12V 45Ah maintenance-free battery is designed specifically for automobiles, built for durability, and intended for export.

The maintenance-free car battery utilizes a modern, advanced, fully sealed lead-calcium alloy structure. Unlike traditional water-filled batteries, it experiences extremely low water loss during operation and requires no addition of distilled water or electrolyte throughout its entire lifespan.

The battery is pre-filled with electrolyte and completely sealed at the factory. Its casing features a scientifically designed labyrinthine venting system that re-condenses and recirculates distilled water, eliminating tedious daily maintenance and preventing acid spillage from corroding the vehicle.
