Key Features
-
Premium AGM Technology: Incorporates highly efficient Absorbent Glass Mat (AGM) separators, achieving internal gas recombination of up to 99%. The system remains completely maintenance-free with zero need for routine water replenishment.
-
Non-Spillable VRLA Construction: Built using a leak-proof Valve Regulated Lead Acid (VRLA) safety layout enclosed in a high-impact ABS casing. This allows for safe, spill-proof operation and flexible mounting setups at any physical angle.
-
High-Purity Lead-Calcium Grids: Manufactured with premium lead-calcium-tin alloy grids that provide lower internal resistance, superior recovery characteristics from deep discharge, and an exceptionally low self-discharge rate during storage.
-
Standard Quick-Connect Terminals: Fitted with reliable, highly conductive Faston spade tabs (F1/F2 standard layouts), ensuring a secure connection to standard power wiring harnesses with minimal voltage drop.
