What Makes a Battery Heavy-Duty?
Advanced battery technology designed for powerful loads and high electrical demands
Thicker Plates
Heavy-duty batteries feature lead plates 20-40% thicker than standard batteries, containing more active material for extended lifespan. Thicker construction withstands the constant cycling demands of commercial vehicles, lasting 4-6 years compared to 18-24 months for standard batteries in delivery vans, trucks, and high-use fleet applications.
Reinforced Grids
Reinforced grid construction resists vibration damage that destroys standard batteries. Commercial vehicles experience constant vibration from rough roads, diesel engines, and daily operation—the leading cause of battery failure. Heavy-duty grids use thicker framework and enhanced alloys to prevent grid corrosion and plate separation, extending lifespan by 3-4 years.
Higher CCA Ratings
Higher Cold Cranking Amps (700-900 CCA typical) provide reliable starting power for commercial diesel engines and larger vehicles. Diesel engines require 50-100% more cranking power than equivalent petrol engines, especially in cold weather. Heavy-duty batteries deliver the extra power needed for dependable starts, even with worn engines or cold conditions.
Larger Reserve Capacity
Extended reserve capacity (120-160 minutes typical) powers accessories longer with the engine off. Delivery vehicles, work vans, and service trucks run lights, refrigeration, tools, and equipment while parked—draining batteries rapidly. Larger capacity prevents deep discharge that damages standard batteries, ensuring reliable starting after extended accessory use.
