Direct UPS Replacement

The Thinkstar RBC43-UPC is a maintenance-free sealed lead-acid battery designed as a drop-in replacement for compatible APC UPS units. It arrives pre-charged and includes all required connectors, cables, fuses and enclosures so installation requires no assembly. The plug-and-play, hot-swappable design allows you to swap the battery without powering down connected equipment. An installation and recycling guide is included in the package.

Compatibility List Decides Fit

This battery replaces the RBC43 assembly and fits the APC models DLA2200, DLA3000, SMT2200, SMT3000, SUA2200, SUA3000, SUM1500, SUM3000 and the SUM48RMXLBP2U extended battery pack. If your UPS model is not on this list the part will not work. No other specifications determine suitability; the model match is the only deciding factor.

Handles Listed UPS Runtime

The sealed lead-acid cells deliver the rated capacity for the UPS models named above, supporting their standard backup time during mains failure. Runtime scales with the connected load, so heavier loads exhaust the reserve faster. The battery is not intended for units outside the compatibility list or for applications requiring longer autonomy than the host UPS is rated to provide.
