Replacement UPS battery for APC RBC43

The Battery Technology Inc. RBC43-SLA43-BTI is a direct replacement battery designed for APC uninterruptible power supply units that use the RBC43 cartridge. It restores backup runtime for connected telephony equipment and network devices during mains failures. New condition ensures full rated capacity from first installation. Compatible with office VoIP and telephone systems requiring continuous power.

Sealed lead-acid cartridge rated for APC RBC43

The sealed lead-acid pack matches the original RBC43 form factor and voltage, delivering the same ampere-hour rating for standard load profiles. It comfortably handles typical desk-phone and router loads for the duration specified by the UPS manufacturer. Runtime decreases under heavier server or multi-device loads, so maximum backup time is only achieved with light power draw. No user-serviceable cells inside.
