Symmetra RM 8-12kVA Battery Module

The APC SYBT3 is a maintenance-free sealed lead-acid battery module designed for Symmetra RM 8-12kVA UPS systems. It provides a volt-amp-hour capacity of 808 and uses suspended electrolyte technology for leakproof operation. This internal battery module fits a 0U rack form factor. It is intended for IT managers maintaining critical power infrastructure.

Replaces Worn Symmetra Battery Cartridges

This module replaces depleted internal batteries inside compatible Symmetra RM units when runtime drops below acceptable levels. The jump is worth it when the existing batteries reach the end of their expected three-to-five-year service life. Swapping the module restores full backup capability without replacing the entire UPS frame. It targets administrators scheduling proactive maintenance windows.

Verify Symmetra RM Compatibility First

Confirm the UPS chassis is a Symmetra RM model rated for 8-12kVA before ordering. The module measures 6.5 inches wide, 5.3 inches high and 23.1 inches deep, weighing 62.00 lbs. Ensure the rack bay accommodates these dimensions and weight. Installation requires handling a 28.18 kg unit, so plan for safe lifting procedures.
