Mighty Max ML9-12GEL 12V 9AH GEL F2 Replacement Battery — Compatible with Liebert/Emerson PSP600 UPS (2-Pack)

ML9-12GEL by Mighty Max is a 12V 9AH GEL rechargeable, maintenance-free battery sold as a 2-pack. Engineered as an F2 replacement for Liebert / Emerson PSP600 UPS units, this battery offers dependable backup power in a compact form. Long-term charge retention: The GEL construction yields a slower self-discharge rate compared to AGM batteries, so these cells hold their charge longer when idle — an advantage for standby and backup applications. Reliable across temperatures: Designed to perform consistently in a wide range of climates, these batteries withstand temperature swings and maintain steady power delivery in both hot and cold conditions. Robust, safe design: A thick, non-spillable gel paste minimizes leakage and reduces the risk of acid spills and harmful fumes. The gel electrolyte also helps the batteries resist vibration and shock, making them suitable for demanding or mobile environments. Proven brand and performance: Mighty Max is recognized for quality and durability. The ML9-12GEL combines advanced GEL technology with enhanced safety features for improved discharge behavior, reliable operation, and extended service life.
