The CSB HR 1227W F2FR is a 12V 27W high-rate, sealed lead-acid (SLA) battery utilizing Absorbent Glass Mat (AGM) technology. It's often associated with a 5Ah (Ampere-hour) capacity, though some sources specify 6.5Ah, and its key characteristic is its ability to deliver high power for short durations.
This battery is specifically designed for high-efficient discharge applications, making it ideal for UPS (Uninterruptible Power Supply) systems, emergency lighting, security systems, fire alarms, and other critical backup power needs. The "F2FR" designation indicates it has F2 terminals (0.250" wide) and a Flame Retardant (FR) case, enhancing safety. It's maintenance-free, leak-proof, and offers a design life of 3-5 years in standby service.
