View TITAN SeriesUPS Battery Replacement for Existing Systems
A replacement battery must match the UPS DC system, charger, measured load, runtime target, cabinet, wiring, protection and site environment.
Compare UPS battery cabinets and replacement batteries using the UPS battery replacement checklist. For a chemistry change, review the lead-acid to lithium upgrade requirements first.
Customer situation
- The battery bank has aged, failed a test or no longer meets the runtime target.
- The UPS itself may still be serviceable, but its condition must be checked.
Load and runtime
- Use measured load and the required operating objective.
- State assumptions behind any runtime estimate.
UPS architecture
- Record UPS model, rated capacity, DC voltage and charger information.
- Identify active charger, inverter or control faults before battery supply.
Battery configuration
- Verify series quantity, parallel strings, chemistry, Ah and terminal layout.
- Inspect cabinet, cables, breaker or fuse and polarity marking.
- Compare lead-acid replacement, cabinet changes and lithium evaluation separately.
Site limitations
- Cabinet condition and usable space
- Ventilation, temperature and maintenance access
- Cable length, protection and floor loading
Maintenance considerations
- Keep batteries within a matched and controlled string.
- Record installation date and inspection basis.
- Do not mix incompatible ages, chemistries or specifications.
Procurement questions
- Is the UPS charger operating correctly?
- What is the verified string arrangement?
- What measured load and runtime are required?
- Can the existing cabinet and protection be reused?
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
- Quoting from old battery quantity alone
- Treating UPS capacity as the actual load
- Expecting new batteries to repair an existing UPS fault
