APC SYBT5 - Battery Module 120 V Lead-Acid

Overview

The APC SYBT5 is a plug-in maintenance-free lead-acid battery module designed for use in APC Symmetra LX uninterruptible power systems. It provides stored DC energy to extend runtime during mains failures and supports UPS internal battery management.

Internally configured as a sealed battery cartridge with multiple cells, this unit delivers a nominal 120 V output. Its construction includes an enclosed battery assembly that simplifies installation and ensures safe integration into compatible UPS chassis.

Engineered for hot-swappable service, the SYBT5 permits battery replacement without powering down the host UPS, reducing service interruptions. Care should be taken to follow standard battery handling and UPS procedures to avoid electrical hazard or cell damage.

Physical dimensions and form factor are tailored to the Symmetra LX internal battery bay, ensuring a secure fit. The module includes internal battery management circuitry to support charging and communication with the UPS.

This module is not a standalone UPS; it must be installed within a compatible Symmetra LX system. It does not provide utility power output on its own and cannot be connected directly to external loads or power feeds.
