision temperature compensated charging. Automatic self-tests insure battery reliability and warn customers in advance of battery replacement. Convenient, easy to connect, hot-swappable battery modules provide battery replacement without powering down.

The UPS provides peace of mind that comes with full equipment compatibility and reliability of a leader. It enables the user to save time with easy and convenient remote/network accessibility.

The UPS recovers easily from overloads and there is no need to replace a fuse. It protects connected loads from surges, spikes, lightning, and other power disturbances. It minimizes installation costs by enabling the use of smaller generators and cabling. It also ensures clean, uninterrupted power to protected equipment when generator power is used and it provides temporary battery power when the utility power is out.


The UPS carries out periodic battery self-test runs to ensure early detection of a battery that needs to be replaced. It also gives a warning when a battery is not available to provide backup power. It provides an early-warning fault analysis that ensures proactive component replacement.

It increases availability by allowing a trained user to perform upgrades and replacements of the batteries reducing Mean Time to Repair (MTTR). Lastly but not the least, it has audible alarms that provide notification of changing utility power and UPS power conditions.
