PHR-1290

Optimized for short-duration, high-current discharge, these batteries deliver excellent power density, reliable valve regulation, and dependable performance.

The PHR-1290 FR is part of our High-Rate Discharge range. This 12.0V and 20.7Ah battery provides high-density rapid power. Features include Dual Paste, High-Rate UPS Application, Plate Pasting, SLA ABS Case, and SLA Maintenance Free. These batteries are commonly used in Backup Power Systems, Edge Data Center, Telecomm, and UPS requiring short-duration high-current discharge. 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.
