APC SU48RMXLBP3U UPS battery Sealed Lead Acid (VRLA) 48 V

SU48RMXLBP3U/Smart-UPS 48V Battery Pack RackMount, 3U height Battery pack, Hot Pluggable, BLACK.
New battery pack, SU48R3XLBP, replaces the old battery pack, SU48RMXLBP3U, which is now phased out.
The new SU48R3XLBP, which is an improved version of the SU48RMXLBP3U, is compatible with the SU2200RMXLI3U, SU3000RMXLI3U and the new SU5000RMXLI5U.
The initial version of the SU48RMXLBP3U battery pack cannot be used with the 5kVA unit since the wire gauge is insufficient and the length of the plug cable is too short. Consequently, the SU48RMXLBP3U is being phased-out of production and replaced by the newer SU48R3XLBP.
