Marine Batteries

The #1 killer of batteries is acid stratification.
That's bad. We fixed that.

Image

Traditional Batteries

Acid stratification happens when the heavier acid separates from the water in the battery's electrolyte and settles at the bottom of the battery, causing excess corrosion and charge imbalance.

MIXTECH Batteries

Incorporate patented MIXTECH technology that uses the motion of your vehicle to continuously mix the electrolyte preventing acid stratification.
