UPS Battery Cabinet — VRLA and Lithium Battery Enclosures
Battery cabinets for UPS systems, with ventilation, fault protection and matching cabinet dimensions.
Battery cabinets house UPS batteries with ventilation, temperature control and racking. They support 10 to 30 minutes of runtime at full load, with VRLA or lithium batteries and sizes matched to the UPS frame.

Battery cabinets are sized by battery type, capacity, runtime and UPS DC voltage. The cabinet must match the UPS and the room layout.
Lithium cabinets include a BMS and may require different fire protection from VRLA. The project should state the battery chemistry.
Best for
- UPS rooms and micro data centers
- Projects needing extended runtime
- Replacements with a defined battery chemistry
