Vertiv Liebert APS 10A Battery Charger Module | For Reduced Battery Recharge Times

The Vertiv Liebert APS 10A Battery Charger Module is a purpose-built upgrade for Liebert APS UPS systems, engineered to dramatically shorten battery recharge times and maximize availability for mission-critical applications. By integrating seamlessly with the APS FlexPower assemblies, this 10-amp charger module adds robust charging capacity without sacrificing reliability or system footprint. If your operation requires minimal downtime between outages, faster battery recharging, and scalable power management, the APS 10A Charger Module is designed to meet those demands while preserving the core benefits of the Liebert APS platform: proven reliability, modular growth, and intelligent energy storage management.

• Faster recharge times with 10A charging current: This dedicated 10-amp charger module accelerates the replenishment of battery banks after discharge events. In data centers, telecom hubs, and other critical facilities, reduced recharge time translates to higher readiness for the next load step and improved service levels. By distributing charging work across multiple modules, you minimize the time the UPS spends replenishing energy, helping maintain output integrity during peak demand windows.
• Parallel operation with APS FlexPower chargers: The APS 10A Charger Module is designed to work in parallel with chargers in the APS FlexPower assemblies. This parallel configuration optimizes charging efficiency, balances current sharing, and reduces charging bottlenecks that can occur when relying on a single charger path. The result is a more responsive battery system that supports rapid transitions from standby to active power delivery when the utility or generator input fluctuates.
• Supports 3:1 battery module to power module ratios: A key capability of this module is its support for favorable battery-to-power configurations. By enabling 3:1 ratios, the Liebert APS UPS can scale charging capacity against larger battery strings, preserving ample headroom for growth and ensuring fast recharge without overtaxing any single component. This flexibility is ideal for facilities planning for future battery capacity or seasonal demand spikes.
• Modular, scalable design integrated with Liebert APS infrastructure: The Charger Module is designed to slot into existing Liebert APS architectures, maintaining a compact footprint and clean cable management. Its modular approach means you can add charging capacity incrementally as your energy storage strategy evolves, without a full UPS replacement. The integration preserves the UPS’s diagnostic visibility, ensuring you can monitor charge health, temperature, and current sharing through the standard Liebert APS management tools.
• Reliability and readiness for mission-critical environments: Built to withstand the rigors of data centers, telecom facilities, and other environments where uptime is non-negotiable, the 10A Charger Module adheres to rigorous testing and quality standards. Its robust engineering supports continuous operation, reduces recharge latency, and helps ensure that systems recover quickly from outages or long-duration discharge events. By delivering stable, predictable charging performance, it contributes to longer battery life, better state-of-charge management, and improved overall system reliability.

How to install Vertiv Liebert APS 10A Battery Charger Module

• Power down the Liebert APS UPS and follow your site’s standard safety procedures for handling energized equipment. Verify you have the appropriate maintenance window and necessary protective equipment before handling battery connections.
• Confirm compatibility with your APS FlexPower assemblies and ensure that space and connectors align with the APSCHRGRMOD installation requirements. Review any available Liebert APS documentation or on-site schematics to identify the correct mounting location and connector interface.
• If replacing an existing charger module, disconnect the old unit first following proper de-energization procedures, then prepare the mounting surface and cable routing for the 10A charger module. When adding capacity, position the new module in the designated slot within the FlexPower assembly to maintain orderly cabling and airflow.
• Secure the 10A Charger Module to the enclosure or rack per the manufacturer’s guidelines, ensuring a solid mechanical fit. Connect the electrical interfaces to the corresponding charging bus and power connections, following any color coding or labeling conventions used by your system.
• Power up the system and perform a post-installation check. Verify that the new charger module is recognized by the UPS management software, monitor the charging current distribution, and confirm that battery recharging accelerates as expected across the parallel charging pathway. If the system includes diagnostics or firmware checks, perform the appropriate updates to ensure full interoperability with the added module.
• Test battery discharge and recharge cycles under controlled conditions to validate that the 3:1 ratio capability is functioning as intended and that no abnormal thermal or electrical readings are present. Document the results for preventive maintenance records and future capacity planning.
