Solar Lead-Acid Batteries 12V 75Ah Gel Battery for Solar Panels
Product Description
Batteries are designed to be deeply discharged and recharged hundreds of times. They are designed and built differently than traditional flooded batteries. Batteries are sealed lead-acid batteries made with Absorbed Glass Mat (AGM) technology. The electrolyte is absorbed into the fiber separator material rather than in free-flowing liquid form. They use more lead, heavier plates, and other proprietary materials that enable them to deliver more power and capacity over many life cycles.
