Pro Mariner 12132 Battery Isolator 2 Alternator 2 Battery 130 Amp

The Pro Mariner 12132 Battery Isolator is a professional-grade charging management solution designed for dual alternator, dual battery systems requiring up to 130 amps of current capacity. This high-performance isolator enables independent charging of two separate battery banks from two alternator sources, preventing power drain between batteries while maintaining optimal charge efficiency.

Key Features:

• 130 amp continuous duty rating for high-demand electrical systems
• Dual alternator, dual battery configuration for maximum flexibility
• Gold-plated terminals provide superior conductivity and corrosion resistance
• Improved efficiency design reduces voltage drop during charging
• Diode-based isolation prevents battery cross-discharge
• Heavy-duty construction for marine and commercial applications
• Suitable for boats, RVs, emergency vehicles, and work trucks

Pro Mariner battery isolators utilize advanced diode technology to automatically direct charging current to the battery that needs it most, while preventing electrical backflow that can drain batteries when the engine is off. The gold-plated terminals ensure reliable long-term connections even in harsh marine environments with salt spray and moisture exposure.
