These high-capacity 2V SLA batteries are built for demanding backup and energy storage systems, providing stable performance, exceptional longevity, and reliable operation even under elevated temperatures.
The PSS-2V900 is part of our 2V High Capacity range. This 2.0V and 800.0Ah battery provides resilience to high temperatures in demanding scenarios. Features include OPZV/PSS Overcharge Endurance, SLA ABS Case, SLA Discharge Recovery, Superior Cyclic, and Thick Plate 10-12yr Design Life. These batteries are commonly used in Signaling (Air,Rail,Sea), Solar, Telecomm, UPS, Utility, and Wind requiring stable performance in large scale installations. Backed by decades of expertise, Power-Sonic batteries are subject to stringent quality controls through each step of the manufacturing process to ensure compliance, performance consistency, and reliability.
Cycle Applications: Apply constant voltage charge at 2.35VPC – 2.45VPC (14.1 to 14.7 volts for 12V Monobloc) at 20°C. The initial charging current should be set at less than C/5 Amps. Switch to float charge when the current falls to a 3% capacity rate to avoid overcharging. Stand-By or "Float" Service: Apply constant voltage charge of 2.25VPC – 2.30VPC (13.5 to 13.8 volts for 12V Monobloc) at 20°C. When held at this voltage, the battery will seek its own current level and maintain itself in a fully charged condition. Temperature Compensation: Charging voltage for both cyclic and stand-by applications should be regulated in relation to ambient temperature. As temperature rises, charging voltage should be reduced to prevent overcharge and increased as the temperature falls to avoid undercharge. For further charging information, including temperature compensation factors, see the Power-Sonic Technical Manual.
