Complication was added by the venuescrowded performance schedule, whichmeant that all work had to be carried outovernight. The project was a complete turnkeyinstallation including: Removal and recycling of the oldbatteries and battery chargers Manufacture and supply of two newbanks of 190 SBM Ni-Cd cells, twochargers and a two-stage dioderegulator to maintain supply within tight voltage limits. An installation plan which avoidedinterfering with the busy performanceschedule Long-term product support andmaintenance.Two banks of SBM nickel-cadmium (Ni-Cd)batteries supportemergency power systemsLightweight long-lifebatteries and flexibleproject team Safts SBM Ni-Cd batteries have beenproviding the energy storage for backuppower systems at Australias iconic SydneyOpera House since 1992. Saft passed theaudition for this key supporting role at theprestigious 6,000 capacity venue thanks tothe high quality of its batteries, anexperienced project team and a detailedinstallation plan. Tucked away behind thescenes, the opera house battery room islocated down three narrow flights of stairsin a room where the maximum floorloading of the floor limits the weight of thebatteries that can be installed.
