Battery module for Symmetra RM 2-6kVA UPS

This APC SYBT2 battery module is a direct replacement for Symmetra RM UPS units rated from 2 to 6 kVA. It contains a single maintenance-free sealed lead-acid battery with suspended electrolyte that is leakproof. The unit installs internally and is designed to restore original runtime when the existing batteries reach end of life.

Suitable for scheduled UPS maintenance.

This module fits administrators who perform planned battery refreshes on compatible Symmetra RM systems. It does not suit installations that use other UPS brands, different Symmetra form factors, or configurations requiring multiple battery cartridges at once. Buyers needing extended runtime beyond the standard capacity should look at additional modules or higher-capacity UPS models.

612 VA·h capacity per cartridge

Each SYBT2 cartridge delivers a rated capacity of 612 volt-ampere-hours, which determines the available backup time for the connected load. Matching this figure to the UPS rating and load profile confirms whether a single module meets the required autonomy or if extra cartridges are necessary.

Questions about this item

What comes in the box with the SYBT2 battery module and is any extra hardware needed?

The module is a single sealed lead-acid battery unit weighing 49.00 lbs; mounting hardware for the Symmetra RM chassis is not included and must be sourced separately.

How do I know the SYBT2 is the correct capacity for my 2-6 kVA Symmetra RM UPS?

The unit provides a 612 volt-amp-hour rating and is designated as the direct replacement for Symmetra RM 2-6 kVA frames, matching the original RBC quantity of 1.

What does the 612 VAH rating mean for actual runtime once the module is installed?

Runtime depends on the connected load and the number of modules in the frame; the 612 VAH figure represents the energy capacity of this single battery cartridge under standard conditions.
