Lead-Acid to Lithium Upgrade

A UPS lithium upgrade is a compatibility project involving voltage window, charging, BMS, protection, communication, service and local requirements.

Customer situation

The customer wants to review footprint, maintenance or lifecycle objectives.
An existing lead-acid bank is due for replacement.

Load and runtime

Confirm measured load and required backup duty.
Do not assume equal nominal Ah produces equal project runtime.

UPS architecture

Identify the exact UPS model, DC operating window and charging logic.
Confirm required interlocks, dry contacts or communications.

Battery configuration

Review battery nominal and operating voltage, usable capacity and current.
Coordinate BMS, breaker, contactor, fusing, cable and cabinet.
Confirm charger voltage, current and restart behavior.

Site limitations

Installation environment and equipment clearances
Local commissioning and emergency isolation
Destination standards and transport documentation

Maintenance considerations

Define local BMS and alarm support capability.
Keep configuration, firmware and communication records.
Plan safe replacement and end-of-life responsibilities.

Procurement questions

What exact UPS and charger behavior must the battery support?
Is communication mandatory or are dry contacts acceptable?
Who will commission and service the system locally?

Delivery and documentation

Confirm the selected model, accessories and packing list in writing.
Confirm certification and shipping documents by model and destination.
Define who handles installation, commissioning and local service.

Project risks

Treating lithium as a physical drop-in replacement
Selecting from UPS power or nominal voltage only
Leaving communication and protection behavior undefined
