Key Design Features
-
Deep Cycle Endurance: Formulated with thick, heavy-duty plates designed to sustain repetitive deep discharge and recharge cycles without premature capacity loss.
-
AGM Spill-Proof Design: Completely sealed valve-regulated construction locks the electrolyte within fiberglass mats, allowing safe installation in internal compartments, RVs, and marine setups.
-
Low Self-Discharge: Low internal resistance and minimal fluid evaporation ensure extended shelf life and reliable energy retention during prolonged periods of storage.
