APC Battery Module for Symmetra PX, Smart-UPS VT or Galaxy 3500

The APC SYBT4 is a battery module that serves as either a replacement or an additional capacity unit for Symmetra PX, Smart-UPS VT, and Galaxy 3500 uninterruptible power supplies. It provides 384 volts of direct current and stores 2765 VAh, giving servers, networking hardware, or industrial controllers the breathing room they need during an outage or while a generator starts.

The sealed cartridge contains four individual lead-acid batteries and mounts directly inside the UPS chassis. Because the module is hot swappable, you can remove or install it while the UPS remains online, so critical systems keep running and user sessions stay active.

Data center managers, network administrators, and facility engineers often choose this module when predictable runtime is essential during scheduled maintenance or when extending protection for newly added equipment. Adding or replacing a SYBT4 takes only a few minutes and requires no special tools, which helps keep maintenance windows short.

The maintenance-free lead-acid chemistry performs best in ambient temperatures from 32 to 104 degrees Fahrenheit. Under recommended conditions the module can provide a service life of up to six years, reducing the frequency of battery changes and lowering total cost of ownership.
