Key Features
-
Premium AGM Technology: Incorporates highly efficient Absorbent Glass Mat (AGM) separators, achieving internal gas recombination of up to 99%. The core remains completely maintenance-free with zero water replenishment needed.
-
Non-Spillable VRLA Construction: Designed with advanced Valve Regulated Lead Acid (VRLA) safety architecture and a thick, high-impact ABS casing, ensuring leak-proof operation and flexible mounting options at any angle.
-
Heavy-Duty Lead-Calcium Grids: Manufactured with premium lead-calcium-tin alloy grids, providing lower internal resistance, superior recovery properties, and an exceptionally low self-discharge rate during seasonal storage.
-
Standard Spade Faston Terminals: Fitted with reliable, highly conductive quick-connect spade terminals (Faston tabs) to maintain stable electrical contact and prevent connection power drops.
