Lithium batteries for UPS and critical backup power.
12.8V, 24/25.6V and 48/51.2V reference batteries reviewed against the UPS DC bus, load, runtime, recharge and cabinet constraints.
Runtime starts with the load—not the amp-hour label.
UPS sizing requires the real output load, power factor, inverter efficiency, backup duration, cutoff behavior and battery discharge rate. A battery with the same nominal voltage and Ah can deliver a different usable runtime under high-rate discharge.
This category supplies batteries for backup applications. It does not imply supply of the complete UPS host, automatic compatibility with a named UPS brand, or permission to replace an installed lead-acid battery without the equipment owner’s review.
Start from a real configuration, then confirm the project version.
Reference models demonstrate available form factors and engineering experience. Current drawings, component revisions, documentation, MOQ and delivery terms are reconfirmed before quotation.

Load & runtime
Convert actual load and backup time into a usable-energy and discharge-rate requirement.
DC bus & charging
Check operating window, cutoff, charge/float behavior, recharge current and low-temperature rules.
Mechanical integration
Verify rack/cabinet fit, cable/busbar path, ventilation, access, mass and parallel configuration.
Control & validation
Define BMS signals, alarms, fault isolation, test conditions and host-system acceptance.
What we confirm before supply.
| UPS input | Brand/model, DC bus range, load, power factor, efficiency and required backup time. |
|---|---|
| Battery output | Voltage architecture, Ah/kWh, current/rate capability, cutoff and usable operating window. |
| Charging | Charge profile, maximum current, float behavior, recharge target and temperature interlocks. |
| Integration | Rack/cabinet, cables, protection, parallel strings, BMS communication and system monitoring. |
| Boundary | Battery model and documents are confirmed separately from UPS host certification and facility design. |
Questions purchasing teams ask.
Can I put a lithium battery in an existing UPS?
Only after the UPS manufacturer or responsible integrator confirms electrical, charging, mechanical, communication and certification compatibility. Voltage alone is not enough.
How do I calculate UPS lithium battery runtime?
Use the actual load, conversion losses, discharge rate, operating voltage window, temperature and reserve. A simple Ah comparison can misstate runtime.
Do you sell a complete UPS?
This category is for lithium battery products used with UPS and backup systems. Complete UPS supply is not assumed.
Need a lithium battery for a UPS project?
Send the UPS model, DC bus, load, runtime, cabinet, recharge target and quantity.
