The DELTEC DEL-UMFN55 is designed to meet the demands of vehicles requiring higher cranking power and reliable performance. It is part of the Ultra Maintenance Free (UMF) Series, which delivers improved Cold Cranking Amps (CCA) and Amp Hour capacity. This model is commonly used as a direct replacement for the S550 Ford Mustang battery due to its upgraded specifications. The UMFN55 is built to handle the electrical needs of performance and modified vehicles while maintaining stable output. It uses enhanced materials to support durability under high-load and high-temperature conditions.
This battery is built with Advanced Calcium lead-acid plates, suited for modern vehicles using higher voltage charging systems. The sealed, maintenance-free design means there is no need to check fluid levels, and performance can be monitored through routine service intervals. For vehicles exposed to constant vibration, the UMFN55 includes SMF X-Frame Plus technology and a reinforced internal grid structure for extra strength. These features support better conductivity and allow faster charging compared to standard batteries.
