12V 100Ah Sealed Lead-Acid Battery

100AGM

MillerTech (AGM) Batteries are designed to be deeply discharged and recharged hundreds of times. They are designed and built differently than traditional flooded batteries. MillerTech AGM 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.

Solved my power issues
Replaced a 5 month old under performing battery with a new Millertech and problems were solved. The Millertech handles all my accessories and all my electronics.
