Power-Sonic PS Series | 12V Sealed Lead Acid Battery

FAQs

What is the difference between the PS-1290 F1, F2, and NB1 terminal options?

The PS-1290 is available with three terminal configurations to suit different installation requirements. The F1 variant features 0.187-inch (4.75mm) Faston quick-disconnect tabs, while the F2 version uses larger 0.250-inch (6.35mm) Faston terminals for higher current applications. The NB1 option provides M5 threaded terminal posts with nut and bolt connectors, offering the most secure connection method with torque specifications of 2.0-3.0 Nm, ideal for applications requiring vibration resistance or multiple wire connections.

How long will the PS-1290 battery last in standby applications?

When used in standby or float service applications with proper charging at 13.5-13.8V and maintained at 25°C ambient temperature, the PS-1290 offers an expected service life of approximately 5 years. However, battery life is significantly affected by operating temperature – higher temperatures accelerate aging while lower temperatures can extend service life. At 40°C, the float life may reduce to around 2 years, while operation at 20°C can extend life beyond 5 years. Regular maintenance checks and proper charging practices are essential to maximize battery longevity.

Can the PS-1290 be used in both float and cyclic applications?

Yes, the PS-1290 is specifically engineered as a dual-purpose battery suitable for both standby float service and light cyclic applications. For float service in UPS, emergency lighting, or alarm systems, the battery should be charged at 13.5-13.8V constant voltage. For cyclic applications requiring regular discharge and recharge cycles, use a higher charging voltage of 14.1-14.7V. While the battery can handle cyclic use, it’s optimized for light cycling rather than deep discharge applications – the cycle life data shows the battery can deliver 100-300 cycles depending on depth of discharge, with deeper discharges significantly reducing cycle count.

What charging voltage should I use for the PS-1290?

The correct charging voltage depends on your application type. For standby or float service, apply a constant voltage of 13.5-13.8V (2.25-2.30V per cell) at 20°C ambient temperature. For cyclic applications involving regular discharge and recharge cycles, use 14.1-14.7V (2.35-2.45V per cell) with initial charging current limited to less than 1.8A (C/5 rate). Temperature compensation is critical – reduce charging voltage as temperature rises to prevent overcharge, and increase it as temperature falls to avoid undercharge. Consult the Power-Sonic Technical Manual for specific temperature compensation factors to ensure optimal charging across varying ambient conditions.

Is the PS-1290 suitable for security and fire alarm systems?

Absolutely – the PS-1290 is specifically designed for use in fire and security system applications. Its sealed, maintenance-free construction makes it ideal for alarm panel installations, while the multiple terminal options accommodate various panel connection requirements. The battery’s wide operating temperature range and reliable float service characteristics ensure consistent backup power for detection devices, control panels, sounders, and communication equipment. With VdS certification for alarm systems and compliance with relevant safety standards, the PS-1290 meets the stringent requirements of professional security and fire detection installations, providing dependable emergency power when mains supply is interrupted.
