Product Specifications
Key Features
-
Premium AGM Technology: Incorporates advanced Absorbent Glass Mat (AGM) separators featuring an efficient gas recombination design of up to 99%. The system remains completely maintenance-free with zero need for distilled water replenishment.
-
Non-Spillable VRLA Construction: Built using a leak-proof Valve Regulated Lead Acid (VRLA) design and housed in a durable ABS shell. This ensures secure, spill-proof operation and allows flexible installation at almost any physical mounting angle.
-
Heavy-Duty Lead-Calcium Grids: Manufactured with high-purity lead-calcium-tin alloy grids, providing exceptional structural integrity, lower internal resistance, and a highly stable self-discharge rate during storage.
-
Standard Spade Terminals: Fitted with reliable, highly conductive Faston type terminals (standard configuration for quick-connect terminal clips) to maintain a secure electrical link and minimize connection power drops.
