What Are Battery Isolators?

Battery isolators are electronic devices that allow a single alternator or charger to charge multiple batteries without connecting them directly. This prevents one battery from draining another and ensures that critical systems—like engine starting—always have dedicated power.

Key Features & Benefits:

• 
  Dual & Multi-Bank Charging
  Charge two or more batteries simultaneously from one alternator or charger while keeping them electrically isolated.
  
• 
  Protects Starting Battery
  Prevents house loads from draining the engine battery, ensuring reliable starts every time.
  
• 
  Automatic Voltage Sensing
  Advanced models detect battery voltage and direct charging current where it’s needed most.
  
• 
  Heavy-Duty Construction
  Marine-grade isolators are built to withstand vibration, moisture, and saltwater exposure.
  
• 
  Easy Installation
  Compact designs with clear labeling and mounting hardware make setup straightforward for DIYers and professionals alike.
