MK Deka 908DFT 12VDC Flooded Lead-Acid Battery

Deka 908DFT Heavy-Duty 12V Commercial Battery (Group 8D)

Engineered by East Penn, the Deka 908DFT is a high-capacity, 12-volt commercial starter battery purpose-built for high-displacement diesel engines, line-haul tractors, dump trucks, buses, and heavy agricultural equipment. It utilizes a calcium-lead alloy hybrid construction that reduces fluid gassing, delivering long-term, maintenance-free waterless operation under grueling work cycles.  

Designed with a Top Right-Hand Positive layout (BCI Code 4), this unit drops straight into standard commercial engine bays, ensuring direct alignment with standard-reach fleet battery cables without requiring cable splicing or tight wire stretching. 

Key Features: 

• Anti-Vibration Design: Internal parts are locked down tightly to survive heavy shaking on rough work sites.
• Short-Circuit Protection: Sealed internal pockets keep parts from touching and causing dead cells.
• Winter Starting Power: Sends a strong 1425 CCA pulse to turn over heavy diesel engines in freezing weather.
• 7-Hour Power Backup: Keeps your vehicle's lights and dashboard electronics running if your alternator fails.
• No Cable Stretching: The right-hand positive post matches standard commercial cables perfectly for a quick drop-in fit.
• Easy Lift Case: Built with tough plastic that resists cracks, featuring thick rope handles to lift the 127-pound block safely.
