Compatible UPS Replacement

The GreenTechLLC RB1290 is a 12V 9AH sealed lead-acid battery built to fit CyberPower UPS units including the AVRG900LCD, AVRG900U, BRG1000AVRLCD, CP1000AVRLCD, CP1000PFCLCD, CP800AVR, CP825AVRLCD, CP825LCD, CP850AVRLCD, CP850PFCLCD, LE1000DG and LE1000DG-FC models. It replaces the OEM RB1290 part directly. Buyers needing a different voltage, capacity or terminal type will not be served by this unit.

F2 Terminal Installation

Each battery arrives tested, charged and ready to install with F2/T2 terminals that match the original connectors. The case measures 5.90" X 3.74" X 2.56" so it seats in the existing battery compartment without modification. Installers who reverse the polarity or force undersized wires onto the F2 tabs risk damaging the terminal posts and voiding the unit's readiness.

SLA Chemistry Limits

The 12V 9AH rating defines the energy the cell can deliver under standard UPS load profiles. Sealed lead-acid chemistry self-discharges over time and loses capacity if stored in a discharged state or exposed to high ambient temperatures. Systems that demand longer runtime than 9AH provides or that require lithium-based cycle life will need a different battery platform.
