STATIONARY SEALED LEAD-ACID BATTERIES (VALVE REGULATED TYPE) Application Used as normal-service and emergency DC power supply for substation in combination with charging rectifier. Basic specifications 1. Terminal voltage of one battery cell (during floating charge): 2.23±0.1[V] 2. Nominal voltage of one battery cell: 2[V] 3. Number of batteries per one set: 50 4. Capacity [10-hour rate]: selected from values below 150; 200; 300; 500; 1000; 1500; 2000; 3000[Ah] 5. Service conditions a. Method of charging: floating charge b. Ambient temperature: min.-10°C; max.40°C 6. Aseismatic structure Both batteries and stand should be able to endure the constant horizontal acceleration listed below, and not be damaged by the resonance load of earthquake. [Installation site] 7. - First floor or below 4.9[m/s2] (0.5G) 8. - Second or third floor 9.8[m/s2] (1.0G) - Fourth floor or above examined individually 9.
