A Leoch 12V 150Ah UPS battery is a sealed lead-acid battery (SLA) designed for use in Uninterruptible Power Supplies (UPS) and other backup power applications. It provides 12 volts and 150 ampere-hours of capacity, making it suitable for providing reliable power during outages. These batteries are typically maintenance-free and utilize AGM (Absorbent Glass Mat) technology, which allows for efficient gas recombination and prevents the need for electrolyte maintenance.
