12V38AH Gel Deep Cycle Battery with 12 Years Design Life and Maintenance Free for Solar Power

12V38AH Deep Cycle Battery for Solar Power Gel Deep Cycle Battery Maintenance Free Gel Battery

This series is designed for frequent cyclic charge and discharge applications under extreme environments. By combining the newly developed Nano Gel electrolyte with high density paste, the Solar range offers high recharge efficiency at very low charge current. The acid stratification is highly reduced by adding Nano Gel.
