Purpose-Built UPS Replacement

The Battery Technology Inc. SLA25-BTI is a direct replacement battery module designed for the SU1400RMXL3U uninterruptible power supply. It restores backup runtime when the original cells reach end of life. The unit is supplied new and ready for immediate installation.

Compatibility & Limitations

This battery suits owners of the SU1400RMXL3U who need to regain full runtime without replacing the entire UPS. It will not fit other UPS models or chassis configurations. Buyers who need a different voltage, form factor, or connector should look at other SKUs.

Installation Notes

The module slides into the UPS battery compartment and connects with the existing harness; no tools are typically required. Common issues include forgetting to disconnect the UPS from mains before starting and failing to seat the connector fully, which prevents the self-test from passing.
