Product Description
The PS-1227 is part of our General Purpose SLA range. This 12.0V and 2.9Ah battery provides dependable power for general purpose and standby uses. Features include AGM Technology, Gas Recombination, Power Volume Ratio, SLA ABS Case, and SLA Maintenance Free. These batteries are commonly used in Emergency Lighting, Fire Security, General Purpose, Medical, Signaling (Air,Rail,Sea), Solar, Telecomm, UPS, Utility, and Wind requiring reliable, light cyclic backup power. 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.
Charging Description
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.
